If you have the option of installing a Level 2 home charger, it can easily be one of the best investments you can make as an EV owner. Whether you have a battery-electric vehicle (BEV) or a plug-in hybrid electric vehicle (PHEV), 80-90% of your charging will likely be done at home.

With so many brands, price ranges, specs, and features for home chargers, how do you choose the one that&#;s right for you? Here are some tips on what to look for in an EV home charger.

Why You Should Consider Level 2 Charging

Let&#;s first go over the two different levels of charging that are available at your home.

Level 1 charging uses a standard 110-volt AC outlet that you commonly use around your home. This is the slowest level of charging available and can add 1-2 kW of energy to your vehicle per hour. In a battery-electric vehicle (BEV) like the Hyundai IONIQ 5 with a 77.4-kWh battery, it can take a few days to charge from completely empty to completely full. In some cases, your vehicle may come equipped with a Level 1 charging cable that you just need to plug in to your standard household outlet.

Level 2 charging uses a 240-volt AC outlet or circuit, similar to what is used for an electric stove or dryer. All home EV chargers use Level 2 charging. The higher voltage allows for more power to be delivered to your EV in a shorter period of time than a Level 1 charger. A Level 2 charger can add around 7-10 kW of energy to your vehicle per hour. The same Hyundai IONIQ 5 can take around seven hours to charge from completely empty to completely full.

If you drive a plug-in hybrid vehicle, a Level 1 charger may be sufficient for your needs, depending on the size of the battery or mileage, bur if you have a battery-electric vehicle, a Level 2 charger is a much better choice.

How Much Does a Home Charger Cost?

Before you start shopping for a home charger, it&#;s best to first understand how you use your EV and your budget.

Take note of your average daily mileage as well as the battery level (state of charge) when you arrive back home. If you&#;re like many Americans, your daily round-trip commute may only be around 40 miles. With a relatively short commute, you&#;ll likely return home with a relatively high state of charge. In fact, you may be able to go days without draining the battery completely and needing to charge. However, if you have a longer commute, like 100 or more miles daily. or drive more on the highway, you might arrive back home with a lower state of charge and need to charge your EV more frequently.

Understanding how often you need to charge will help determine the type of home charger needed for your daily commute. Remember that you only need to charge to replace what you&#;ve used during the day. Depending on your driving, you might not deplete the battery completely each day.

Home charger units vary in cost. They can be as little as $200 to a over $1,000, depending on the brand, capability, and features. Don&#;t forget that you&#;ll need to budget for installation costs, which can vary greatly depending on your home&#;s electrical system and where you want the charger located.

For example, installation costs can be minimal if you already have a dedicated 240-volt circuit in your garage. In contrast, installation costs can be significantly higher if you need to upgrade your home&#;s entire electrical system. Hire a licensed electrical contractor to perform a load calculation to see if your home can support a dedicated circuit for your home charger. They can also determine what&#;s needed to install the charger at your desired location.

Wi-Fi Smart Chargers

Many chargers are Smart or Wi-Fi-enabled. They allows you to control certain charger functions through a mobile app that&#;s installed on your smartphone or tablet.

Depending on the charger, you can start or stop the charge remotely, schedule a time to start and stop the charging, monitor the battery&#;s state of charge and energy flow, and monitor the time remaining to a full battery charge. Some smart chargers allow for firmware updates and repair diagnostics for servicing. Virtual assistant enabled chargers allow you to control certain functions using Alexa or the Google Assistant.

If you own a newer EV model, you might not need a smart charger. Many modern EVs allow you to control charging functions and monitor the charging status either through the vehicle itself or through the vehicle&#;s mobile app.

For example, the Hyundai IONIQ 5 can come equipped with Hyundai&#;s Bluelink connected vehicle system, which allows you to control and monitor your charging functions from the Hyundai app. That said, some smart chargers offer connectivity features that a vehicle may not. It's always best to compare the vehicle&#;s connectivity features with a smart charger to determine the smart features that you want.

Understanding Charger Amperage

Home chargers come in different amperage (A) ratings, which helps determine how much power can be delivered to your EV. You&#;ll likely come across chargers in 30A, 40A, 48A, 60A, or even 80A. Some chargers have an adjustable current feature that allows you to adjust the amperage. What&#;s the right amperage for you?

The maximum amperage will be dictated by:

1. The maximum amount of AC energy that your EV can accept
2. Your home&#;s electrical system

Not all EVs can accept the same amount of electrical power, which determines the rate at which they charge. The amount of AC electrical energy that each EV can accept is limited by its onboard AC charging system.

For example, a Toyota BZ4X battery-electric can accept up to 6.6kW (28A). Whereas a Hyundai IONIQ 5 battery-electric can accept up to 11kW (48A). If you charge each vehicle with a 30A charger, the BZ4X will be charge at its maximum rate. The IONIQ 5 can still charge with the 30A charger, but it&#;s capable of charging at a higher rate since it can accept up to 48A.

If you charge each vehicle with a 48A charger, the BZ4X will not charge any faster since it&#;s capped at 28A, while the IONIQ 5 will charge faster since it can charge up to 48A. Find a charger with an amperage that best fits your EV&#;s capability.

With that in mind, most people won&#;t need to charge at the highest amperage, especially if you are charging overnight or don&#;t need to replenish a lot of the battery in a short amount of time. For example, if you only drive 40 miles a day in the city, you&#;re likely not to use up a lot of the battery. Charging with a 30A charger is more than sufficient to replenish the battery, especially if it&#;s overnight.

How much power your home&#;s electrical system can deliver is also a limiting factor. Most homes in North America have ratings of either 100A or 200A. The maximum amperage for your EV charger will depend the amount of unused amperage left in your breaker panel.

For example, if you have a 200A breaker panel and only half of it is used for your devices and appliances, you&#;ll likely have plenty of capacity to install a 48A charger. On the other hand, if your breaker panel is completely full, you may need to upgrade your home&#;s electrical system to accept additional devices like an EV charger. To determine the maximum charger amperage that your home can handle, it&#;s always best to consult a licensed electrical contractor.

Home Chargers: Plug-in or Hardwired?

Some chargers can connect directly to your home&#;s electrical system, while others can be plugged into a 240V outlet.

Plug-in chargers can be plugged into a 240-volt outlet that&#;s similar to a dryer outlet, most commonly referred to as a NEMA 14-50 or 6-50 outlet. Portability is the main advantage of plug-in chargers. For example, if you&#;re driving to the cottage or a camp site that has a compatible outlet, you can bring the charger with you and just plug it in to charge your EV. If you&#;re renting or planning to move, you can take the charger with you to your new home.

Hardwired chargers are directly wired to your home&#;s electrical system. Unlike plug-in chargers, these chargers don&#;t provide the convenience of portability. However, hardwired chargers reduce the number of electrical connections, thereby reducing the number potential failure points within the circuit. Additionally, NEMA 14-50 or 6-50 plugs can only support up to 40A for EV chargers. So, if you need a higher amperage charger, such as a 48A or 80A, hardwired is the only method.

Indoor or Outdoor Rated EV Chargers

If you&#;re looking to install a charger outside of your house or garage, you&#;ll need to ensure that it&#;s rated for outdoor use. This is particularly critical if you live in an area where you want to protect the charger in harsh weather conditions, such as rain, snow, or even high winds.

EV chargers usually have a NEMA enclosure rating of NEMA 3, 3R, 4, or 4X. These ratings measure the charger enclosure&#;s ability to withstand various environmental conditions in order to safely protect the electrical components and users. Chargers with a 4X rating are ideal for outdoor use and harsh climates as they offer the highest amount of protection.

For extreme cold winters, you also want to look for a cable that remains pliable when the temperature drops. This is especially the case since many chargers come with a 20-foot or longer cable. For extreme winter or summer temperatures, you also want to find a charger that has a wide operating temperature, such as from -22F to 122F (-30C - +50C).

EV Charging Connector Types

For AC charging there are only two connector types &#; the Tesla connector (also known as the NACS or J) and the J connector.

If you currently own a non-Tesla EV, like a Hyundai IONIQ 5 or Toyota BZ4X, the vehicle will have a J connector. If you own a Tesla model, you will need a J connector. However, with the North American auto and EV industries adapting the Tesla connector as a new standard over the next few years, most future EVs and charging equipment will come with the Tesla-style J connector.

There are adapters that you can buy that will allow you to charge from a J to a Tesla/J connector. Likewise, there are adapters that will also allow you to charge from a Tesla/J to a J connector. However, where possible, it&#;s always best to charge without an adapter to reduce the number of potential failure points.

Warranty and Certification for EV Chargers

For a trouble-free home charging experience, always ensure that the home charger is well warrantied and properly certified.

Find a charger that is covered by a warranty for at least three years for parts and labor. You may find chargers at a very low cost, but offer a very limited warranty and customer service. It&#;s always a better idea to invest in a well-built charger that is backed by a longer comprehensive warranty as well as outstanding customer service.

Many household appliances are Energy Star certified, which are products that meet strict energy-efficiency specifications determined by the U.S. Environmental Protection Agency (EPA). An Energy Star certified EV charger will help ensure that the charger uses your home&#;s electricity efficiently when charging your EV.

An EV home charger operates continuously at a high voltage and amperage. Look for a charger that meets or exceeds safety standards in your area. If you&#;re in Canada, look for chargers that are certified by the Canadian Standards Association (CSA). In both the U.S. and Canada, look for chargers with a UL or cUL (Underwriters Laboratories) certification.

Future-Proofing Your EV Charging

Whether this is your first EV or you&#;re replacing another EV, it&#;s likely not going to be your last one. As EV adoption increases, EV battery and charging technology will continue to improve.

Future EVs may charge at higher rates and require higher amperage. A 30A home charger may be more than sufficient for today&#;s vehicle, but a 48A, 60A, or 80A charger may be better for future vehicles. To help future proof your decision, find a charger with the highest amperage that you can afford and your home can support.

Even if you install a lower amperage charger today, oversizing the wires during the installation can support higher amperage chargers in the future. You can also find a charger that allows you to adjust the amperage up or down to meet your needs today and into the near future.

If you&#;re looking to purchase a second EV in the near future, it may also be a good idea to buy a charger designed to charge two vehicles at the same time. These chargers have two cables and connectors to charge two vehicles. They can operate on one circuit but intelligently split the power between the two vehicles. Another option is to run the wires for a second charger on a second dedicated circuit during the installation of your first EV charger. The electrician can install a NEMA 14-50 or 6-50 outlet so that can be used for future use.

Hire a Licensed Electrical Contractor

Regardless of the home charger that you&#;re looking to purchase, always ensure that you have a permit if required in your area, and the installation performed by a licensed electrical contractor. Look for an electrical contractor who is familiar with EVs and charging equipment. EV charging equipment are unlike other appliances in your home since they draw continuous power over a longer period of time. Always consult the legal requirements in your area before installing an EV charger in your home.

With so many chargers on the market today, it can be a bit overwhelming to find the right one that best fits your needs. In general, it&#;s a good idea to buy the best charger in terms of features, amperage, durability, and certification that you can afford. This will not only ensure a great charging experience, but also will help protect two of your biggest investments &#; your home and your EV.

2. Electric vehicles vs. gas

EV charging is one of the reasons you should get an electric car

Whether you&#;re in the market for your first EV or considering upgrading, it&#;s only logical that you&#;re comparing your options. One of the major differences between owning an EV and a traditional vehicle with an internal combustion engine (ICE) is how you fill your proverbial tank. Many find switching from putting gas in a tank to charging a battery with electricity the scariest transition; what if you run out in the middle of nowhere?

In reality, EV range anxiety has as much to do with psychology as it does with the range of electric cars (or the availability of charging stations). In fact, being able to charge your battery is one of the best things about driving an electric car.

The biggest difference between driving gas and electric is that when you&#;re driving electric, you can charge potentially anywhere.

EV charging locations

It may sound obvious, but with a gas vehicle, you can pretty much only fill up your tank at a gas station. With an EV, however, you can charge your car pretty much everywhere: at home, at the office, at a restaurant, whilst doing your shopping, whilst parked on the street, or you can top-up your car&#;s battery at a (no longer aptly named) gas station.

So, the decision to get an EV and thinking about how to charge it go hand in hand. However, because it works a little differently than what we&#;re all familiar with, it can get quite confusing, especially because there are many new definitions you have to wrap your head around.

Electric car charging explained: why is the terminology so complicated?

As a relatively young, scattered, and rapidly growing industry, EV charging terminology is all over the place. There are different charging levels, cables and plugs (which differ depending on where you are), battery capacity possibilities, and estimated actual range.

Charging stations can also vary depending on the type of current they use (AC or DC), their power output, and their charging speed. It doesn&#;t help that many EV charging terms are similar and often used interchangeably. For example, how fast is fast charging really? And what is rapid or even ultra-fast charging?

If you&#;re thinking about buying (or have just bought) an EV, then it&#;s understandable that all this new information can feel a bit overwhelming.

Read on to learn everything you need to know about EV charging so you can start your transition toward electric mobility well-informed.

3. Where to charge an electric car?

EV charging locations

Generally speaking, any location you can park your car in with access to electricity is a potential charging location. So, you can imagine the places you can charge your EV are as diverse as today&#;s electric car models.

As the world is shifting towards electric mobility, the need for a suitable charging infrastructure network has never been more prevalent. As such, governments and cities across the globe are creating legislation and incentivizing the building of charging stations while more and more businesses are tapping into this new market.

The number of publicly available charging stations is steadily increasing and will continue to do so to keep pace with the rapidly growing adoption of electric vehicles across the world.

So in the future, as charging stations become more common fixtures on streets the world over, the locations you will be able to charge in will expand greatly. But what are the five most popular places to charge your car today?

The five most popular car charging locations

According to our Mobility Monitor report in partnership with Ipsos, in which we surveyed thousands of EV drivers (and potential EV drivers) across Europe, these are the five most popular places to charge an electric car:

1. Electric car charging at home

With 64 percent of EV drivers charging regularly at their house, home EV charging takes the crown for the most popular charging location. This comes as no surprise, as charging at home enables electric car drivers to wake up to a fully charged vehicle every day and ensures they pay only for the electricity they consume at their household's electricity rate.

2. Electric car charging at work

34 percent of current EV drivers already regularly charge their car at the workplace, and many more have stated that they would love to be able to do so, and who wouldn&#;t? Driving to the office, focusing on your work during business hours, and driving home at the end of the day in a fully charged vehicle is undoubtedly convenient. As a result, more and more workplaces are starting to install EV charging stations as part of a sustainability initiative, employee engagement strategies, and to satisfy their EV-driving visitors and partners.

3. Public charging stations

Each day, more public charging stations are popping up as cities and local governments are investing heavily in charging infrastructure. Today, 31 percent of EV drivers already use them regularly, and they are likely to play a crucial role in supporting electrification for city dwellers without access to a home charging station.

4. EV charging at gas stations

Charging at home or at the office sounds nice, but what if you&#;re on the road and looking for a quick top-up? Many fuel retailers and service stations are starting to provide fast charging (also known as level 3 or DC charging). 29 percent of current EV drivers already charge their car there regularly.

While charging at the office or at home is convenient while you get on with your day, it can take hours to fully charge a battery, depending on the charging station&#;s power output. For times when you need a quick top-up, fast charging stations allow you to charge your battery in minutes, not hours, and be back on the road in no time.

5. Retail locations with electric car chargers

26 percent of EV drivers regularly charge their car at supermarkets, while 22 percent prefer shopping malls or department stores&#;if the service is available to them. Think of the convenience: imagine watching a movie, having dinner, meeting a friend for a coffee, or even doing some grocery shopping and returning to a vehicle with more charge than you left it with. More and more retail locations are discovering the growing need for this service and are installing charging stations to meet the demand and acquire new customers.

4. Different types of chargers

EV charging levels and all types of chargers explained

Charging can be categorized in multiple ways. The most common way to think about EV charging is in terms of charging levels. There are three levels of EV charging: Level 1, Level 2, and Level 3&#;and generally speaking, the higher the level, the higher the power output and the faster your new vehicle will charge.

Generally speaking, the higher the level, the higher the power output and the faster your new vehicle will charge.

However, in practice, charging times are influenced by many things like the car's battery, charging capacity, the charging station's power output. But also the battery temperature, how full your battery is when you start charging, and whether you&#;re sharing a charging station with another car or not can also influence the charging speed.

The maximum charging capacity at a given level is determined either by your car&#;s charging capacity or the charging station&#;s power output, whichever is lower.

Level 1 charger

Level 1 charging simply refers to plugging your EV into a standard power socket. Depending on where you are in the world, a typical wall outlet only delivers a maximum of 2.3 kW, so charging via a Level 1 charger is the slowest way to charge an EV&#;giving only 6 to 8 kilometers of range per hour (4 to 5 miles). As there is no communication between the power outlet and the vehicle, this method is not only slow, but it can also be dangerous if handled improperly. As such, we don&#;t recommend relying on Level 1 charging to charge your vehicle except as a last resort.

Level 2 charger

A Level 2 charger is a dedicated charging station that you may find mounted to a wall, on a pole, or standing on the ground. Level 2 charging stations deliver alternating current (AC) and have a power output between 3.4 kW - 22 kW. They are commonly found at residential, public parking, businesses, and commercial locations and make up the majority of public EV chargers.

At the maximum output of 22 kW, an hour&#;s charging will provide roughly 120 km (75 miles) to your battery&#;s range. Even lower power outputs of 7.4 kW and 11 kW will charge your EV much faster than Level 1 charging, adding 40 km (25 miles) and 60 km (37 miles) of range per hour respectively.

Because of this reason, and thanks to a range of smart charging options, connectivity and safety features that Level 2 AC chargers offer, many EV drivers invest in an AC charging station for their home.

Level 3 charging station (DC fast charger)

Also known as DC or fast charging, Level 3 charging uses direct current (DC) to charge a vehicle&#;s battery directly, instead of the alternating current (AC) used by Level 1 and 2 charging stations. This allows Level 3 chargers to bypass an EV&#;s slower AC/DC onboard converter and deliver DC power directly to the battery.

As a result, Level 3 charging stations can deliver much more power faster, making them ideal for short-stop locations like gas stations and fleet depots. Charging times vary between different vehicles and power outputs, however, generally speaking, Level 3 chargers can charge a vehicle in minutes versus hours for Level 2 or days for Level 1 charging stations.

AC vs DC power

So, the higher the level, the higher the charging speed. All clear so far, right? But what is AC and DC? When is something AC and when DC, and why is DC so much faster?

AC vs DC current

AC stands for &#;Alternating Current&#;, and as its name implies, it changes direction periodically. DC stands for &#;Direct Current&#; and flows in a straight line. Without getting too technical, AC can be transported over long distances more efficiently, so this is why it flows out of your socket at your home and office. However, batteries are only able to store DC power, and electronics use DC to operate.

You may have never realized it, but every time you charge your (or any other electrical device for that matter), the charger converts the AC power it receives from the grid into DC power to charge the battery in your device.

How do electric cars charge?

The same principle goes for electric cars. The difference between AC and DC charging all depends on whether there is a conversion process or not. No matter how you charge it though, at the end of the day, the electricity stored in the car&#;s battery is always DC.

With a DC charger, power is converted from AC to DC by the charger, allowing direct current to flow straight into the battery. With an AC charger, the electricity has to be converted to DC by the car&#;s built-in converter before it can be fed into the battery. This process will always take longer as the onboard charger has a much more limited capacity than the external converters used in DC charging stations.

5. How long does it take to charge an electric car?

What is the average time to charge an electric car and what affects charging speed?

Once you&#;ve got your head around where to charge, what the different levels of charging are, and have a basic understanding of the difference between AC and DC, you can now better understand the answer to the number one question: &#;So how long will it take to charge my new EV?&#;.

How long it takes precisely to charge an EV depends on different factors, such as your vehicle&#;s battery size, charging capacity, as well as a number of other situational factors. But, to give you an idea, here's a quick overview of average charging time estimates for a medium-sized EV.

Level 1 (AC)

About 19 hours

Level 2 (AC)

Between 1h 45 min - 6h

Level 3 (DC)

Between 17 min - 52 min

To give you a somewhat accurate approximation, we&#;ve added an overview of how long it takes to charge EVs below. This overview looks at three average battery sizes and a few different charging power outputs. For a more detailed overview of a specific model, have a look at our electric car specifications page.

Electric car charging times

*Approximate time to charge the battery from 20 percent to 80 percent state of charge (SoC).
For illustrative purposes only: Does not reflect exact charging times, some vehicles will not be able to handle certain power inputs and/or do not support fast charging.

What affects charging speeds?

Electric car battery

The bigger the battery, the longer it will take to charge. Simple, right? An EV's battery capacity is measured in kilowatt-hours (kWh), similar to a liter or a gallon but for electricity, with each kWh equal to the amount of energy you would use to run a 1,000-watt appliance for an hour. The vast majority of electric passenger vehicle batteries today can hold somewhere between 25 and 100 kWh when fully charged, with the average EV having a 69 kWh battery capacity.

Charging capacity of the vehicle

The maximum power an EV can accept differs from vehicle to vehicle and can even vary depending on the model of the car. Measured in kilowatts (kW), the charging capacity is shown for both AC charging and DC charging, and each is a large factor in determining how long it takes to charge. For instance, if two vehicles with similar-sized batteries are charging side by side at a high-power DC charging station, but one can only accept 50 kW of DC power and the other 250 kW, then the latter will charge much faster than the former.

Charging output of the charging station

The different output of the charging station plays a large factor in how long it takes to charge an EV. The higher the kW output on a charging station, the faster it can charge (presuming that your vehicle can handle the higher power output).

State of charge

It might sound obvious, but how much charge you have in your vehicle when you begin your charging session also plays a part in how long it takes to charge. The same as when you&#;re putting gas in a traditional vehicle, depending on whether you have half a tank or are almost empty, how long it takes to charge will differ.

The DC charging curve

With AC charging, the power flow from the charger to an EV is mostly flat, meaning that it will charge at roughly the same speed from 0-100 percent full. In contrast, with DC charging, the EV&#;s battery initially accepts a very high flow of power, then quickly peaks and starts to decrease the power it takes in as it begins to fill up.

The reason for this pattern is twofold. You might remember from above that with AC charging, the conversion from AC to DC happens inside the vehicle by the onboard converter. This has a fairly limited power capacity, which is quickly reached and can be sustained throughout the whole charging session.

DC charging, on the other hand, unlocks much greater power output, so it needs to adjust this as the session progresses to avoid damaging the battery. Because of their chemistry, EV batteries can take in much higher power at low states of charge, and this ability decreases progressively as they get closer to full.

As a result, with a DC or Level 3 charger, the initial phase of charging (to 80 percent full) is much faster than the last 20 percent (which may take roughly the same amount of time as the first 80 percent).

Weather conditions

Another factor that will determine charging times is the weather. As batteries operate more efficiently in temperate weather&#;roughly between 20&#;25°C (68-77°F)&#;it will take longer to charge a vehicle in colder or extremely warm weather.

6. How much does it cost to charge an electric car?

Cost to charge electric car

Just like with how long it takes to charge an EV, the cost of charging depends on multiple variables including where you charge it, or the type of vehicle you drive.

Before we get into it in greater detail, here are the approximate costs of charging four different size vehicles (with battery packs from small to large), at three different types of charging stations, so that you can get a ballpark idea of charging costs for your new EV.

Average cost to charge electric car

Important: Prices for each charging segment are approximations based on our experience and do not represent a real-life situation. These calculations are based on a median guesstimate charging tariff and represent the cost to charge from zero to 100 percent.

Size of the electric car battery

The first thing you need to know when calculating how much it costs to charge your EV is the size of your battery. As shown above, the larger the battery, the more kWhs it can store; the more kWhs it can store, the more power it takes to fill the battery; the more power it takes, the more you have to pay to fill your battery. Simple, right?

Vehicles with a larger battery cost more to charge, but can often drive further on a single charge too.

For instance, a Tesla Model 3 Long Range with an 82 kWh battery costs about $12.30 to fully charge at home but has a range of roughly 614 km (381 miles). However, a Fiat 500e with a much smaller 42 kWh battery, while costing a fraction of the price to charge, only has a 321 km (200 miles) range.

Once you know how big your new EV&#;s battery is (measured in kWh), you can approximate how much it costs to charge at different charging stations. The three main options are at home, at public locations, or at fast-charging stations.

EV home charging cost

Charging from home is the cheapest way to charge your new car. Because there&#;s no middle man standing in between you and the cost of energy, you&#;ll always get the cheapest rate available to consumers at home.

Electric car electric bill

How much it costs to charge at home is an easy equation. Simply take your latest energy bill and find the price per kWh you pay at home and multiply it by the size of your battery.

On average, residential prices for electricity vary from around &#;/$0.10 on the low end in Europe and North America to &#;/$0.32 on the higher end.

At the time of writing this guide, we&#;ve taken some averages around the world from Energybot (US), the European Union (EU), and Nimblefins (UK):

• United States: $ 0.15 per kWh
• European Union: &#; 0.28 per kWh
• United Kingdom: £ 0.33 per kWh

That means if you&#;ve just bought a Tesla Model 3 with an 82 kWh battery and pay $0.15 for electricity, you&#;ll be set back around $12.30 to fully charge your EV.

While this calculation gives an estimation of home charging costs, it doesn&#;t take into account the battery&#;s current state of charge, the state of your battery in general, weather conditions, or the type of charger, which can all impact your actual costs.

Cost of charging electric car at public station

Public charging stations can range from offices to curbside stations and commercial parking garages to shopping malls, restaurants, and hotels. The truth is that today, there&#;s no shortage of businesses big and small investing in EV charging. At the same time, cities and governments are investing in EV charging infrastructure to accelerate the shift towards sustainable mobility. When you put both together, you&#;ve got charging stations springing up in a range of locations.

Public charging stations can be either Level 2 or Level 3 (AC or DC charging stations) stations but, for simplicity, we&#;ve split them into two categories and will discuss them separately as they usually come with very different costs.

In both cases, public charging has a middleman providing the service (called charge point operators), so public charging stations usually have a marked-up price in comparison to home charging. How much it costs to charge depends on the base price of electricity in your location and how much the provider charges you for the service.

In some cases, like workplaces and offices, the provider is also an employer and will provide EV charging as an employee benefit and may charge less, or even allow employees to charge for free. Others, like parking facilities and shopping malls, will take the price of electricity and mark it up to make a profit on it, like any other service they offer. Some, like restaurants and hotels, may use EV charging as a way to attract new customers and offer free or discounted charging to patrons.

Just like the diversity in how much it costs, how these providers will calculate costs also differs greatly. Below is a list of the four most common ways to calculate charging tariffs.

• Connection fee: a fixed amount for each session.
• Energy fee: a certain price per kWh used during the charging session.
  
• Time fee: Cost per minute or hour.
• Service fee: A one-off markup for providing the service.
  

For example, a charging provider might charge $0.35 per kWh with a $1 service fee, meaning it would cost you $29.70 to fully charge a Tesla Model 3 with an 82 kWh battery.

How much it costs in practice for you depends on the provider, your country and region. While public charging tends to be more expensive, it is often faster than charging at home, and still cheaper than gas.

Cost to charge electric car at a DC fast charger

Level 3 or DC charging is the fastest way to charge an EV. Depending on the power output and your vehicle&#;s fast charging capabilities, it will likely take somewhere between 15 minutes and an hour to charge your EV up to 80 percent full. These speeds make DC charging stations perfect for quick top-ups at on-the-go locations like highway rest stops, gas stations, or supermarkets.

However, DC charging stations are also the most expensive to build and run. To enable these charging times, DC charging stations have to deliver serious amounts of power to a vehicle&#;s battery&#;think between 50 and 350 kW rather than 22 kW, the maximum output for AC charging stations.

As a result of these high installation and operating costs, charging service providers will often ask for a much higher price to pass on some of their expenses to the customer. In some cases, DC fast charging stations can cost double, or even triple, the kWh price of electricity&#;making the costs here similar to the cost of filling up your tank with fossil fuels.

Typical costs can range from $0.60 per kWh with a $2 service fee to a flat rate of $0.99 per minute. This means that to fully charge the same Tesla Model 3 as above, it would be closer to $50 for a full battery. But where filling up your tank at the gas station is the only option for ICE vehicles, DC fast charging is more of a sporadic convenience on long trips than an everyday tool for your daily commute.

Cost of electric car vs. gas

One of the questions we hear potential EV drivers ask us all the time is, are EVs cheaper to charge than filling up a conventional fossil-fuel vehicle? As you may have guessed by now, the answer to that question is almost always yes.

Regardless of charging costs for individual sessions, when you take into account that most EV drivers charge at home, occasionally topping up when shopping or at the workplace, and using fast charging for long-distance journeys, EV charging is usually a lot cheaper than filling a car with gasoline or diesel.

7. How far can an electric car go?

Electric car range

Another question many potential EV drivers want to know before buying an EV is, &#;how far will I be able to drive with my new car?&#; Or should we say, the real question on everyone&#;s mind is, &#;Am I going to run out of charge on a long-distance journey?&#; This concern is understandable; charging a battery is one of the main differences with driving an ICE vehicle and a question on many people&#;s minds.

In the early days of electric mobility, range anxiety gripped many potential EV drivers. And not without reason: Ten years ago, the best-selling EV, the Nissan LEAF, had a maximum range of only 175 km (109 miles). Today, the average range of EVs is nearly more than double that at 348 km (216 miles), and many EVs have a range of above 500 km (300 miles); plenty for even the longer daily urban commutes.

This increase in range, together with the rapid development of charging infrastructure, means range anxiety is becoming increasingly unwarranted.

But what about long trips? Even EVs with the furthest range may still need to stop and charge on a long journey. This is where DC fast charging stations come in &#; with their high power, they can quickly top up your battery while you stop to eat, stretch your legs, or take a bathroom break. And while it depends on where you live, fast charging infrastructure is growing rapidly and is already widely accessible across the US, UK, EU, and China.

Should I charge my electric car every night?

Most EV drivers won&#;t even have to charge their car daily. Did you know that in the US, the average American drives roughly 62 km (39 miles) a day and in Europe, the daily kilometers driven by car are on average, less than half of what they drive in the US?

The bottom line is that most of our daily commutes won&#;t even come close to reaching an EV's maximum range, regardless of the make or model, and even back in . For a more detailed overview of the range of any specific model, you can have a look at our electric car specifications page.

9. EV charging cables and charger plugs

EV charging connector types explained

Many of the sections above have answered questions you may or may not have had before purchasing your new EV. However, we can take a guess that you probably haven&#;t even thought about charging cables and plugs, the world of EV cables and plugs is as diverse as it is complex.

As different regions adopted EVs simultaneously, each developed its own cables and plugs, and there&#;s still no universal standard for charging to this day. As a result, just like Apple has one charging port and Samsung has another, many different EV manufacturers and countries use different charging technologies. To get a detailed overview of a specific model, our electric car specifications page shows the type of plug types and other specifications per car.

Broadly speaking, the two main ways EV charging can differ are the cable connecting the car to the charging station or wall outlet and the type of plug used to connect the vehicle to the charging station.

EV cables

Charging cables come in four modes. While each is most commonly used with a specific type of charging, these modes do not necessarily always correlate to the &#;level&#; of charging.

Mode 1

Mode 1 charging cables are used to connect light electric vehicles like e-bikes and scooters to a standard wall outlet and cannot be used to charge EVs. Their lack of communication between the vehicle and the charging point, as well as their limited power capacity, make them unsafe for EV charging.

Mode 2

When you purchase an EV, it will typically come with what&#;s known as a Mode 2 charging cable. This type of cable allows you to connect your EV to a standard household outlet and use it to charge your vehicle with a maximum power output of around 2.3 kW. Mode 2 charging cables feature an In-Cable Control and Protection Device (IC-CPD) which manages the charging process and makes this cable much safer than Mode 1.

Mode 3

A Mode 3 charging cable connects your vehicle to a dedicated EV charging station and is considered to be the most common for AC charging. Mode 3 cables can either be built into a charging station or removable &#; in fact, many EV manufacturers will provide a Mode 3 cable with their new cars to enable public charging.

Mode 4

Mode 4 charging cables are used when fast charging. These cables are designed to transfer the higher power from DC (level 3) charging, must be connected to a charging station, and are often even liquid-cooled to deal with the heat.

EV charging plug types (AC)

The charging plug is a connector that you insert into the charging socket of an electric car. These plugs can differ based on power output, the make of the vehicle, and the country the car was manufactured in.

You&#;ll find that EV charging plugs can be mostly broken down by region and whether they&#;re used for AC or DC fast charging. For example, the EU primarily uses Type 2 connectors for AC charging, while the US uses CCS1 for DC fast charging.

What about the Tesla charging plug?

There is one exception to the charging plugs presented above, and that&#;s Tesla&#;s proprietary charging plug used by the company for its North American vehicles. Recently, Tesla opened up its charging plug for other manufacturers to adopt, now called the North American Charging Standard (NACS). This will mean that the existing Type 1 and NACS will likely coexist for a while in the American market, and time will tell which &#; and whether &#; one will come out on top.
