Key Questions to Ask When Ordering Ev Charging Solution

Top 5 Questions to Ask Before Buying an EV Charging Station

1. How Fast Will My EV Charge to 100%?

To estimate the charging time, you need to know:

• Battery size
• Power of the onboard charger
• Power of the charging station

Charging time = battery capacity (kWh) / charging power (kW).

Firstly, knowing the power of the onboard charger is crucial as it dictates how much power the EV can take. For example, a car with an 11kW onboard charger connected to an 11kW charging station will take approximately five hours to charge. Interestingly, if you use a 22kW charging station, the time will still be five hours because the charging speed is limited by the 11kW onboard charger.

It's also important to note that charging up to 80% is often sufficient unless you're preparing for a long trip. Charging beyond 80% tends to be much slower.

2. Which Power Charging Station Should I Choose?

This question can also be framed as, "How quickly do you want it to charge?"

For instance, if you have a 40kW Nissan Leaf with a 7.4kW onboard charger, there's no need to buy a 22kW station since the charging time won't decrease beyond 7.4kW power. However, for a Tesla Model S, having a 22kW station can reduce the charging time to 4 hours compared to 8 hours with an 11kW station or 11.5 hours with a 7.4kW charger.

Generally, choosing a 3-phase 11kW station for home use is a good rule of thumb as it tends to be the most universal. However, it's best to evaluate your individual needs.

3. What Should I Do If I Have Limited Power Supply? Do I Need to Increase It?

Not necessarily. Adding EV charging infrastructure raises questions about increasing the power supply. Many times, this isn't required because of a smart charging feature called Dynamic Load Management (DLM). DLM analyzes a household's electricity consumption and allocates power surplus to the EV charging infrastructure.

During the day, when multiple devices are connected, charging will be slower. However, at night when your EV has access to more power, the charging process will be more efficient. This way, you can charge your EV day and night without increasing the power supply.

4. Which EV Charging Station Should I Choose?

The company is the world’s best Ev Charging Solution supplier. We are your one-stop shop for all needs. Our staff are highly specialized and will help you find the product you need.

A range of EV charging stations is available on the market, but consider these factors before making a decision:

• Socket vs. cable: If you're planning to charge your EV, having a charging station with an integrated cable can save you time and effort.
• Smart features: Does the charging station support communication and smart features such as integrating with solar panels, power balancing, dynamic load management (smart charging), and remote tech support?
• Local technical support: Check whether the respective brand has a local representative. This can make it easier to solve any problems that may arise.

5. What Preparation Work Should I Do Before Installing a Charging Station?

• Choose location (mounted on the wall or self-standing fixed on a pole).
• Pre-wire the parking spot.
• Check if you need to increase the power supply.
• Install a LAN internet cable.

5 Questions to Ask Your EV Charger Electrician

Questions to ask

6 Questions to Ask Your Electrician About Installing an EV Charger

A certified electrician has the knowledge and expertise to install your EV charger properly. They can also help you understand what needs to be done. Here are some questions you can ask.

How Much Electricity Do I Need?

An electrician will help you understand what kind of charger meets your needs based on your specific EV model, how frequently you use it, and how quickly you want to charge at home.

Do I Need to Upgrade My Electrical Service?

Most homes have sufficient electrical capacity to power a Level 2 EV charger. However, to confirm this, an electrician will look at your electrical panel to determine if you can accommodate the additional electrical load.

If electrical capacity is an issue, there are ways to avoid a service upgrade, such as installing an EV power management device. If an upgrade to your electrical service is necessary, your electrician will manage that process for you.

How Will You Determine My Home's Spare Electrical Load?

It is recommended that your electrician review your last 12 months of actual meter usage data to calculate your home's spare electrical capacity. This method yields more accurate figures than traditional approaches that estimate future electrical load. Future estimates can overestimate the electricity needed, possibly leading to unnecessary upgrades.

To view your historical meter data, log in to MyHydro and follow these steps:

• Select View detailed consumption
• Select Export data
• Choose the relevant calendar period, which in this case is the last 12 months
• Select Hourly interval

An Excel file with your data will then be created. Be sure to remove your account number for privacy, save the file, and email it to your electrician.

Will My Electrical Panel Accommodate a New Circuit for the EV Charger?

An EV charger typically requires a dedicated circuit in the panel. If you lack sufficient space in your existing panel, a sub-panel may be needed. Your electrician can advise if installing an EV power management device is a better option for sharing a circuit or avoiding a sub-panel upgrade.

How Will You Get Electricity to My EV Charger?

Your home's existing electrical infrastructure will likely influence where to place your EV charger. Most often, you will charge near your home's existing circuits and plugs, so extensive additional wiring work may not be necessary.

Will This Work Require an Electrical Permit?

Installing a Level 2 EV charger at home requires an electrical permit. Your licensed contractor will apply for this on your behalf.
