5 Things to Know Before Buying 11kw Smart Home Ev Charger

You may still sometimes hear that charging station is not really needed to charge your EV at home since you can use the simple plug. Well, even though it is technically possible, it is really not recommended and not efficient. Firstly, it is not safe, secondly EV charging station speeds up the charging up to 9 times and also offers various smart features. But before you buy a charging station these are the important questions to answer. 

Goto Ruihua to know more.

1. How fast will my EV charge to 100%?

To estimate the charging time you need to know:

• Size of the battery
• Power of the onboard charger
• Power of the charging station

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

First of all it is important to know the power of the onboard charger of the EV because it determines how much power EV will be able to take. So, for example a car with 11kW onboard charger connected to 11kW charging station will take around 5 hours to charge. Interesting that if we have 22kW charging station charging time will remain 5 hours in this case as charging speed is limited to 11kW (power of the onboard charger).

Important to mention that charging to 80% is often enough (unless you are prepared for a longer trip) as after EV is charged up to 80% charging will be much slower for the remaining 20%.

2. Which power charging station should I choose?

We could twist the question and ask how fast do you want it to charge? 

For example if you own 40kW Nissan Leaf with 7,4kW onboard charger, there is no need to buy 22kW station as charging time will not decrease starting from charging at 7,4 kW power. However, owning Tesla Model S and having 22kW station can decrease the time needed to charge to 4 hours (compared to 8 hours charging with 11kW or 11,5 hours with 7,4kW charging station).

Rule of thumb would be choosing 3-phase 11kW station for home as it is the most universal, however should look individually what makes the most sense. 

3. What should I do if I have limited power supply? Do I need to increase it?

Not necessarily. While different devices in the building consume energy, adding EV charging infrastructure poses the question of whether we need to increase the power supply? In many cases it is not necessary because smart charging feature called Dynamic Load Management (DLM) is meant to analyze a household’s electricity consumption and allocate the power surplus to the EV charging infrastructure.

During the day, when multiple devices are connected – charging will be slower, but as days are made for driving and nights for charging, at night your EV will have access to more power. This way you will be able to charge your EV day and night without increasing the power supply.

4. Which EV charging station should I choose?

There is a wide range of range of EV charging stations on the market, however these are important things to think about before making a decision:

• Socket vs cable. If you are planning to charge your EV then it is very very convenient to buy a charging station already with integrated cable, will save you time and effort.
• Smart features of the charging station. Does charging station come with communication and supports the smart features such as integrating with solar panels, power balancing, dynamic load management (smart charging), remote tech support and others.
• Local technical support. Check whether there is a local representative of the respective brand, it will make it easier and faster to solve the problem if it even occurs. 

5. What preparation work should I do before installing a charging station?

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

Electric vehicle chargers, commonly known as EV chargers, are the essential infrastructure that enables electric vehicles (EVs) to recharge their batteries. These chargers are the lifelines of the growing electric vehicle ecosystem. They come in various forms and sizes, but their primary purpose remains consistent: to provide electrical energy to your EV, ensuring it stays powered and ready for your journeys. Whether you're at home, work, or a public charging station, understanding the different aspects of EV chargers is crucial for all EV owners.

Smart EV chargers represent the pinnacle of modern charging technology, offering a range of advanced features and benefits. These chargers are not just about replenishing your EV's battery; they are intelligent systems designed to optimize your charging experience.

At the heart of smart EV chargers is connectivity. They are equipped with technology that allows them to communicate with your EV, your home energy system, and, in some cases, even the grid. This connectivity opens up a world of possibilities:

Dynamic Charging Speed: Smart chargers can adjust the charging rate based on factors such as electricity prices, grid demand, and your preferred schedule. This means they can charge your EV faster when electricity costs are low, saving you money.

Remote Monitoring and Control: Many smart chargers come with mobile apps or online platforms that let you monitor and control the charging process from anywhere. You can check the status of your EV's charge, set charging schedules, and receive notifications.

Load Balancing: Smart chargers can distribute the available electrical capacity among multiple devices, ensuring that your home's electrical system remains stable while charging your EV.

Renewable Energy Integration: Some smart chargers can sync with renewable energy sources, such as solar panels or wind turbines, to charge your EV when clean energy is abundant.

Types of EV Charger

EV chargers come in different types, each catering to various needs and situations. Here are the three primary types:

Level 1 Chargers (120V): These chargers use a standard household electrical outlet and are typically included with your EV. While they are the slowest option, they are convenient for overnight charging at home.

Level 2 Chargers (240V): Level 2 chargers are the most common choice for home charging. They offer faster charging speeds than Level 1 chargers, making them suitable for daily use.

DC Fast Chargers: DC fast chargers are the quickest option and are typically found at public charging stations. They are perfect for long-distance travel and quick top-ups but are less common for home use due to their high cost and power requirements.

The choice of EV charger depends on your daily driving habits, access to charging infrastructure, and the convenience you seek in your EV ownership experience.

Tips on Buying an Electric Vehicle Charger

When purchasing an electric vehicle charger, consider the following tips:

Compatibility: Ensure that the charger you choose is compatible with your EV's charging port. Different EV models may have varying plug types, so check your vehicle's specifications.

Charging Speed: Assess your daily charging needs. If you have a long commute or plan for extended trips, a faster charger (Level 2 or DC fast charger) may be more appropriate.

Installation: Factor in the installation requirements and costs. Level 2 chargers often require professional installation and may necessitate electrical upgrades to your home.

Smart Features: Decide whether you want advanced features like remote monitoring and energy optimization. Select a smart EV charger that aligns with your preferences and needs.

Warranty and Support: Verify that the charger comes with a warranty and offers reliable customer support. As EV chargers are long-term investments, having access to assistance is crucial for peace of mind.

Smart chargers offer advanced features that can enhance your charging experience, while different charger types cater to various needs. By following these tips, you can confidently choose the right EV charger that suits your lifestyle and ensures your EV stays charged and ready for the road ahead.
