Power and current of 7KW AC charging station: how to match your electric vehicle.

The power and current of a 7KW AC charging station, as well as how to match it with an electric vehicle, can be answered from the following aspects:

1、 Basic parameters of 7KW AC charging station
1. Power: 7KW, suitable for daily household use, can balance charging speed and grid load.
2. Voltage/Current: Typically, 220V single-phase electricity is used, with a rated current of approximately 32A. However, please note that the actual current may vary depending on the manufacturer and equipment type. It is recommended to consult the specifications of the relevant equipment or contact the manufacturer for detailed information.

2、 Matching 7KW AC charging station with electric vehicles
1. Charging speed: Taking an electric vehicle battery capacity of 60kWh as an example, using a 7KW charging station takes about 8.5 hours to fully charge (60kWh ÷ 7kW=8.57 hours).
2. Supported vehicle models: The 7KW AC charging station is compatible with most mainstream electric vehicles, such as Tesla, BYD, NIO, etc. As long as the vehicle supports 7KW AC slow charging (the on-board charger OBC needs to be matched), this type of charging station can be used.

3、 Installation and usage precautions
1. Power capacity: The total capacity of household electricity meters should be ≥ 40A to avoid tripping caused by simultaneous use with high-power appliances. It is recommended to apply for an independent electricity meter, such as a new energy dedicated meter, and some areas can also enjoy peak and valley electricity price discounts.
2. Line requirements: The cable specification should be ≥ 6mm square copper core wire to ensure safe carrying of 32A current. If the line is too long or old, it may be necessary to upgrade the line or increase the diameter of the line.
3. Installation location: It can be installed indoors or outdoors, but when installing outdoors, a charging station with an IP54 or higher protection level must be selected to ensure dust and water resistance. At the same time, it is recommended that the installation location be ≤ 5 meters away from the parking space to reduce cable loss.
4. Energy saving and compatibility: By using the "scheduled charging" function, charging can be done during lower electricity prices in the valley at night, saving costs. In addition, regularly cleaning the charging gun interface can maintain good conductivity. Before installation, it is necessary to confirm the electrical conditions and vehicle compatibility, and choose a reliable brand.

In summary, the 7KW AC charging station has a wide range of applicability and high cost-effectiveness, making it one of the preferred choices for household charging. When selecting and using, attention should be paid to its power, current, and compatibility with electric vehicles, and relevant installation and usage precautions should be followed.
