What are the safety protection measures for 7KW AC charging piles?

The safety protection measures for 7KW AC charging piles mainly include the following aspects:

1、 Physical security protection
The installation location of the charging station should be away from flammable and explosive materials, avoid exposure to rain, and be firmly fixed to prevent accidents.
The shell and junction box of the charging station need to have waterproof and moisture-proof functions to ensure safe use in harsh weather conditions.
3. Equipped with anti-collision and anti-theft measures to enhance the durability and safety of the charging station.

2、 Electrical safety protection
1. The circuit system needs to have good insulation protection to prevent the occurrence of leakage accidents.
2. The charging station is equipped with multiple protection mechanisms, including temperature, voltage, current, leakage, emergency stop, short circuit and other protection functions. For example, overvoltage protection will automatically shut down when the voltage exceeds a certain threshold, while overcurrent protection will quickly cut off the power supply when the current is abnormal, ensuring the safety and stability of the charging process.
3. The leakage protection switch is an important component of the charging station. For a 7-kilowatt charging station, it is recommended to choose a leakage protection switch with a rated current of 21 kilowatts or more to ensure that the power can be cut off in a timely manner in case of leakage.

3、 Environmental adaptability protection
1. Charging stations need to have temperature monitoring function to take corresponding protective measures when the temperature is too high or too low.
In thunderstorm weather, charging stations should be equipped with lightning protection, such as lightning protection devices, to prevent damage to charging stations and charging equipment caused by lightning.

4、 Operation and maintenance safety
1. The use of charging stations should follow the operating instructions to avoid safety hazards caused by abnormal operations. For example, do not charge in rainy or humid environments, and do not modify charging stations without authorization.
2. Regularly maintain and inspect the charging station, including checking the cables, sockets, and the charging station itself, replacing worn lines and damaged components in a timely manner to ensure the normal operation and safe use of the charging station.

In summary, the 7KW AC charging station has taken various measures in terms of safety protection, including physical safety protection, electrical safety protection, environmental adaptability protection, and operation and maintenance safety, to ensure the safety of users during the charging process.
