Application of Dc contactor in new energy vehicle and charging pile

1 Application in charging pile

Used for dc charging pile, dc output side of charging station or output side of vehicle charging machine. When the contactor closes, it connects the charging pile with the car, When the contactor disconnected, charging pile is isolated from the external connection, and play the role of safety protection.

 2. Applications in electric vehicles

The dc contactor provided between the battery system and the inverter of the electric vehicle. When the system stops running, it acts as isolation, and the system is connected at running time, When the vehicle stops or breaks down, the energy storage system can be safely separated from the vehicle electrical system, It acts as a circuit breaker. As an electrical control device in other auxiliary circuits.

Key technical indicators:

a) After the system stops running, it will isolate the power supply from the load.( Key technical indicators: Rated voltage / Ui )

b) When the system is running, it connects the power supply and the load. ( Key technical indicators: Conventional thermal current / Ith )

c) In a failure, It acts as a circuit breaker. ( Key technical indicators: Maximum working voltage/ U )
