The role of DC contactors

1. Application in charging pile (machine)

It is used for the DC charging post, the DC output side of the charging station or the output side for the on-board charger. When the contactor is closed, the charging pile and the automobile are connected; when disconnected, the connection between the charging pile and the outside is isolated to provide a safety protection function.

2. Application in electric vehicles

A DC contactor is disposed between the battery system of the electric vehicle and the inverter. When the system stops running, it acts as an isolation function. When the system is running, it acts as a connection. When the vehicle is shut down or fails, the energy storage system can be safely separated from the vehicle electrical system and function as a breaking circuit. Used as a power control device in other auxiliary circuits.
