The Power of Balance
The battery power interface functions to connect the battery to the vehicle DC bus as well as implementing safety features required for a high voltage/high power system.
The high voltage electric drive system is isolated from the vehicle chassis. The system includes a ground fault interrupter that disconnects the battery if a current leakage to the vehicle chassis is detected.
The power interface includes:
- contactors that automatically disconnect the battery in case of power system failure or other emergency;
- a high voltage connector with safety interlock;
- a pre-charge system;
- a service disconnect plug;
- a fuse, and
- voltage sensing electronics.
