The hybrid/EV powertrain control module 1 within the T6 power inverter module monitors system high voltage.
The hybrid/EV battery pack contains 3 high voltage contactors. The high voltage contactors allow the high voltage DC to be connected to the vehicle or safely contained within the hybrid/EV battery pack. The high voltage contactors consist of a main positive high voltage contactor, main negative high voltage contactor, and a precharge negative high voltage contactor.
