The hybrid battery charger receptacle is connected to the battery charger through two 110/220 V AC circuits and one earth circuit. The battery charger receives a serial data message from the hybrid powertrain control module 2 that the drive motor battery charger cable has been connected and then monitors the two 110/220 V AC circuits for proper voltage.
