Battery Charger

The hybrid battery charger is a serviceable assembly containing several micro-processors, two separate high voltage chargers and a single low voltage charger. It is mounted behind the passenger's side headlamp assembly and is flash programmable, communicating on both GMLAN and the High Voltage Energy Management Expansion bus. Engine coolant (DexCool) is used as a cooling medium to ensure that the charger does not exceed its maximum designed operating temperature. The low voltage charger is used to ensure that the 12 V battery does not become depleted during a charge event, while one the high voltage chargers is used with a 120 V charge source and both are used with a 240 V charge source.
