The PHEV battery onboard charger is located under the floor pan between the front and rear axle on the left side.
The PHEV battery onboard charger is cooled by the engine coolant system. The high voltage cooling system has an electric coolant pump controlled by the Electric Power Inverter Converter (EPIC) to circulate the engine coolant. An inlet and outlet pipe are connected to the cooling system to allow the circulation of engine coolant through the PHEV battery onboard charger.
The PHEV battery onboard charger has a pressure equalization pipe connected to the body and the other open end mounted high in the engine compartment. This allows for the equalization of pressure between the inside and outside of the PHEV battery onboard charger.
The PHEV battery onboard charger has 5 electrical connections. These are for:
- A high voltage Direct Current (DC) cable connected via the High Voltage Junction Box (HVJB) to the PHEV battery.
- A high voltage Alternating Current (AC) cable to the charging port.
- The 3 wiring harness 12 pin connectors provide connections for these:
- A 12V supply.
- The High Speed (HS) Controller Area Network (CAN) power mode zero systems bus (2 off).
- The high voltage interlock loop (2 off).
- The charging port plug lock (3 off).
- The charging port plug lock ground.
- The charging port temperature connection (2 off).
- The charging port external connection.
- The charging port ground connection.
- The charging port Light Emitting Diodes (LED) display 3 colors (3 off).
- The charging port LED display ground.
- A ground connection.
