Hybrid Only Gauge

High Voltage Battery Gauge (PHEV, Except China) 

The high voltage battery gauge displays the total percentage of battery charge available associated with electric only driving range. A full fill display indicates the total amount of energy obtained from an external charging source (vehicle plugged in). When the fill display indicates empty, the powertrain system will automatically switch to operating in hybrid mode.

The IPC receives the battery state of charge data message from the GWM over the HS-CAN3. The GWM receives the battery state of charge data message from the BECM over the HS-CAN1.
