Battery And Cables (G2749057): Operation: Notes

The PHEV  battery stores the electrical energy from the following:

• The PHEV  battery onboard charger (In the High Voltage Integrated Box)
  • For additional information, Refer to: HIGH VOLTAGE INTEGRATED BOX
• The CIMG  during regenerative braking controlled by the inverter.

The PHEV  battery also delivers electrical energy to the following:

• The CIMG  controlled by the inverter
  • For additional information, Refer to: INVERTER
• The HV  interior heater
  • For additional information, Refer to: HEATING AND VENTILATION
• The electric A/C  compressor
  • For additional information, Refer to: AIR CONDITIONING
• The vehicle 12V electrical systems through the DC/DC  (In the High Voltage Integrated Box).
  • For additional information, Refer to: HIGH VOLTAGE INTEGRATED BOX

The BECM  controls the HV  energy both delivered and supplied by the PHEV  battery. The BECM  may restrict the amount of energy delivered or supplied if the PHEV  battery internal temperature is outside the normal operational temperature range.

The BECM  also controls the temperature of the PHEV  battery. The PHEV  battery temperature control operates when the vehicle is driven. The PHEV  battery temperature control also operates while the PHEV  battery onboard charger is connected to an external power supply by the charging port.

The BECM  monitors the individual PHEV  battery cell voltages when the vehicle is in operation or the PHEV  battery is charging. It compares the PHEV  battery cell voltages and adjusts them based on a delta voltage difference. If the vehicle is not to be used for an extended period of time, connect the vehicle to an external power supply. This will maintain the PHEV  battery State Of Charge (SOC) at a high level.
