MHEV Battery Stored Energy Usage

The electrical energy produced by the BISG  is stored in the MHEV  battery and is used by the following:

• The BISG  for the engine auto stop/start operation.
  • For additional information, Refer to: BELT INTEGRATED STARTER GENERATOR
• The BISG  to provide engine assist when requested by the PCM  , to reduce fuel consumption and exhaust emissions.
• The DC/DC  to supply the 12V systems and to charge the startup battery. The DC/DC  is controlled by the BCM/GWM.
  • For additional information, Refer to: DIRECT CURRENT TO DIRECT CURRENT CONVERTER
  • For additional information, Refer to: STARTUP BATTERY AND CABLES - INGENIUM I6 3.0L PETROL 
• The electric supercharger to supply air to the turbocharger. The electric supercharger is controlled by the PCM  .
  • For additional information, refer to: SUPERCHARGER COOLING

When the MHEV  battery State of Charge is less than a specific limit, the auto stop/start is disabled. The auto stop/start disabled warning indicator is also shown in the IPC  .

For additional information, Refer to: BELT INTEGRATED STARTER GENERATOR

If the internal temperature of the MHEV  battery is outside specific limits, the BECM  will restrict the amount of energy which is available.
