Charge Mode

The BCM will enter Charge Mode when ever one of the following conditions are met:

• The headlamps are ON, low or high beam.
• The wipers are ON for more than 3 seconds.
• The electric cooling fans are on high speed for more than 1 minute and either fluid head pressure is greater than 1600 kpa (232 PSI) or engine coolant temperature is greater than 105°C (221°F).
• The rear defogger is ON for more than 1 minute.
• The HVAC front blowers are on high speed for more than 1 minute and estimated battery temperature is greater than 32°C (89°F).
• The estimated battery temperature is less than 0°C (32°F).
• Battery SOC is less than 80 percent.

Once one of these conditions is met, the generator battery control module will set the targeted generator output voltage to a charging voltage between 13.9 volts and 15.5 volts, depending on battery SOC and estimated battery temperature.
