Charge Mode

The BCM will enter Charge Mode whenever one of the following conditions is met:

• The interpreted fuel rate is greater than 21 g/s and the throttle position is greater than 90 percent.
• The headlamps are ON, low or high beam.
• The wipers are ON for more than 8 seconds.
• The electric cooling fans are on high speed.
• The rear defogger is ON.

Once one of these conditions is met, the generator battery control module will set the targeted generator output voltage to 13.4 volts and then ramp that voltage up to 14.5 volts at a rate of 50 mV per second.
