Ford Fusion: Charging System - General Information / Charging System - Overview. Description and Operation
Overview
The generator is driven by the FEAD belt. When the engine is started, the generator begins to generate AC voltage which is internally converted to DC voltage. The DC voltage level is controlled by the voltage regulator (located on the rear of the generator) and is supplied to the battery. The PCM works with the generator internal voltage regulator over two communication circuits, GENMON and GENCOM to control the voltage regulator setpoint.
This vehicle is equipped with load shed strategy. The BCM monitors the battery state of charge using the battery current sensor attached to the negative battery cable. The PCM monitors the generator current using the generator current sensor attached to the generator B+ battery cable. The PCM uses the information supplied from the generator current sensor to adjust the engine idle stability and torque control.
