Charging System - Overview: 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  controls the voltage regulation setpoint, communicating with the generator internal voltage regulator over a dedicated LIN  communication circuit

This vehicle is equipped with load shed strategy. The BCM  monitors the battery state of charge and condition using the battery monitoring sensor attached to the negative battery post and manages battery charging.
