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.
