Ford Escape: Charging System - General Information / Description and Operation - Charging System - 1.5L EcoBoost (132kW/180PS) – I3 (Y1) - 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 is controlled by the voltage
regulator and supplied to the battery. The PCM controls the voltage
regulator set point, communicating with the generator internal voltage
regulator over a 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.
