Ford Escape: High Voltage Battery Charging System - Plug-In Hybrid Electric Vehicle (PHEV) / Description and Operation - High Voltage Battery Charging System - Plug-In Hybrid Electric Vehicle (PHEV) - Overview

Overview

The high voltage battery charging system is responsible for charging the high voltage battery while the vehicle is not operating. It consists of an Electric Vehicle Supply Equipment (EVSE), SOBDM and Charge Status Indicator (CSI).

The EVSE is an external AC charger that connects to an external voltage source and the vehicle charge port when the vehicle is not operating to charge the high voltage battery. The 110V (AC Level 1) charger and cord set plugs into a standard 110V AC outlet and comes with the vehicle when purchased. The 110V charger is rated up to 12 amps or up to 16 amps depending on the household receptacle being used. It is recommended to use a dedicated 110V electrical outlet to ensure adequate current supply for charging. A 220V ( AC Level 2) charging station can also be utilized which is rated up to 80 amps.

The SOBDM , also known as the Battery Charger Control Module (BCCM), is a liquid cooled component that charges the high voltage battery when the vehicle is not operating and plugged into a (110V or 220V) EVSE. The SOBDM is known as the on-board charger. Its primary function is to coordinate charging operations and convert AC to DC . The SOBDM incorporates an integrated module that communicates with other modules over the HS-CAN .

When the EVSE is plugged into the vehicle charging port the CSI (Charge Status Indicator) indicates the current Customer State-of-Charge (CSoC) and charging operations of the high voltage battery. The CSI is a light ring surrounding the charge port inlet that displays charging, charging faults and charging status using five LED light segments. The CSI is connected to the SOBDM and controlled using a LIN communication circuit.
