Ford Escape: High Voltage Battery, Mounting and Cables / General Procedures - High Voltage Battery Charging - Hybrid Electric Vehicle (HEV)

Charging

  WARNING: To prevent the risk of high-voltage shock, always follow precisely all warnings and service instructions, including instructions to depower the system. The high-voltage system utilizes approximately 450 volts DC, provided through high-voltage cables to its components and modules. The high-voltage cables and wiring are identified by orange harness tape or orange wire covering. All high-voltage components are marked with high-voltage warning labels with a high-voltage symbol. Failure to follow these instructions may result in serious personal injury or death.

NOTICE: Follow the detailed instructions included with the Ford approved high voltage battery charger.

NOTE: Check OASIS for any applicable service information before beginning the charging process.

NOTE: High voltage battery packs are typically discharged from an internal combustion engine crank no start symptom or long-term vehicle storage procedures were not followed.

NOTE: The high voltage rescue charger will NOT charge the high voltage battery if the following BECM PID are not within the specified range.

• HEV_BAT_VAR_V PID is less than 2.5V
• HEVBAT_MIN_V PID is greater than 1.45V
• HVBAT_V PID is between 90V and 165V
• H_BATT_TEMP PID is between 0°C and 40°C

1. Depower the high voltage system.
   Refer to: High Voltage System De-energizing (414-03A High Voltage Battery, Mounting and Cables, General Procedures).
   

1. Raise the vehicle on a hoist.
   Refer to: Jacking and Lifting - Overview (100-02 Jacking and Lifting, Description and Operation).
   

1. If equipped, remove the underbody shields to expose the high voltage battery.
   Refer to: High Voltage Battery - Hybrid Electric Vehicle (HEV) (414-03A High Voltage Battery, Mounting and Cables, Removal and Installation).
   

1. Connect high voltage battery charger into an appropriate wall outlet and turn on the high voltage battery rescue charger.
   

1. NOTE: The high voltage battery rescue charger connects directly to the low voltage connector C3733 and high voltage connector C4236D located on the high voltage battery.

   Select the appropriate user Log-in and follow On-Screen prompts to identify vehicle, make cable connections and rescue charge the high voltage battery.
   

1. NOTE: The high voltage battery charger displays the results when charging is completed.

   Follow On-Screen prompts to disconnect rescue charger cables and reconnect vehicle harness connections.
   

1. Turn off the high voltage battery rescue charger and disconnect the high voltage battery rescue charger from the wall outlet.
   

1. If equipped, install the vehicle underbody shields.
   

1. Repower the high voltage system.
   Refer to: High Voltage System De-energizing (414-03A High Voltage Battery, Mounting and Cables, General Procedures).
