Description

In normal charge, the battery is charged through the On-Board Charger (OBC) using external power
supply of 220V.

On-Board Charger (OBC) is the equipment that charges the high voltage battery of electric vehicle
using the 110 - 220V AC power.

Main Function

Removal

Warning

• Be sure to read and follow the "General Safety Information and Caution" before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.
• Be sure to read and follow the "High Voltage Shut-off Procedures" before doing any work related with the high voltage system. Failure to follow the safety instructions may result in serious electrical injuries.

1. Turn ignition switch OFF and disconnect the negative (-) battery cable.
2. Shut off the high voltage circuit.

    

   (Refer to Hybrid Control System - "High Voltage Shutoff Procedure")

3. Drain the coolant by loosening the drain plug.

    

   (Refer to Hybrid Motor System - "Coolant")

4. Remove the LH front wheel & tire and wheel house cover.
5. Remove the front bumper assembly.

    

   (Refer to Body - "Front Bumper Cover")

6. Disconnect the OBC cable connector (A).
