Charging the eleCtriC vehiCle (abrupt stop)
Action to be taken when charging stops abruptly
When the high voltage battery does not charge, check the followings:
1. Check the charging setting for the vehicle. Refer to “Charge Management”, in this chapter (for example, When scheduled charging is set, charging is not initiated
immediately when the AC charger or portable charger (ICCB: In-Cable Control Box)
is connected.)
2. Check the operation status of AC charger, portable charger and DC charger. (Charging Status Indicator Lamp for Portable Charger, refer to “Checking Charging
Status” for trickle charge in this chapter.)

à Actual method for indicating the charging status may vary in accordance with the
charger manufacturer.
3. When the vehicle does not charge and a warning message appears on the cluster, check the corresponding message. Refer to “LCD Display Messages”, in this chapter.
4. If the vehicle is properly charged when charged with another normally working
charger, contact the charger manufacturer.
5. If the vehicle does not charge when charged with another normally working charger, contact an authorized HYUNDAI dealer for inspection.
6. If charging fails and the service warning light (

- The temperature of the high voltage battery is too high or too low
- The temperature of the motor is high
NOTICE
• Do not accelerate or start the vehicle
suddenly when the power down
warning light is ON.
• When the power is limited for the
safety of the high-powered parts of
an electric vehicle, the power down
indicator light illuminates. your
vehicle may not drive uphill or skid
on a slope with the indicator light ON. Charging Indicator Light
This warning light illuminates:
•
When charging the high voltage
battery.
High Voltage Battery Level
Warning Light
This warning light illuminates:
• When the high voltage battery level
is low.
• When the warning light turns ON,
charge the battery immediately.
Regenerative Brake Warning
Light
This warning light illuminates:
When the regenerative brake does not
operate and the brake does not perform
well. This causes the Brake Warning
light (red) and Regenerative Brake
Warning Light (yellow) to illuminate
simultaneously.
In this case, drive safely and have your
vehicle inspected by an authorized
HYUNDAI dealer.
The operation of the brake pedal may
be more difficult than normal and the
braking distance can increase.
