Understanding the Warning Lights and Indicators in Electric Vehicles

How To understand EV warning lights and indicators

01. Ready indicator light:
The indicator lights up when the electric vehicle is in a drivable state. If there's an issue with the vehicle's systems, the indicator will turn off or blink.

02. Power down warning light:
The indicator lights up when the vehicle's output is limited to protect high-powered parts or when the remaining power of the driving (high-voltage) battery is very low, or the voltage is getting low. When the light is on, going up hills may be difficult, or the vehicle may roll backward. If only the power down warning light turns on, it doesn't mean a failure occurred.

03. Charging indicator light:
The light turns on when the charging connector is properly connected to charge the high-voltage battery of an electric vehicle.

04. Regenerative brake warning light:
The lights illuminates yellow if regenerative braking doesn't work well due to a brake system disorder and brake performance is slightly reduced.

05. High voltage battery level warning light:
The light turns on when the remaining power of the high-voltage (drive) battery is low. When the warning light turns on, charge the battery immediately.

06. Battery conditioning mode indicator light:
The indicator lights up when the battery conditioning mode is active.

07. Service warning light:
The light displays when there's a failure related to the electric vehicle control system such as sensors.
