High Voltage Battery (lithium-ion battery)

The charge amount of the high voltage battery may gradually decrease when the vehicle is not being driven.
The battery capacity of the high voltage battery may decrease when the vehicle is stored in high/low temperatures.
Distance to empty may vary depending on the driving conditions (such as outside temperature), even if the charge amount is the same. The high voltage battery may expend more energy when driving at high-speed or uphill. These actions may reduce the distance to empty.
The high voltage battery is used when using the air-conditioner / heater. This may reduce the distance to empty. Make sure to set moderate temperatures when using the air-conditioner/heater.
Natural degradation may occur with the high voltage battery depending on the number of years the vehicle is used. This may reduce the distance to empty.
When the charge capacity and distance to empty keep falling, contact an authorized HYUNDAI dealer for inspection and maintenance.
If the vehicle will not be in use for an extended period of time, charge the high voltage battery once every three months to prevent it from discharging. Also, if the charge amount is not enough, immediately charge to full and store the vehicle.
To keep the high voltage battery in optimal condition, use AC charging. Fully charging the high voltage battery when it is 20 % or lower helps keep the battery in optimal condition. (Charging once a month or more is recommended.)

If the vehicle is kept with insufficient charge for a long period, it may damage the high voltage battery and the high voltage battery may have to be replaced depending on the level of degradation.
If the vehicle is in a collision, contact an authorized HYUNDAI dealer to inspect whether the high voltage battery is still connected.
Using the V2L function may reduce the mileage due to the use of high voltage battery energy, and repeated use of the V2L function may cause a decrease in the life of the high voltage battery.
