Precautions when using the high voltage battery

Precautions for high voltage battery when driving and storing the vehicle are as follows:

  • Keep the gauge of the high voltage battery from going below than 10 %. Storing the vehicle while the battery level is low for a long time may damage the battery or reduce the battery's capacity, potentially causing the need for a battery replacement.

  • If a collision occurs and the vehicle is impacted, we recommend that your vehicle be inspected by an authorized HYUNDAI dealer to check the battery connection status.

  • Using the V2L function may reduce the driving distance due to the use of the high voltage battery energy, and repeated use of the V2L function may cause a decrease in the life of the high voltage battery.

  • Repeated use of a DC charger may cause a decrease in the life of the high voltage battery.

  • The high voltage battery level may reduce naturally even if the vehicle is not driven.

  • Storing the vehicle in temperatures that are too hot or cold may degrade the battery performance.

  • The distance to empty or power output may vary depending on the driving conditions, such as the outside temperature. Driving at high speeds or uphill may increase battery consumption, resulting in a shorter distance to empty.

  • If you use the air conditioning or heating, which is powered by the high voltage battery, the distance to empty may decrease. Maintain proper temperature when using the air conditioning or heating.

  • Depending on the vehicle's period of use, natural degradation of the battery may occur, so the distance to empty may decrease. When the charge capacity and distance to empty keep failing, we recommend that your vehicle be inspected by an authorized HYUNDAI dealer.

  • If you do not use the vehicle for a long time, charge the vehicle at least once every 3 months to prevent the battery from fully discharging. When the battery level has lower power, immediately charge the vehicle.

  • To keep the battery in optimal condition, use AC charging. Fully charging the battery when it is 20 % or lower helps to keep the battery in optimal condition. (Charging once a month or more is recommended.)

  • The charging level value displayed on the instrument cluster may decrease according to the charging conditions (charger status, outside temperature, battery temperature, etc.). For longer battery life and safety, after a certain charging level is reached, the charging current is gradually lowered to fully charge the battery.
