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, have your vehicle 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.

  • Frequent use of DC charging may impact battery life.

  • 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 on highway at high speeds or uphill will increase battery consumption, resulting in a shorter distance to empty.

  • If you use the air conditioner or heater, which is powered by the high voltage battery, the distance to empty will be reduced. Maintain reasonable temperature when using the air conditioner or heater to maximize distance to empty.

  • Depending on the vehicle's period of use, natural degradation of the battery may occur that reduces distance to empty over long period of vehicle life. When the charge capacity and distance to empty keep failing, have your vehicle inspected by an authorized HYUNDAI dealer.

  • If you do not use the vehicle for a long time, charge the vehicle at least once every three months to prevent both the high voltage and the 12 V battery from fully discharging. When the battery level has low level, immediately charge the vehicle.

  • Using AC charging as much as possible can help keep the battery in optimal condition. 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.
