High Voltage (HV) Battery (lithium-ion polymer)
The charge amount of the HV battery may gradually decrease when the vehicle is not driven or charged.
The battery capacity of the HV battery may decrease over time when the vehicle is stored in high temperatures and temporarily in low temperatures.
Distance to empty may vary depending on the driving conditions (cargo, rain, snow, wind, road surfaces), even if the charge amount is the same. The HV battery may expend more energy when driving a fast pace 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 and/or use the pre-conditioning prior to departures.
Natural degradation may occur with the high voltage battery depending on the number of years the vehicle was used and/or the number of charging cycles. This will reduce the distance to empty over time.
When the charge capacity and distance to empty keep falling, have your vehicle checked by an authorized Kia dealer.
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.
AC charge is recommended to keep the high voltage battery in optimal condition.
If the HV battery is only charged to 80%, and you minimize the number of HV battery charging, you can keep the HV battery performance in optimal condition. (vs charging the HV battery to 100% an/or charging every drive cycle.)
-
Make sure to use a designated charger when charging the HV battery. Using different types of chargers may have a serious impact on vehicle durability.
-
Make sure that the HV battery charge gauge does not reach E (Empty). If the vehicle is kept at E (Empty) 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 Kia dealer to inspect whether the high voltage battery is still connected.
The high voltage battery warmer system operates when the charging connector is connected to the vehicle.
However, the high voltage warmer system may not operate when battery temperature drops below -35 °C (-95 °F).
