High-voltage battery

Your Polestar is equipped with a high-voltage battery located in the vehicle's chassis. It is maintenance-free and rechargeable.

Only authorized workshop personnel may handle high-voltage components.

If the high-voltage battery is discharged, it will not be possible to start the vehicle. If both the 12 V battery and the high-voltage battery are discharged, both batteries must be recharged. In this situation, it is not possible to first charge only the high-voltage battery. The 12 V battery must have a certain charge level in order for the high-voltage battery to be charged.

 Warning

Only a workshop may replace a high-voltage battery – contact Polestar Customer Support.

High-voltage battery service life and capacity

The capacity of the high-voltage battery decreases with age and use, which could result in decreased range.

Here are some recommendations for increasing the battery's service life:
  • Plug in the charging cable when the vehicle is parked. Especially in very hot or cold weather.
  • Avoid discharging the battery completely to low charge levels.
  • If the charge level is 0%, the battery should be recharged as soon as possible.
  • Avoid fully charging the battery to the maximum level unless needed for the distance you will drive. A recommended charge level is shown in the center display.
