High-voltage battery

High-voltage battery

For propulsion using the electric motor, the vehicle is equipped with a battery located underneath the vehicle. It is a maintenance-free and rechargeable lithium-ion battery.

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 charged. 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.


High-voltage battery replacement may only be performed by a workshop – an authorized Volvo workshop is recommended.

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 0%.
  • 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.
