Electric operation and charging

Hybrid battery

Updated 11/26/2021

Hybrid battery

The hybrid battery powers the car's electric motor and is charged via the car's charging input socket.


The car cannot be started if the hybrid battery is discharged.

If both the starter battery and the hybrid battery are discharged then both batteries must be charged. In such a case, charging only the hybrid battery is not possible. In order for the hybrid battery to be charged, the starter battery must have a certain state of charge.


The hybrid battery must only be replaced by a workshop - an authorised Volvo workshop is recommended.

The service life and capacity of the hybrid battery

The capacity of the hybrid battery diminishes with age and use, which may result in increased use of the internal combustion engine and, as a consequence, reduced fuel economy and reduced range during electric operation.


The hybrid battery's cooling system has a separate expansion tank.
