In addition to electric propulsion, the hybrid battery is also used to start the gasoline engine. The vehicle can therefore not be started if the battery has for any reason become discharged. To charge the hybrid battery, the vehicle's smaller 12 V battery must also have sufficient charge to power the vehicle's electrical system and start charging.
Warning
Hybrid battery replacement may only be performed by a workshop – an authorized Volvo workshop is recommended.
Hybrid battery service life and capacity
The capacity of the hybrid battery decreases with age and use, which could result in increased use of the combustion engine and thereby higher fuel consumption and reduced electric motor range.
Coolant
The hybrid battery's cooling system has its own expansion tank.
Important
Filling the hybrid battery coolant should only be performed by a workshop – an authorized Volvo workshop is recommended.
