Care and maintenance -> 12 V battery for Your Volvo EX30 4 Door First Generation (2025-2026)

During warmer periods of time, you're recommended to plug in the car during parking. High temperatures cause battery dam-  
age, especially when the car is exposed to hot weather for prolonged periods. The car can actively cool the battery while it's  
parked, but that uses power. When you're returning to your parked car, the battery level could be noticeably lower than before. If  
the car is plugged in for charging, it can cool the battery without lowering the battery level and risking a flat battery.  
In hot temperatures, it is recommended that you park in a shaded spot. Strong sunlight combined with high temperatures can  
lead to very high battery temperatures and excessive cooling needs.  
Parking in cold weather  
When the battery is cold, the car temporarily reduces battery performance until it's warmed up. Driving the car in a state of re-  
duced performance doesn't harm the battery.  
To avoid temporarily reduced performance from a cold battery, connect the car for charging and activate the car's precondition-  
ing ahead of your trip. The car can then heat the battery without affecting performance and available range.  
In temperatures below -30 °C (-22 °F), avoid leaving the car parked without charging for longer than 24 hours.  
13.5.1.2. Powertrain cooling system  
Your car has an advanced temperature regulation system.  
The system actively regulates the temperature of the traction battery while you're parked, charging or driving your car. This hap-  
pens if your car experiences high or low temperatures and during preconditioning.  
Important  
Never attempt to add coolant yourself  
The cooling system is a closed system. A trained technician must perform any required maintenance of the cooling sys-  
tem.[1]

Volvo recommends an authorised Volvo workshop.  
13.5.2. 12 V battery  
The 12 V battery powers everything in your car except the electric propulsion.  
Servicing and replacement  
The 12 V battery is maintenance-free.  
Contact an authorised Volvo workshop if the 12 V battery needs to be replaced.

Important  
12 V terminal  
In the event of a total loss of power, your car can't be unlocked as the locks are electrically operated. To access your car  
and charge it, it can be powered for a short time using the externally accessible 12 V terminal. The terminal can be ac-  
cessed by removing a small panel below the front bumper, near the front left wheel.  
Before any use of the 12 V terminal, consider the following:  
Volvo recommends that the 12 V terminal is only used by service technicians for the purpose of accessing the car as  
part of immobilisation recovery.  
The external 12 V terminal on your car should only be used to make your car accessible. Do not attempt to charge  
another car or similar external source from this point.  
Only use a 12 V charger with a maximum charging current below 40 A.  
Connecting any power source that delivers currents higher than 40 A blows the terminal's fuse, thereby disabling it.  
Only use the 12 V terminal for short amounts of time. This is not meant as a way of powering the car continuously.  
Make sure to follow the positive and negative markings on the terminals as reversing the polarity of the low voltage  
system can lead to damaging the low voltage system components or blowing the 40 A fuse.
