Care and maintenance -> Managing battery health and performance for Your Volvo EX30 4 Door First Generation (2025-2026)

13.5.1. Traction battery  
Your car's traction battery is the central power source for your car. It powers all electric propulsion and  
indirectly powers the rest of the car by keeping the smaller 12 V battery charged.  
The traction battery sits low in the underbody of the car.  
Battery care and health  
How you use your car affects the traction battery's condition. Over time its capacity decreases. There are recommended user  
practices that can help extend the battery's service life. These user practices cover events and conditions that can cause battery  
damage.  
Important  
Leaving the car with a low battery level can lead to battery damage. Make sure to charge the car as soon as possible if the  
battery level is near empty.  
Tip  
There are separate sections in this manual about battery health and what you can do to recover from a low-power  
scenario.  
Battery service and maintenance  
The traction battery is a high-voltage component that only authorised technicians are equipped to service safely.  
Warning  
Do not handle or modify the car's electrical components. Only perform actions that are clearly described in the user  
manual.  
High-voltage components can produce or conduct lethal currents and must only be handled by authorised  
technicians.  
Do not perform repairs on the car's electrical system or components. Contact an authorised Volvo workshop for any  
required repairs or servicing.  
13.5.1.1. Managing battery health and performance  
There are user practices that can help maintain the traction battery's condition and performance over time.  
Some scenarios can lead to battery damage and should always be avoided.  
Low battery level and flat battery

instances. For more information, refer to the first page for the complete disclaimer note.  
338 / 396  
Important  
The traction battery can sustain severe damage if it is not charged after the battery level reaches 0%. The car draws a  
small amount of power when parked. Therefore, leaving the car with a low battery level without charging can lead to a flat  
battery and battery damage. If the battery level is below 20% when parked, it is recommended that the car is connected  
for charging as soon as possible.  
If the battery level reaches 0%, the battery is considered flat or empty. The car then needs to be charged as soon as possible to  
reduce the risk of battery damage.  
The smaller 12 V battery is also at risk of going flat if the traction battery can't supply it with power. If both batteries have gone  
flat, the car will have no power at all and no ability to initiate charging.  
High state of charge  
Important  
The traction battery can sustain damage if the car's battery level is kept very high for a long period of time.  
If you are leaving the car plugged in for charging without any immediate plans to drive it, select the target battery level recom-  
mended in the car's charging view.  
Charging habits  
AC charging is the recommended charging mode for everyday charging. This helps maintain the condition of the battery over  
time. DC charging causes more wear.  
Long-term parking  
When leaving your car parked for longer than one month, the recommended battery level is 40ꢀ60%. Use or charge the car to  
reach the recommended level.  
If you are leaving the car parked for longer than three months, it's recommended to keep it plugged in but set the battery char-  
ging limit to 50%. This is for better battery health.  
Regularly check the battery level and that charging is working.  
Tip  
There is a separate section in this manual with more recommendations for long-term parking.  
Parking in hot weather  
Important  
Avoid exposing the car to extreme temperatures. Avoid leaving the car parked for longer than 24 hours if the temperature  
is at risk of reaching 55 °C (131 °F).

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.
