Managing battery health and performance
Low battery level and flat battery
Important
High state of charge
Important
For regular charging, battery wear can be reduced by selecting a target battery level lower than 100%. Only charge to 100% if the full range is needed for your next trip.
If you are leaving the car plugged in for charging without any immediate plans to drive it, select the target battery level recommended 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 40-60%. 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 charging limit to 50%. This is for better battery health.
Regularly check the battery level and that charging is working.
Parking in hot weather
Important
During warmer periods of time, you're recommended to plug in the car during parking. High temperatures cause battery damage, 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 reduced 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 preconditioning 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.
