Once you become an electric car owner, what follows, usually, is the question of the battery’s longevity. In general, this main component of a thermic vehicle is replaced every 5 years, while that of an electric vehicle is replaced every 6 to 13 years. This range varies depending on the daily use of the car.
If you would like to learn more about how to take care of your electric battery, discover all our tips to put in place in your daily routine :
If you want to know the health state of your electric battery, verify its SoH (State of Health). This is a detailed description of the traction battery’s control*. Its result is shown in percentage and indicates the degree of degradation of the battery compared to its initial performance (power and autonomy loss). It is possible to make the diagnostic using tools sold online or use the services of a professional (dealership, manufacturer or repair shop). The price varies between 50 and 130€.
Now you know the SoH of your battery, the goal is to conserve the percentage of degradation at the lowest level and for the longest time possible. How to do that ?
The batteries do not like to be charged at 100% of their capacity. The ideal charge range is 20 to 80%.
Also, it is preferable to prioritize short charging sessions rather than longer sessions, which heat the battery too much.
Even if it is practical, the supercharger can damage your battery, especially if you use it frequently. A slow charge preserves the battery’s components and its longevity.
Also, charging in the evening at your place can be a good practice !
The batteries are sensitive to large temperature changes. In fact, under very strong or very weak heat, the battery’s components become unstable which causes a fast energy loss !
We therefore advise you to leave your car in an area with average and stable temperatures (over 5° C and under 27° C). A garage is thus ideal ! This will also allow a lower consumption for defrosting, heating and air conditioning.
You know now the different tips that allow you to prolong the longevity of your electric battery. However, be aware that even if you take care of your car and its battery, the autonomy and performance of the two always end up diminishing over time.
