One of the most common questions that arise for those considering buying an electric car is related to the service life of its battery. After all, the traction battery is the most expensive part of an electric car, and its resource directly affects the residual value of the car and long-term operating costs. How many years or kilometers will it last? Let's figure out this issue. Also, you can improve your car and improve its functionality by using tuning accessories, a huge selection of which is available in our product catalog.

Average battery life

Most manufacturers guarantee that an electric vehicle battery will last:

8-10 years. This is the standard warranty period for most models, such as Tesla, Nissan Leaf or BMW i3.
100,000-150,000 km of mileage. After this, the battery may lose 20-30% of its capacity, but will remain usable.
Longer with proper use. Some batteries last 15 years or more with proper care.

What does the actual service life depend on?

The actual battery life may significantly exceed the warranty obligations and depends on many factors:

Climate: Extremely high (heat) or low (frost) temperatures negatively affect the battery and can accelerate degradation.
Charging Mode: Frequent use of high-power fast charging (DC) can be more stressful on the battery than slow charging (AC). Constant charging to 100% is also considered less optimal for longevity than charging to 80%.
Driving style: Aggressive driving with sharp acceleration and intensive regenerative braking places increased stress on the battery.
Mileage: The number of charge-discharge cycles directly affects the residual capacity.

The battery does not "die" at one point

It is important to understand that the battery does not "die" suddenly, like a regular battery. Its resource is exhausted gradually: over time and the number of charge-discharge cycles, its maximum capacity decreases. Even after the warranty period expires, the battery will most likely function, but the range of the electric vehicle may decrease. Operating experience shows that many batteries remain functional even after 10 years or 200+ thousand kilometers.
