According to a recent study, electric car batteries last particularly long. We’ll explain it to you.
Many motorists are afraid of switching to electric cars, particularly because they are afraid that their battery will quickly fail and need to be replaced. However, this element is particularly expensive, since it represents around 40% of the total price of a zero-emission car. But now a new study should reassure the most skeptical on the subject.
Electric cars that last
Indeed, the management consulting firm P3specializing in e-mobility, recently published a detailed study on the durability of electric car batteries. By analyzing data from more than 7,000 vehicles, researchers shed essential light on the aging of these key components. Contrary to fears expressed at the start of electric mobility, no massive battery failure has been observed after a few years, even for vehicles that have traveled long distances. The battery, the centerpiece and the most expensive of electric cars, raises many questions about its longevity.
Premature deterioration in its performance would result in high costs for owners, ranging from expensive repairs to complete replacement, not to mention a loss of resale value. It is in this context that P3, in partnership with the specialized startup Aviloo, conducted an in-depth analysis by comparing data from 50 vehicles in its fleet with those from 7,000 other electric cars.
Good news
The results reveal a clear evolution. During the First 30,000 kilometersthe loss of capacity is notable, with a state of health (SoH) which drops from around 100% to 95%. However, beyond this point, the degradation slows down considerably. At 100,000 kilometers, the batteries retain an average of 90%. of their initial capacity Even more impressive, between 200,000 and 300,000 kilometers, the SoH remains stable, well above the thresholds guaranteed by the manufacturers (generally). between 70% and 80%).
Moreover, and to allay users’ concerns, manufacturers today offer extended warranties on batteries, often covering eight years or 160,000 kilometers, with a guaranteed capacity of 70 to 80%. These measures aim to strengthen confidence in this technology, while supporting the energy transition, while major authorities want to focus on electric cars. Furthermore, the study also highlights a challenge linked to vehicles having traveled more than 200,000 kilometers: the reduced number of examples available.
This limitation leads to greater dispersion of the data, making the analysis less precise for very high mileages. Nevertheless, the available data, from various manufacturers and usage profiles, confirm the robustness of electric batteries under intensive use conditions. P3 experts emphasize the importance of providing transparent and reliable data to allay fears related to electric mobility. A better understanding of real-world battery performance will help increase social acceptance of electric cars.
