Tesla’s latest 2022 impact report shows that its car battery only decays by 12% after driving 200,000 miles. The life of the battery is directly related to the life cycle of the vehicle, which in turn has an impact on the sustainable development of the environment.
However, Tesla only mentioned the battery decay problem of Model S and Model X, probably because these two models have more long-term data as a reference. Interestingly, Tesla also said it would start disclosing additional data on new battery chemistries used in more recent vehicles:
Range is only one factor in battery capacity retention; battery life is also a major factor. The lower mileage retention figures above may reflect the effect of vehicle age, while those vehicles with higher utilization may be less affected. Performance of new chemicals (not mentioned here) may vary and we plan to expand the disclosure when sufficient data becomes available.
Simply put, due to different models and battery sources, this attenuation phenomenon also has great differences. In addition, according to statistics from foreign media Electrek, Tesla’s 90 kWh battery pack decays significantly faster than the 85 kWh battery pack.
The early data of Tesla Model 3 and Model Y also show that the battery capacity decay rate of the new car is less than 10% after driving 100,000 miles, and the decay rate is less than 15% after 200,000 miles. There are not many models.
Of course, you don’t have to worry too much, this data is also kept within the guaranteed capacity of Tesla’s battery warranty.
