Demystifying Electric Car Battery Longevity, Degradation, and Peace of Mind for Future Owners.
How Long Do Electric Car Batteries Actually Last?
Decoding EV Battery Lifespan: Beyond the Myths When we talk about electric car battery life, we're discussing its ability to consistently store and deliver energy over time. Like any rechargeable technology, EV batteries do experience degradation, a gradual reduction in their maximum capacity and performance. However, this process is meticulously managed and surprisingly slow in today's advanced lithium-ion battery packs. The Reality of Degradation: A Slow Burn, Not a Sudden Drop Understanding the Annual Capacity Loss Contrary to the myth of sudden battery death, EV batteries degrade gradually. Extensive real-world studies, such as those conducted by Geotab across thousands of vehicles, consistently show an average annual degradation rate of approximately 2.3% . This means that after five years, an EV battery might have lost around 10-12% of its original capacity, still leaving 88-90% for use. Even after a decade, many batteries retain 75-80% of their initial range. This slow rate e…
