Surprise: EV batteries are tougher than you think

New data from over half a million real-world tests shows electric vehicle batteries are holding up much better than many people feared. An independent diagnostics company, Aviloo, analyzed the battery health of 20 popular EV models from brands like Tesla, Volkswagen, Hyundai, and Nissan. They used a standardized 3-minute test via the car's diagnostic port to measure the battery's State of Health, giving a more accurate picture than the car's own dashboard readings.

The results are encouraging for both current EV owners and the used car market. After racking up 150,000 kilometers, most tested vehicles still retained around 90% of their original battery capacity. Even the worst-performing models weren't far behind. This data from across multiple continents suggests that the common fear of rapid battery degradation and crippling replacement costs may be overblown. The takeaway is that EV batteries are proving to be durable, reliable components built to last the life of the car.
