Still got doubts about the battery lifespan of EV's? Owners have been collecting data for years from all over the World. They make for some very interesting stats. One of the high mileage Tesla's with 358,000 KM, or around 228,000 miles, still has around 94% of it's original range after a full charge.
Assuming an EV needs 80% of it's original capacity to work properly (is that the case with a Tesla pack too?) then the battery is only a third of it's way through it's life after 228,000 miles. Obviously different charging patterns, climates and deterioration over age are going to give varied results, but it's a promising proposition so far.
