Tesla Model S battery pack data shows very little capacity loss over high mileage
‘Lithium’ battery capacity degradation is one of the main concerns of electric vehicle buyers and potential buyers. Since the resurgence of electric cars is relatively recent, meaningful long-term data on large battery packs is fairly rare. Only Tesla has battery packs with a capacity higher than 30 kWh on the road in any significant number and they only have been in operation for a few years (Roadster aside).
But a few Tesla owners have accumulated impressive mileage on their vehicles and the data provides an interesting look into potential battery capacity degradation. Expand
