Submission + - Real-Life Tesla Study Shows Durability of EV Batteries
Rutabaga8 writes: A recent study of 7 years’ worth of data shows how well Tesla batteries actually hold up. Consumer research site NimbleFins analysed data from Plug In America for Model S cars and found some surprising results.
By seven years of age, the typical car could still deliver around 93% of the original range on a full charge. That means a Tesla battery typically loses around 1 percentage point of range each year on the road.
Of course, cars that put more miles on the odometer are likely to get faster battery deterioration, because it’s the number of charges that really impact battery degradation. However, the data showed that by 150,000 miles Tesla cars still achieved more than 85% of their original range when they were charged to full capacity.
