A six-month-old Model Y showed 99% battery health after 16,000 miles.
The owner used more DC fast charging than AC charging over a six-month period.
Careful charging habits may matter more than avoiding fast chargers entirely.
Frequent fast charging is a documented way to accelerate electric vehicle battery degradation. But you can mitigate some of its negative impact by not charging to 100% and never letting the battery run down below 20% state of charge.
Battery degradation experts have also found that the rate at which an EV pack loses capacity is highest when it’s new, and then it gradually tapers off. So how much capacity do you think a six-month-old Tesla Model Y has lost after covering 16,000 miles and seeing more fast charging than Level 2 home charging?
