Charging slowly with Level 1 or Level 2 charging is probably better for battery health than DC fast charging, but it’s totally fine to use fast charging when you need to.
To keep its battery as healthy as possible for as long as possible, the best way to charge an electric vehicle is frequently, in small amounts, at slower speeds. Using a higher current and charging rapidly is harder on the battery than using a lower current and charging slowly.
That said, EVs are built to handle fast charging and real-world studies haven’t shown battery degradation related to fast charging, though laboratory studies suggest fast charging will speed up battery degradation over the long-term. EVs are designed to serve our needs, not the other way around. If you need to use fast charging, don’t hesitate to do so.
