Frequently asked questions about charging time
Why does charging sometimes take longer than the calculator says?
Above roughly 80% battery level, almost every car slows down charging to protect the battery. The last 20% can therefore take longer than all the rest combined. Cold batteries also charge more slowly.
What is an on-board charger (OBC) and why does it matter?
The on-board charger converts AC power from a regular charging station into DC for the battery. Even on a powerful AC station, your car can never charge faster than its own on-board charger allows.
How much charging loss should I count on?
Count on roughly 10 to 15% loss when charging on AC, mainly from conversion in the on-board charger and heat. With fast charging (DC) the loss is usually lower because the conversion already happens in the station.
