A Tesla Supercharger is what’s called a DC fast-charging station. It can charge your car’s battery with up to 150 kW of power. On the original Model S with a 85 kWh battery it would take roughly 20 minutes to charge to 50%, 40 minutes for 80% and 75 minutes for a full charge.
In March 2019 Tesla revealed the third generation of its charging stations. The new V3 Supercharger is capable of charging at a rate of 250kW, which is fast enough to add 75 miles of range in 5 minutes (a 1000+ mph charging rate).
What influences charging speeds?
There are multiple factors that affect the charging speed, such as:
- Current charge. An empty battery charges faster then one that’s almost full (see below).
- Vehicle charging rate. The maximum charge rate the vehicle can accept.
- Chargepoint charging rate. The maximum charge rate of the charging station.
- Temperature. Cold temperatures decrease charging speeds.
When you’re visiting a Supercharger (or another charging stations) we recommend to charge your battery to 80%. The reason is that as the battery gets more full it has to be charged more slowly.

Good to know: the charge curve of each vehicle is different. It’s based on the technical specifications of the battery and the charger.
