The Tesla Model S Long Range has a maximum charging speed of 250kW and takes 27 minutes to charge from 10% to 80% at this speed. If the car was capable, and it was plugged into the new V4 Supercharger, that time could be reduced to just under 11 minutes.
Of course, it’s no longer just Teslas that can use the Supercharger network these days, so faster charging here could benefit all EV drivers. The Kia EV6 and Hyundai Ioniq 5 offer two of the highest-rated charging speeds on the market when plugged into a 350kW charger. Right now it would take these cars around 18 minutes to charge from 10% to 80%, but if they could allow 615kW and were plugged into a 615kW charger, that time would be just over 10 minutes.
