A 64 kWh battery takes about 6.9 hours to go from 10% to 80% on a 7.2 kW home charger, and about 60 minutes on a 50 kW fast charger.

How it is computed
Energy added = battery capacity × 70%. Time = energy added ÷ (charger power × 90% efficiency). Fast chargers slow down as the battery fills and the car caps the power it accepts, so real DC times can be longer.
FAQ
Why stop at 80%?+
Above about 80% the car tapers the charging power to protect the battery, so the last 20% can take as long as the first 70%. Most road-trip planners charge 10% to 80%.
Why is my fast charge slower than the table?+
The car limits the power it accepts, more so when the battery is cold or nearly full. A 150 kW charger only delivers 150 kW if the car can take it.
