DC Charging – Direct Current, high power fast charging stations most commonly found on a commercial basis. Some DC chargers are provided as a free charging service, others are a nominal “paid by charge” service. (Similar to petrol/ gas stations).
Chargers most commonly used are CHAdeMO charging ports.
Example 1: A 50kWh DC Charger has a maximum charging output of 50kWh
The Nissan LEAF 24kWh has a DC inverter of 22kWh. (Allowing just 22kWh of the maximum 50kWh)
Based on the vehicle having a 24kWh battery, it would take approximately 54mins to charge from completely empty to 100%. (22kWh/24kwh = 0.91hrs)
Example 2: A 50kWh DC charger has a maximum output of 50kWh.
The Tesla 100D has an DC inverter rated to 120kWh. (It can only us 50kWh input though as this is the maximum output of this particular charging unit.)
Based on the vehicle having a 100kWh battery it would take 2 hours from completely empty to 100% full charge.
(50kWh / 100kWh = 2 hours)
