High Speed DC Charging (10% - 80%)

Rapid charging enables longer journeys by adding as much range as possible in the shortest amount of time. Charging power will decrease significantly after 80% state-of-charge has been reached. A typical rapid charge therefore rarely exceeds 80% SoC. The rapid charge rate of an EV depends on the charger used and the maximum charging power the EV can handle. The table below shows all details for rapid charging based on using a high speed DC charger that meets or exceeds the car’s max high speed charger speed. Figures in the table are calculated using:

• Assumes the high speed DC charger meets or exceeds the car’s max high speed charger speed.
• Average power accepted by the vehicle over a session from 10% to 80%.
• Full Charge Time: time needed to charge from 10% to 80%.
• Full Charge Cost: Based on £0.75/kWh charging from 10% to 80%

Home charging costs & assumptions

• Off peak: £0.08/kWh (default)
• Peak: £0.30/kWh
• Household 3 Pin socket max charging rate is 10A/2.3kW as this is the max permissible under UK wiring regulations.  
• Full Charge Cost (off-peak)’ & ‘Cost per mile (off-peak)’ - Full Charge Cost (off-peak)’ & ‘Cost per mile (off-peak)
• Home Wall Charger 'Full Charge Time' and 'Range per Hour' are based on whichever is lower, the wall box's output (7.4kW) or the car's onboard charger rating, since charging speed is always limited by the smaller of the two.
