Home charging will be cheaper than using public charging companies as you will be paying a commercial price for your energy – even if the charging capability is quicker. Rapid AC chargers at 43 kW using the Type 2 lead can charge a car to 80% in around 20-40 minutes. Costs vary according to location but a What Car? study found some charging stations cost more per mile than petrol or diesel, so it is worth only using public charging stations when absolutely necessary and only charging to 80% as the last 20% takes longer and so is the least cost-effective part of the charge.
