Home Charging CalculatorUse the Home Charging Calculator to find out how long and how much it costs to charge at home. The results can be tailored to your home energy costs.Most suppliers provide two power rating options, either a “standard” 3kW or “fast” 7kW. You can find out more about domestic EV charging at our Charging at Home page. Expect to pay more for the 7kW option, however it will reduce charge time significantly if the car has a faster on-board charger. For example, a Nissan LEAF 40 kWh plugged into a 3kW home charge unit will provide a full charge in 6-8 hours, whereas a 7kW unit will take 3-4 hours. More information on charging capabilities of many of the UK’s best-selling EVs can be found at Zap-Map’s EV Charging Guides section.To find more information on how to use the Home Charging Calculator, follow the link to the Home Charging Calculator Guide.
