How much to charge an electric car?
Electric car charging at home
The cost of charging your electric car at home depends on the model of your vehicle, the wattage of your home charger and the cost of your electricity rate.
You may be able to switch to an EV electricity tariff, which can be beneficial for those who charge at home.
Most home EV chargers typically offer either 7kW or 3kW of power. The more power in the charger, the quicker your electric vehicle will be ready to hit the road, but often it’ll cost more to buy.
Some chargers offer multiple power settings. This gives you more flexibility to either short-term quick charge or gently power up your car overnight to give you peace of mind that it will be fully recharged the next morning. You can use a regular power outlet for this but for the best results, you’ll want to have a home charger installed.
