Compared to filling up with petrol, running an EV is less expensive. However, for regular cars, the running expenses will depend on the vehicle size and driving habits. As a general estimate, the electricity costs for an EV are approximately one-third to one-quarter of the petrol costs for a comparable car. This cost difference may fluctuate with changes in petrol prices and assumes charging at home on a standard residential tariff.

How much electricity does it take to fully charge an electric car?

The amount of energy required to charge an EV from 0% to 100% depends on the battery capacity of the vehicle. For instance, a Tesla Model 3 has a 50 kilowatt-hour (kWh) battery, while most EV models need between 35-60kWh for a complete charge. Based on an electricity rate of $0.25/kWh, a full charge would cost around $12.50. To determine the cost of fully charging your EV, you can multiply your electricity rate by the size of your vehicle's battery.
