EV efficiency in mi/kWhMeasuring your miles per kilowatt hour (mi/kWh) is a useful figure as it is the EV equivalent of MPG for a fuelled vehicle. Although most EV vehicles should tell you this figure on the dashboard, our mi/kWh Calculator can still come in handy to double check.

Much as an ICE car’s efficiency can be measured by working out how many miles can be covered using one gallon of fuel, an EV car’s efficiency can be measured by calculating how many miles can be travelled using one kilowatt hour of electrical energy.

You can then use this figure in the Energy Cost Calculator to obtain your travelling costs over various distances.

The table to the right shows the energy efficiency for some common models. EV’s are generally most efficient when travelling around town with stop-start traffic. Higher speeds tend to cause a loss of range due to increased wind resistance.
