How much energy do electric cars use?

Their low energy loss makes means that they are not very energy intensive. While petrol or diesel engines convert a maximum of 35 % of this energy into driving force, an electric car reaches 90 % and more. Nevertheless, it is difficult to determine how much it costs to “fill up with electricity”, i.e. to recharge a battery, because:. read more

Most electric vehicles cover between 80 and 100 kilometres with 10 kWh. Their low energy loss makes means that they are not very energy intensive. While petrol or diesel engines convert a maximum of 35 % of this energy into driving force, an electric car reaches 90 % and more. read more

To get total energy for an electric car, take the total miles driven and divide by the average miles per kWh. That leaves the number of kWh used. Most electric cars have a readout that provides both numbers. read more

About 72%–94% of the energy used to power an electric car is used to move it down the road, depending on the drive cycle. Electric cars are more efficient than comparable conventional vehicles, especially in stop-and-go driving, due to the use of regenerative braking and start/stop technologies—see All-Electric Vehicles for details. read more
