For an electric car which relies on electrical energy from the battery to heat the cabin, the advantage of using a heat pump to warm the inside of the car compared to a conventional electric heater is obvious, it uses less energy. The energy a heat pumps saves can be used to power the car and increase range. How do heat pumps work?
In an electric car, a heat pump is used to get the cabin up to temperature using heat from the battery pack. The car can also use the heat pump to keep the battery at an optimal temperature to improve charging performance, range and battery longevity - particularly in cold weather when lithium-ion batteries in electric cars perform less well.
Cars with heat pumps also proved more efficient, averaging 3.2 miles/kWh, compared with 2.9 miles/kWh for ones without. Other benefits of a heat pump? Heat pumps are also used to keep the battery at an optimal temperature.
A large number of newer EVs come with heat pumps, but not all. Luxury brands like BMW and Tesla offer heat pumps as standard in all their electric cars, as do some more affordable brands such as Renault. However many brands don't offer them as standard, such as Audi, Skoda and Volkswagen, and you'll need to buy one as an optional extra.
