Heat pumps in EVs are making a big difference in cold-weather driving

Many EV manufacturers have greatly depended on the resistance heaters that consume a large amount of energy to keep the cabin and battery warm in winter. However, heat pumps, which can reduce the loss of battery cruising range due to the cold, are becoming popular in EVs, which may help US EV owners who are dealing with low temperature in the United States this week.

EV research site The recurrence has been reported Heat pumps can improve the driving distance under freezing by about 8-10%. The site tested this by comparing the row range of the 2020 model 3 and the model S vehicle with no heat pump and the daring range of the 2021 vehicle, which is installed.

According to the Recurrent data, Tesla Model X and Audi E-Tron have lost only about 11 to 13 % compared to the traveling distance of 32 degrees of Hana at an ideal temperature of around 70 degrees. It is indicated that there is no. Washington Post MemoIt is the best category as an EV equipped with a heat pump. Washington Post The heat pump is not very effective at 15 degrees or less.

The heat pump works by efficiently transmitting the heat generated from the car to the cabin and other components. Similarly, gasoline cars have been using heater core for a long time to transmit unnecessary heat energy from internal combustion engines to the room.

The heat pump will be introduced as early as 2021 in popular EVs such as Tesla, and will be installed in other top models such as Ford Mustang Mach E in the 2025 model. It is already installed on many EVs that are currently running on public roads, including Paul Star 2, Honda Prologue, Chevrolet Equinox EV, Kia Motor EV6, Libians, and in 2013. Completely list Number of EVs equipped with heat pump.

An old EV equipped with a small battery without a heat pump appears more noticeable in the low temperature range. For example, my older sister on the 2017 Ford Focus Electric can run only about 80 miles in the extreme cold when the resistor heater is turned off, and only about 50 miles can be run. It may be a difference between whether you can go back and forth without stopping during your commuting, or if you need to find a DC quick charging station on your way home (if you can use it well).

Here are some tips on the handling of EVs in winter, which helps overcome the frozen situation on the road. Tips include adjusting the vehicle in advance with the power on before departure, or because the snow does not melt and does not fall off like a gasoline vehicle, so it is more frequent.
