What is a heat pump?

The quick version is that heat pumps are an efficient way to move heat around from where it&#;s not wanted to where it's needed. 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.

How does a heat pump work?

Heat pumps use a compressor and a series of tubes full of refrigerant. The refrigerant is a substance that absorbs heat from the environment around it, turning from a liquid into a gas. As it cools, it condenses back into a liquid, releasing heat.

With the popularity of many electric cars, more and more people are replacing their traditional cars with electric cars.

Conventional car can use the thermal energy by the engine work to provide heat to the cab when the temperature is low in winter.

And the electric car&#;s electric motor cannot produce enough thermal energy to heat the cab.

Also, in winter, the battery chemistry is not active and the battery power cannot be fully utilized because of the low temperature. electric car owners also need to heat the battery to raise its temperature in order to make full use of the battery&#;s electrical power.

According to these factors above, electric cars will need thermal management system more. And electric car heater is one of the very important parts of electric cars.
