Research and Development Status of Heat Pump System for Electric Vehicle

Comparing to fuel vehicle, electric vehicle does not apply the heat of the engine as one of the heat resources. Therefore, many heating ideas are proposed to use on Electric vehicle.This paper analyzes the attributes of various heating methods. Heat pump system is the most popular trend of the electric vehicle business, due to the high efficiency. It suggests different heat pump systems, illustrates the trend of future market, and compares the performance of electric vehicle heat pump system using different cryogen.
