![]() Pure electric vehicles have limited battery capacity and short range, so there are strict requirements for the energy consumption and efficiency of the air conditioning system. Air conditioning systems can provide a comfortable interior environment for the driver and occupants under complex and changing driving conditions ( Sharif et al., 2016). Although electric vehicles have great potential for development, shortcomings such as short range and long charging time limit the popularity of pure electric vehicles.īoth new energy vehicles and conventional vehicles require a comfortable driving environment. Among them, pure electric vehicles, with their characteristics of no pollution, low noise, and high efficiency, have received wide attention from automobile manufacturers and consumers and have gradually become an important research direction for the transformation and upgrading of the automobile industry ( Wang et al., 2016 Li et al., 2019). Under the pressure of energy crisis and environmental pollution, new energy vehicles came into being. Therefore, the automotive air conditioning industry is facing a shift and challenge from a single indicator of comfort to comprehensive energy saving and emission reduction. With the rising awareness of environmental protection in various countries and the rapid development of technology in the new energy vehicle industry, it is the trend for vehicles to develop from traditional fuel vehicles to new energy. During this period, although the components within the automotive air conditioning system have been continuously updated, its entire system based on mechanical compression for cooling and the use of waste heat from fuel vehicles for heating has remained almost unchanged ( Ahn et al., 2016 Kalinichenko et al., 2018 Lee et al., 2022). The proposed research study can lay the foundation for further optimizing the design of heat pump air conditioners for electric vehicles.Īutomotive air conditioning technology has been developed for nearly 70 years since the 1950s, when General Motors first designed and installed the first integrated heating and cooling air conditioner in a car in the United States ( Sharif et al., 2017 Bentrcia et al., 2018 Wang et al., 2020). ![]() Finally, the results show that the machine learning algorithm is able to monitor and adaptively adjust the interior temperature to further enhance the adaptability of the system with low volatility and high accuracy. ![]() Second, a fuzzy inference system is constructed based on the machine learning model to observe the temperature of the passenger compartment using the temperature sensor inside the tram and to determine the need for the air conditioning system to be turned on in the heating/cooling mode by comparing it with the set temperature. First, the advantages and disadvantages of different heat pump models for new energy vehicles are analyzed and compared. ![]() In order to break through the existing battery technology of electric vehicles, this paper proposes to use heat pump air conditioning instead of the original PTC heating system potential.
