With the rapid development of the new energy vehicle thermal management industry, the overall competition pattern has formed two camps. One is a company that focuses on comprehensive thermal management solutions, and the other is a mainstream thermal management component company represented by specific thermal management products. And with the upgrading of electrification, new parts and components in the field of thermal management have ushered in an incremental market. Driven by the new battery cooling, heat pump system and other electrification upgrades of new energy vehicles, some types of parts used in thermal management solutions will follow suit. change. This paper mainly reviews and analyzes key technical components such as battery thermal management, vehicle air conditioning system, electric drive and electronic components through the analysis of the competition pattern in the field of new energy thermal management and the technical development of core components, and analyzes the new energy The technology development trend of the automotive thermal management industry has been comprehensively predicted.
At present, the thermal management scheme of traditional vehicles is relatively mature. Traditional internal combustion engine vehicles can use the waste heat of the engine for heating, but the energy required for the air conditioning system of pure electric vehicles comes from the power battery. The research of Ouyang Dong et al. also pointed out the energy efficiency of the air conditioning system The level directly affects the vehicle economy and driving range of electric vehicles. The battery thermal management system of new energy vehicles has more heating requirements than the engine thermal management system. The new energy air conditioning system uses electric compressors instead of ordinary compressors for cooling, and electric heaters such as PTC heaters or heat pumps instead of engine waste heat heating, Farrington pointed out After electric vehicles run air-conditioning heating and cooling devices, their maximum mileage drops by about 40%, which puts forward higher requirements for corresponding technologies, and the demand for technology upgrades accelerates.
With the upgrading of automobile electrification, new components in the field of thermal management are ushering in an incremental market. Driven by the new battery cooling, heat pump system and other electrification upgrades of new energy vehicles, some types of components used in thermal management solutions have also emerged. Variety. With the increase in the penetration rate of new energy vehicles and the upgrade of product performance, the future market space and value of the thermal management system industry will be huge.
In the thermal management scheme, the main application components are divided into valves, heat exchangers, electric water pumps, compressors, sensors, pipelines and other components that are used more. With the acceleration of vehicle electrification, some new components will develop accordingly. Compared with traditional fuel vehicles, the thermal management system of new energy vehicles has added electric compressors, electronic expansion valves, battery coolers, and PTC heater components(PTC air heater/PTC coolant heater), and the system integration and complexity are higher.
