Description
Technical Field
The application belongs to the technical field of new forms of energy, especially, relate to a thermal management system device and electric automobile.
Background
At present, the power electronic technology is widely applied to the field of new energy automobiles. The technical development of electric vehicles is also becoming mature. Compared with the traditional fuel oil automobile, the electric automobile can not exhaust tail gas and cause air pollution. Along with electric power fills electric pile's popularization, the use of electric motor car is also more convenient. And compared with the traditional energy, the use cost of the electric vehicle is relatively low. The overall dynamic performance and driving comfort of the electric vehicle also improve the user experience.
With the popularization of electric vehicles, users have made higher demands on the use experience of electric vehicles. In the passenger compartment, under the influence of the external environment, a user has the use requirements of heating and refrigeration, and the automobile air conditioner and the heating need to respond better. Particularly, in the weather of ice and snow and high humidity, the electric automobile needs to remove frost and fog on the glass in time so as to ensure the driving visual field of a user; in the aspect of battery use, the problems of user safety and automobile energy consumption need to be solved under the influence of high-temperature and low-temperature environments. The battery can not be in a low-temperature state for a long time to cause no electric loss, and can not be in a high-temperature state for a long time to avoid the influence on personal safety caused by natural accidents; in the aspect of using of motors and power transformation equipment, the electric automobile needs to be cooled in time under the influence of high temperature of high-power electric parts, so that electric elements are not damaged due to overload. However, the electric automobile industry is affected by traditional automobiles, and fast iterative development and heat management systems are not provided with integrated application of the system and precise control of the system. The heating of the passenger compartment and the heat preservation of the battery are not good enough, so that the user has the worry of fast electricity consumption or short endurance mileage. What is more, the battery is overheated to cause a serious safety accident.
Most of electric automobiles at the present stage use scattered electric components to form complex pipeline wiring, the integration level is low, the system is heavy, and the occupied space is large. The management of the passenger compartment, the battery, and the power transformation equipment is not perfect in the overall temperature management mode. The large number of pipe systems and discrete components increases the manufacturing costs of the vehicle. Some electric vehicles can heat and cool batteries or motor drives, but require a plurality of additional systems to heat and cool passenger compartments or batteries, which is not conducive to improving the driving experience of users and also increases the manufacturing cost of electric vehicles. Still some electric vehicles need to heat or cool multiple internal components of the device simultaneously, and individual heating or cooling of each component cannot be achieved, but in some cases, a user may only need to apply a part of the heating or cooling, the excess energy may be consumed, and the application of the heating and cooling may also be in conflict. This kind of condition has reduced electric automobile's electric quantity or continuation of the journey mileage, gives the not good experience of user simultaneously.
