Problems solved by technology

Some electric vehicles can heat and cool the battery or motor drive, but multiple additional systems are required to heat and cool the passenger compartment or the battery, which is not conducive to improving the driving experience of users and increases the manufacturing cost of electric vehicles
There are also some electric vehicles that need to heat or cool multiple internal equipment components at the same time, and it is impossible to individually heat or cool each component. However, in some cases, users may only need to apply part of the heating or cooling, and the excess energy will be lost. Applications of heating and cooling can also conflict
This situation reduces the power or cruising range of electric vehicles, and at the same time gives users a bad experience

Abstract

The invention discloses an automobile thermal management system, a management method and an electric automobile. The system comprises an electronic compressor, a first refrigerant electromagnetic valve, a second refrigerant electromagnetic valve, a P.T temperature and pressure sensor, a water-cooling condenser, a liquid storage tank, an air-cooling condenser, a low-temperature radiator, a battery cooler, an air conditioner box, a first electronic water pump, a second electronic water pump, a third electronic water pump, a first four-way reversing valve, a second four-way reversing valve, a third four-way reversing valve, a first three-way switching valve and a second three-way switching valve. An expansion kettle, a PTC heater and a T temperature sensor. The installation position of each component of the system is more compact, and short pipeline wiring can be realized among the components, so that the occupied space of the thermal management system is reduced, the pressure and temperature loss of liquid can be reduced, the refrigeration efficiency or heating efficiency of the thermal management system is improved, and flexible control on devices with different temperature requirements is realized.

Description

technical field [0001] The invention belongs to the technical field of new energy, and in particular relates to a thermal management system, a management method and an electric vehicle. Background technique [0002] In recent years, automobile products have gained a high share in the vast number of consumer groups. With the continuous development of automotive products, electric vehicles have been widely used, and the development of related electric vehicle technologies has become increasingly mature. Compared with traditional fuel vehicles, electric vehicles are more environmentally friendly, will not directly pollute the atmosphere, and the cost of use is relatively low. With the popularity of charging facilities, the use of electric vehicles has become more and more convenient. Electric vehicles not only have strong power performance, but also have less noise when running. And in some large and medium-sized cities, there are strict regulations on the use of vehicles. C...
