Embodiment Construction

[0028] Refer below figure 1 A thermal management system 100 for a vehicle according to an embodiment of the present invention is described, and the thermal management system 100 can be applied to a hybrid system of a vehicle.

[0029] Such as figure 1 As shown, the thermal management system 100 of the vehicle according to the embodiment of the present invention includes: an engine 1 connected in series, a radiator 2, a first flow regulating valve 3, a battery 4, a second flow regulating valve 5, a motor controller 6, a first Three flow regulating valves 7 and a motor 8, and the motor 8 communicates with the engine 1 to form a cycle. That is to say, the coolant passing through the motor 8 re-flows into the engine 1, thereby forming a circulation loop. When the thermal management system 100 is working, the coolant passes through each component, and the coolant in the circulation loop can continuously improve the performance of the engine 1 and the battery. 4. The operating tem...

Abstract

The invention discloses a thermal management system of a vehicle, a control method thereof, and the vehicle. The thermal management system includes: an engine connected in series, a radiator, a first flow regulating valve, a battery, a second flow regulating valve, a motor controller, and a second flow regulating valve. Three flow regulating valves and a motor, the motor is connected with the engine to form a cycle, wherein, the first flow regulating valve is also connected with the first pipeline between the second flow regulating valve, the second flow regulating valve and the third flow regulating valve A second pipeline is connected between the valves, and a third pipeline is connected between the third flow regulating valve and the engine. As a result, the flow of coolant flowing to the battery, motor controller and motor can be effectively controlled, so that fine control of the flow of coolant can be achieved, and the battery, motor controller and motor can be maintained within their respective operating temperature ranges, thereby maintaining The best working condition can prolong the service life of each component.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a thermal management system of a vehicle, a control method thereof and a vehicle. Background technique [0002] With the rapid development of the automobile industry, higher requirements are put forward for the energy saving and emission reduction of automobiles. The hybrid system has become the focus of major industry research and has become one of the mainstream branches of new energy power system development. There is a lot of room for development. [0003] At present, the cooling system of hybrid power system is generally controlled by modules separately, and the difference of products puts forward higher requirements for system integration. [0004] The charging and discharging efficiency of the battery is greatly affected by the temperature. When the temperature is too low, it is difficult to start the battery purely by electric heating. Heating the battery by electric he...
