Embodiment 1

[0048] like image 3 As shown, a cooling system provided in this embodiment includes an air intake cooling circuit 100, a battery temperature control circuit 200, and a control valve 300; the air intake cooling circuit 100 communicates with the battery temperature control circuit 200, and the control valve 300 is connected to Between the two; the control valve 300 can control the air intake cooling circuit 100 and the battery temperature control circuit 200 to operate independently; or, the control valve 300 can control the intake air cooling circuit 100 and the battery temperature control circuit 200 to form a circuit together.

[0049] The beneficial effect of this embodiment:

[0050] In the cooling system provided in this embodiment, the switching between the two circuits is realized through the control valve 300, so that the air intake cooling circuit 100 and the battery temperature control circuit 200 can operate independently, or the air intake cooling circuit 100 and t...

Embodiment 2

[0058] On the basis of embodiment one, refer to Figure 4 As shown in -5, a cooling system adjustment method provided by this embodiment includes the following steps:

[0059] S001: If Figure 4 As shown, in the heating and heat preservation stage, when the temperature T of the temperature sensor 231<10°C, under the control of the ECU control device 600, the second port 320 of the control valve 300 communicates with the third port 330, and the first water pump 110, heat dissipation The cooler 130, the second water pump 210 and the heater 240 are in the working state, and the cooler 220 and the air conditioner 250 are in the non-working state, so that the air intake cooling circuit 100 and the battery temperature control circuit 200 respectively form separate cooling systems;

[0060] S002: If Figure 5 As shown, in the passive cooling stage, when the temperature of the battery temperature sensor 231 is 10°C≤T<30°C, under the control of the ECU control device 600, the first p...

Abstract

The invention provides a cooling system and a cooling system adjusting method, which are applied to the technical field of hybrid electric vehicles carrying supercharged engines. The cooling system comprises an air inlet cooling loop, a battery temperature control loop and a control valve; the air inlet cooling loop communicates with the battery temperature control loop; the control valve is connected between the air inlet cooling loop and the battery temperature control loop; the control valve can control the air inlet cooling loop and the battery temperature control loop to run independently; or the control valve can control the air inlet cooling loop and the battery temperature control loop to jointly form a loop. According to the cooling system and the cooling system adjusting method provided by the invention, the air inlet cooling loop and the battery temperature control loop are integrated, so that the arrangement can be carried out favorably, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle cooling, in particular to a hybrid vehicle equipped with a supercharged engine, and in particular to a cooling system and a method for adjusting the cooling system. Background technique [0002] At present, with the continuous tightening of national fuel consumption and emission regulations, more and more OEMs are devoting themselves to the development of hybrid models. One of the challenges for hybrid models and pure electric models is how to further reduce fuel consumption. On the basis of this, the cost of the whole vehicle can be reduced. [0003] like figure 1 and figure 2 As shown, for a hybrid vehicle equipped with a supercharged engine, its cooling modules are responsible and diverse, including the motor cooling system, battery cooling system 1, engine cooling system and air intake cooling system 2, the above cooling systems will occupy More space, so it is a big challenge for the arra...
