In an actual application scenario, when the new energy electric vehicle runs, the temperatures of a motor and a battery in the vehicle increase along with the running time of the vehicle, and when the temperatures of the motor and/or the battery are too high, the working state of the vehicle is affected, and at this time, the motor and the battery need to be cooled through the thermal management module 1 and the heat dissipation cooling system in the vehicle.

In the embodiment of the application, when the temperature of the motor temperature simulation module 2 is set to be higher, the motor temperature simulation module 2 may increase the temperature of the liquid medium in the first pipeline and the second pipeline connected to the motor temperature simulation module 2, and at this time, the first switch and the third switch in the thermal management module 1 are turned on, so that the first circulation path and the third circulation path are connected to form a circulation loop. The heat management module 1 further comprises a water pump, and the liquid medium with the higher temperature in the first circulation passage is pumped by the water pump.

Specifically, when the set temperature of the motor temperature simulation module 2 and the set temperature of the battery temperature simulation module 3 are both high, the first switch, the second switch and the third switch can be simultaneously turned on, so that the heat dissipation simulation module 4 simultaneously cools the motor temperature simulation module 2 and the battery temperature simulation module 3; the temperature of the motor temperature simulation module 2 or the temperature of the battery temperature simulation module 3 can be respectively set, and the first switch and the third switch, or the second switch and the third switch are respectively turned on, so that the heat dissipation simulation module 4 respectively cools the motor temperature simulation module 2 or the battery temperature simulation module 3.

In a practical application scenario, when the new energy electric vehicle is located outdoors with a low temperature, the temperatures of the motor and the battery in the vehicle may be low, and at this time, the temperature of the motor and the battery needs to be raised through the thermal management module 1 and the heating system in the vehicle.

In one possible embodiment, as shown in fig. 1, the tube is a transparent tube for observing the state of the liquid medium.

In an actual application scenario, when there is no liquid medium in the pipeline or the liquid medium in the pipeline is insufficient, the liquid medium needs to be filled into the pipeline through a water pump in the thermal management module 1. During filling, if the air in the pipeline is not completely exhausted, that is, if there are still air bubbles in the pipeline, the air bubbles in the pipeline need to be completely exhausted when filling the liquid medium because the existing air bubbles form an air flow along with the flow of the liquid medium and the air flow can impact each module. In the embodiment of the application, since the liquid medium is filled through the thermal management module 1, in the application, when the liquid medium is filled, whether bubbles in the transparent pipeline are completely discharged is observed, so that the working state of the thermal management module 1 is judged. If the bubbles in the transparent pipeline are completely discharged, the thermal management module 1 works normally; if the bubbles in the transparent pipeline are not completely discharged, it indicates that the thermal management module 1 is not working normally, and the structure of the thermal management module 1 needs to be modified and adjusted.

In a specific embodiment, when the signal sensor is a temperature sensor arranged on the first pipeline, the temperature sensor sends acquired temperature information of the liquid medium in the first pipeline to the server in real time, and the server determines the working state of the thermal management module 1 according to the received temperature information of the liquid medium at different times. Specifically, at a first time, the server receives first temperature information of the liquid medium in the first pipeline, which is acquired by the temperature sensor, and at the time, the first temperature information is greater than a first temperature threshold, and between the first time and a second time, the liquid medium in the first circulation path is cooled by using the heat dissipation simulation module 4, and at the second time, the server receives second temperature information of the liquid medium in the first pipeline, which is acquired by the temperature sensor, wherein the first time is before the second time, and at the time, if the second temperature information is lower than the first temperature information and the second temperature information is less than the second temperature threshold, it is indicated that the thermal management module 1 is working normally and meets the use standard; if the second temperature information is not less than the second temperature threshold, it indicates that the thermal management module 1 is not working normally, and the thermal management module 1 needs to be adjusted and modified.

In a possible embodiment, the detection system further comprises: the server is also used for generating a starting instruction according to the received information of the liquid medium and sending the starting instruction to the thermal management module 1; the thermal management module 1 is configured to receive a start instruction, and control the first switch, the second switch, the third switch, the fourth switch, and the fifth switch to be turned on and off according to the start instruction.

In a specific embodiment, when the information of the liquid medium received by the server is temperature information in the first pipeline and/or the second pipeline, and if the server determines that the temperature in the first pipeline and/or the second pipeline is greater than the first temperature threshold, the server generates a start instruction for opening the first switch and the third switch, and sends the start instruction to the thermal management module 1. After receiving the starting instruction, the thermal management module 1 opens the first switch and the third switch to communicate the first circulation path with the third circulation path, and cools the liquid medium in the first pipeline and/or the second pipeline through the heat dissipation simulation module 4. In the application, whether the thermal management module 1 normally works is judged by detecting whether a first switch, a second switch, a third switch, a fourth switch and a fifth switch in the thermal management module 1 can be switched according to a specified condition (namely whether the switches can be switched according to a starting instruction), and if the switches can be switched normally according to the starting instruction, the thermal management module 1 works normally; if the switch can not be switched normally according to the starting instruction, the thermal management module 1 is indicated to be abnormal in operation.
