[0031] One end of the water delivery pipe 1 203 and the water delivery pipe 2 204 are arranged at one side of the circulating liquid tank 202, and the other ends are extended outward from the tank body, and are used to connect to an external water pipe to deliver water to the circulating liquid tank 202, wherein the water delivery pipe 1 203 is connected to the cold water pipeline of the vehicle circulation system to deliver cold water to the device, and the water delivery pipe 2 204 is connected to the hot water pipeline of the vehicle circulation system to deliver hot water to the device. Valves are arranged on the pipelines connected to the outside of the water delivery pipe 1 203 and the water delivery pipe 2 204, which are controlled by the controller 106.

[0032] The circulating liquid tank 202 is provided with a liquid inlet 206 and a liquid return port 208. Furthermore, the liquid inlet 206 is arranged at the bottom of the tank body, and the liquid return port 208 is arranged at the top of the tank body, which is conducive to the flow of liquid. The liquid inlet 206 is connected to the inlet of the circulating pump 205, and the outlet of the circulating pump 205 is connected to one end of the circulating pipe 207, and the other end of the circulating pipe 207 is connected to the liquid return port 208 of the circulating liquid tank 202, so as to form a liquid circulation. The circulating pipe 207 is arranged beside the battery pack above the partition plate 201, and is used for the space circulation of the battery pack 4.

[0033] When the user uses the device, the circulating liquid is added into the circulating liquid tank 202 from the water pipe 1 203 or the water pipe 2 204 according to the temperature conditions. The user starts the circulating pump 205 so that the circulating liquid in the circulating liquid tank 202 can be transported into the circulating pipe 207, thereby circulating the circulating liquid in the circulating pipe 207, thereby achieving a certain temperature regulating effect on the battery pack 4.
