Step S5: the temperature sensor 410 is provided to the thermal management component.

The flow rate adjustment device 420 is a structure for adjusting the flow rate of the cooling medium supplied to the heat management member by the buffer device 200. In some embodiments, the flow regulating device 420 is a valve that regulates the flow of cooling medium to the thermal management component by regulating the opening of the valve. In other embodiments, the flow regulating device 420 is a pump body that regulates the flow of cooling medium to the thermal management component by regulating the power of the pump body. The temperature sensor 410 is a structure for detecting the temperature of the thermal management component. The temperature sensor 410 can acquire the temperature of the thermal management component to provide a basis for flow regulation of the cooling medium.

Before the heat management component is cooled by the battery disassembling apparatus 10, the temperature sensor 410 is provided to the heat management component, that is, step S5 is located before step S3. The buffer device 200 is connected to the medium inlet 810, the storage device 100 is connected to the medium outlet 820, and the temperature sensor 410 is disposed on the thermal management component.

In the step of removing the battery cells from the thermal management component, the battery disassembly method 20 further includes: the plurality of battery cells are sequentially removed in a direction in which the cooling medium flows from the medium inlet 810 to the medium outlet 820 through the heat exchange flow path.

The heat exchange flow channel is a flow channel for heat exchange medium to flow through the heat management component. The heat exchange flow channel is communicated with the medium inlet 810 and the medium outlet 820, the heat exchange medium enters the heat exchange flow channel from the medium inlet 810 and leaves the heat exchange flow channel from the medium outlet 820, and when flowing in the heat exchange flow channel, the heat exchange medium exchanges heat with the battery cell, so that the heat management of the battery cell is realized.

The cooling effect at the location of the medium outlet 820 is the worst. Therefore, the plurality of battery cells are sequentially removed along the direction in which the cooling medium flows from the medium inlet 810 to the medium outlet 820 through the heat exchange flow passage, so that the disassembly is more convenient, and the consumption of the cooling medium can be reduced.

Along the extending direction of the heat exchanging flow channel, the cooling medium has better cooling effect near the medium inlet 810 and poorer cooling effect near the medium outlet 820. Therefore, it is more convenient to sequentially detach the plurality of battery cells along the direction in which the cooling medium flows from the medium inlet 810 to the medium outlet 820 through the heat exchange flow passage, and it is advantageous to reduce the consumption of the cooling medium and the disassembly cost.

According to some embodiments of the present application, please refer to fig. 1-22.

The embodiment of the application provides a battery disassembling device 10 for disassembling a battery 800.

The caching apparatus 200 is configured to be coupled to a media inlet 810 for providing a cooling medium to the thermal management component. Wherein the storage device 100 is adapted to be connected to the medium outlet 820 for recovering the cooling medium. The battery disassembling apparatus 10 includes a storage device 100 and a buffer device 200, wherein the storage device 100 is capable of providing a cooling medium to the buffer device 200 such that the cooling medium is buffered in the buffer device 200. The caching apparatus 200 can be coupled to the media inlet 810 to provide cached cooling media to the thermal management component. The storage device 100 can be connected to the medium outlet 820 to recover the cooling medium within the thermal management component. By introducing a cooling medium into the thermal management component, the glue layer between the thermal management component and the battery cells is cooled, so that the glue layer is embrittled, and the battery cells are detached from the thermal management component. In addition, since the buffer device 200 provides the cooling medium to the thermal management component, the storage device 100 recovers the cooling medium, and the provided cooling medium and the recovered cooling medium are not easy to interfere with each other, which is beneficial to improving the recovery effect and reducing the cooling medium consumption, thereby reducing the disassembly cost. Furthermore, the storage device 100, the buffer device 200 and the thermal management component can form a circulation, and the cooling medium recovered by the storage device 100 can be conveniently supplied to the buffer device 200 without transferring the recovered cooling medium, which is beneficial to further reducing the disassembly cost.

The battery disassembling apparatus 10 includes a first tube 300 and a first valve 310, one end of the first tube 300 is connected with the storage device 100, and the other end of the first tube 300 is connected with the medium outlet 820. The first valve 310 is disposed on the first pipe 300, and the first valve 310 is used for adjusting on/off of the storage device 100 and the thermal management component. The first pipe 300 can connect the storage device 100 and the thermal management component, and the first valve 310 is disposed at the first pipe 300. When the first valve 310 is opened, the storage device 100 is communicated with the thermal management component, and the cooling medium in the thermal management component can flow to the storage device 100, so that the recovery of the cooling medium is realized, the consumption of the cooling medium is reduced, and the disassembly cost is reduced. When the first valve 310 is closed, the storage device 100 and the thermal management component are disconnected, so that the cooling medium in the storage device 100 is conveniently supplied to the buffer device 200, and the cooling medium in the storage device 100 is not easily leaked from the first pipe body 300.

The temperature sensor 410 is capable of detecting the temperature of the thermal management component, and when the temperature sensor 410 detects that the temperature of the thermal management component is higher than the threshold, the controller 400 may control the flow adjustment device 420 to increase the flow of the cooling medium supplied to the thermal management component by the buffer device 200, thereby providing more cooling medium such that the temperature of the thermal management component is reduced. When the temperature sensor 410 detects that the temperature of the thermal management component is below the threshold, the controller 400 may control the flow adjustment device 420 to reduce the flow of the cooling medium supplied to the thermal management component by the buffer device 200, thereby reducing the supplied cooling medium to reduce the consumption of the cooling medium and the disassembly cost.

The battery disassembling apparatus 10 includes a second pipe body 430, one end of the second pipe body 430 is connected to the buffer device 200, and the other end of the second pipe body 430 is connected to the medium inlet 810.

When the temperature sensor 410 detects that the temperature of the thermal management component is higher than the threshold value, the controller 400 may increase the opening of the second valve 421, thereby increasing the flow rate of the cooling medium supplied to the thermal management component by the buffer device 200 to provide more cooling medium such that the temperature of the thermal management component is reduced. When the temperature sensor 410 detects that the temperature of the thermal management component is lower than the threshold value, the controller 400 may decrease the opening of the second valve 421, thereby decreasing the flow rate of the cooling medium supplied to the thermal management component by the buffer device 200, so as to decrease the supplied cooling medium, thereby decreasing the consumption of the cooling medium, and decreasing the disassembly cost.
