[0024] In order to make the skilled in the art better understand the technical solutions of the application, the application will be further described in detail below in combination with the drawings and specific embodiments.

[0025] The term "several" as used in this article refers to a number of uncertain quantities, usually two or more; and when "several" is used to indicate the quantity of certain components, it does not mean that the quantities of these components are the same.

[0026] Please refer to Figures 1-3 , Figure 1 This is a schematic diagram of a specific embodiment of the fuel cell stack provided by the present invention. Figure 2 for Figure 1 Structural diagram of the middle insulating protective cover. Figure 3 This is a schematic diagram of a specific embodiment of the fuel cell stack provided by the present invention.

[0027] like Figure 1 As shown, the present invention provides a fuel cell stack, including a body 1, with two power take-off plates 2 on the side 11 of the body 1, which serve as the positive and negative electrodes of the fuel cell stack respectively; it also includes a cable fixing device 3 on the front 12 of the body 1, and both power take-off plates 2 are connected to the cable fixing device 3 through a transfer cable 4.

[0028] The definitions of side 11 and front 12 mentioned above are based on the installation state of the fuel cell stack. Specifically, [the definitions can be found in the original text]. Figure 3 From this perspective, fuel cell stacks in existing technologies typically include multiple fuel cell stacks, and within each stack, several stacks can be arranged laterally ( Figure 3 The left and right directions are spaced apart to form a row, in the vertical direction ( Figure 3 In the vertical direction, multiple rows of fuel cell stacks can be set up in the fuel cell stack group. In this way, the lateral end face of the fuel cell stack is its side face 11, and the end face of the fuel cell stack perpendicular to the paper and facing upward is its front face 12.

[0029] The power take-up board 2 typically extends from the side 11. Since side 11 is adjacent to the sides of two adjacent battery stacks, and there is also a frame 7 between the two adjacent battery stacks for fixing them, the installation and operating space on side 11 is very limited, making it difficult to connect the power take-up board 2 to external equipment such as electrical cabinets. Furthermore, when connecting the power take-up board 2 to the electrical cabinet, one end of the power take-up board 2 is usually connected first. To facilitate connection, the head of the power take-up board 2 extending beyond the battery stack is usually quite large. After fixing the cable to the power take-up board 2, the cable can be pulled out and connected to the electrical cabinet after bending, winding, and other wiring arrangements. During this process, the cable will exert tension on the connection end with the power take-up board 2. In severe cases, this can even cause the head of the power take-up board 2 to twist and deform, affecting its use.

[0030] And the electric pile provided by the application can transfer the power taking end of the electric pile from the relatively narrow side 11 of the electric pile to the front 12 of the electric pile with a larger operation space by arranging the adapter cable 4 and the cable fixing device 3. In this way, on the one hand, the electric pile can be conveniently connected to external equipment through the cable, and on the other hand, since the power taking plate 2 and the cable fixing device 3 are fixed in advance, the size of the head of the power taking plate 2 extending out of the electric pile does not need to be too large, and the material of the power taking plate 2 can be saved.

[0031] More importantly, when connected to the electrical cabinet, the power taking plate 2 and the cable fixing device 3 are already fixed, which can greatly reduce the workload and assembly difficulty of the electric pile end, and at the same time, can also avoid the influence of dragging the cable on the head of the power taking plate 2, which is beneficial to ensure the reliable connection between the electrical cabinet and the electric pile.

[0032] Further, the cable fixing device 3 can be a cable connector, and the electric pile can be connected to external equipment through the cable by the cable connector. That is, during installation, only a simple plugging operation of the cable and the cable connector is needed to complete the installation and disassembly of the electric pile and the external equipment, which can greatly simplify the disassembly process and greatly reduce the maintenance difficulty in the later period.

[0033] At the same time, the electric pile with the above structure also has good interchangeability, which is convenient for large-scale application. When a certain electric pile in the system needs to be replaced due to failure, the cable connected to the cable connector of the electric pile can be directly unplugged, and the electric pile can be replaced as a whole, so that the replacement efficiency is greatly improved. Compared with the traditional bolt connection, the above connection method does not require tightening torque, which not only improves the installation efficiency, but also greatly improves the connection reliability of the external cable and the electric pile.

[0034] Specifically, the front 12 of the electric pile can be provided with a threaded hole, and the cable connector can be fixed to the body 1 by a connecting piece such as a screw. Of course, the cable connector and the body 1 can also be fixed by bonding, clamping or other fixing methods, and the specific installation method can be selected according to actual needs.

[0035] The adapter cable 4 and the power taking plate 2 can be connected by a terminal, which is preferably a 90-degree terminal 5, so as to realize the transfer of the power taking end of the electric pile from the side 11 to the front 12. The terminal can also be a common terminal in a straight line shape, and at this time, the adapter cable 4 can be wound to achieve the above technical effect.

[0036] Please continue to refer to Figure 1 The electric pile provided by the application can also include an insulating protective cover 6, which can be arranged at the connection between the adapter cable 4 and the power taking plate 2 to provide insulation protection for the connection, so that the connection can be protected from damage caused by external environmental factors or surrounding components to a greater extent.

[0037] The insulating protective cover 6 can be fixed to the fuel cell stack by means of screws or other connectors, or by welding, bonding or snap-fitting. In specific embodiments of the present invention, the insulating protective cover 6 is preferably fixed by snap-fitting to facilitate the installation and removal of the insulating protective cover 6.

[0038] The insulating protective cover 6 may include a cover body 61. One end face of the cover body 61 opposite to the fuel cell stack may have a snap-fit ​​portion 62, and the other end may have a slot. The snap-fit ​​portion 62 can snap into the slot, thereby achieving the connection between the insulating protective cover 6 and the fuel cell stack. Specifically, as... Figure 2 As shown, the snap-fit ​​part 62 can be provided on the cover 61, and there can be multiple snap-fit ​​parts, so as to ensure the reliability of the connection between the insulating protective cover 6 and the fuel cell stack.

[0039] The present invention can also provide an electric stack assembly, including a plurality of electric stacks, which are the electric stacks involved in the above embodiments.

[0040] Since the aforementioned fuel cell stack already possesses the technical effects described above, fuel cell stacks with this stack should also possess similar technical effects, so they will not be elaborated upon here.

[0041] like Figure 3 As shown, the battery stack group may also include a frame 7, and each battery stack can be installed on the frame 7. Several battery stacks can be arranged at intervals along the lateral direction to form a row. In the longitudinal direction, multiple rows of battery stacks can be arranged. In each battery stack in the same row, the sides 11 of two adjacent battery stacks can be arranged opposite each other, that is, the lateral end face of each battery stack is the side face 11.

[0042] The present invention can also provide a power supply system, including an electrical cabinet and the battery stacks involved in the above embodiments, wherein the battery stacks in the battery stacks can be connected to the electrical cabinet via cables through their cable connectors.

[0043] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
