DETAILED DESCRIPTION

[0022] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0023] In this disclosure, unless otherwise specified, "inside" and "outside" refer to the "inside" and "outside" relative to the outline of the corresponding component itself. In addition, the terms "first," "second," "third," etc. used in this disclosure are intended to distinguish one element from another and do not have sequential or importance. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same figure numbers in different drawings represent the same or similar elements. The above definitions are used only to explain and illustrate this disclosure and should not be understood as limiting this disclosure.

[0024] The battery system in an exemplary embodiment of the present disclosure will be described below with reference to the accompanying drawings.

[0025] refer to Figures 1 to 3 As shown, the present disclosure provides a battery system, including a battery stack module 1, a liquid supply module 2 and a heat dissipation module 3, wherein the liquid supply module 2 is used to store electrolyte, the liquid supply module 2 is located at the bottom of the battery stack module 1 and is detachably connected to the battery stack module 1; the heat dissipation module 3 is used to cool the electrolyte in the liquid supply module and / or the electrolyte circulating through the liquid supply module 2 and the battery stack module 1, the heat dissipation module 3 is arranged on the top of the liquid supply module 2 and adjacent to the battery stack module 1, and / or the heat dissipation module 3 is arranged in the liquid supply module 2. When the battery system is working, the electrolyte in the liquid supply module 2 will circulate between the battery stack module 1 and the liquid supply module 2 under the action of the pump body to ensure the normal operation of the battery stack module 1, and the heat dissipation module 3 can dissipate heat for the circulating electrolyte to prevent the electrolyte from overheating and affecting the working effect of the battery system. When problems occur in the battery stack module 1 or the liquid supply module 2 or maintenance is required, since the battery stack module 1 and the liquid supply module 2 are detachably connected, the staff can disassemble and replace the battery stack module 1 or the liquid supply module 2 separately according to needs, which is convenient for subsequent maintenance and repair operations. In addition, the heat dissipation module 3 is set on the top of the liquid supply module 2 and / or inside the liquid supply module 2, so that the battery stack module 1, the liquid supply module 2 and the heat dissipation module 3 can be tightly connected together, reducing the space occupied by the battery system as a whole and improving the integration of the battery system.

[0026] It should be noted that, when the heat dissipation module 3 is disposed on the top of the liquid supply module 2 , it can also be detachably connected to the liquid supply module 2 , so as to further facilitate the disassembly, assembly and replacement of each module in the stack module 1 .

[0027] In addition, the battery system of the present disclosure may be an air battery system, such as an aluminum-air battery system, a zinc-air battery system, or a lithium-air battery system, etc., and the present disclosure is not limited to this.

[0028] In some embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the stack module 1 includes a first box body 11 and a stack unit 12 . The stack unit 12 is detachably disposed in the first box body 11 . The bottom of the first box body 11 is detachably connected to the liquid supply module 2 . That is, the battery stack unit 12 is arranged in the first box body 11 and is connected to the liquid supply module 2 through the first box body 11, and can be taken out from the first box body 11 as needed. This can facilitate the staff to replace the battery stack unit 12 separately when there is a problem with the battery stack unit 12. For example, the first box body 11 can be provided with a limiting structure such as a card slot or a card block. The limiting structure can prevent the battery stack unit 12 from slipping out of the first box body 11 after the battery stack unit 12 is installed in the first box body 11; and when the battery stack unit 12 needs to be taken out, it is only necessary to take the battery stack unit 12 out of the limiting structure, thereby realizing the connection and separation between the battery stack unit 12 and the battery stack module 1; on the other hand, the first box body 11 can also provide a certain protection for the battery stack unit 12 to avoid external force directly acting on the battery stack unit 12 and damaging the battery stack unit 12.

[0029] In addition, multiple battery stack units 12 can be provided according to the requirements of the battery system, so that multiple installation spaces for placing the battery stack units 12 can be provided on the first box body 11. Each battery stack unit 12 can be placed in a corresponding installation space and the battery stack units 12 can be connected in series to change the current and voltage of the battery stack module 1; in addition, the above-mentioned limiting structure can be provided in each installation space to prevent the battery stack unit 12 from slipping out of the installation space.

[0030] Of course, in order to observe the status of the battery system in real time, a human-computer interaction interface can also be set on the first box 11 to display information such as the current and voltage of the battery system and the temperature and usage of the electrolyte in the liquid supply module 2.

[0031] In some embodiments, as Figure 1 and Figure 2As shown, the liquid supply module 2 includes a second box body 21 and a working liquid tank 22 arranged in the second box body 21. A connecting piece 23 is provided on the top of the second box body 21. The connecting piece 23 is used to be connected to the battery stack module 1 and the working liquid tank 22 respectively through a pipe group so that the electrolyte can circulate in the working liquid tank 22 and the battery stack module 1; the heat dissipation module 3 is arranged on the top of the second box body 21 and / or is arranged in the second box body 21 and is adjacent to the working liquid tank 22. The second box body 21 can provide certain support for the battery stack module 1 and / or the heat dissipation module 3 to prevent the battery stack module 1 and the heat dissipation module 3 from being directly pressed on the working liquid tank 22, thereby causing the working liquid tank 22 to be damaged due to the large pressure. In addition, the second box body 21 can also prevent external force from directly acting on the working liquid tank 22; the connecting piece 23 may include a first liquid connector 231 and a second liquid connector 232, wherein the first liquid connector 231 can be used to be connected to the liquid inlet pipe group 5 of the pipe group, and the second liquid connector 232 can be used to be connected to the liquid outlet pipe group 6 of the pipe group, thereby, the electrolyte in the working liquid tank 22 can enter the battery stack module 1 through the liquid inlet pipe group 5 and the first liquid connector 231 and flow back to the working liquid tank 22 through the liquid outlet pipe group 6 and the second liquid connector 232, thereby completing a cycle of the electrolyte.

[0032] Of course, in order to facilitate the output of electrical energy in the stack module 1 , an electrical connector may also be provided on the second box 21 to be electrically connected to the stack module 1 .

[0033] In some embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the heat dissipation module 3 may include a third box body 31 and a heat dissipation portion 32. The third box body 31 is arranged on the top surface of the second box body 21 and extends along the height direction of the second box body 21. The heat dissipation portion 32 is arranged in the third box body 31 and / or in the second box body 21 and is arranged adjacent to the working liquid tank 22. The heat dissipation portion 32 can dissipate heat from the circulating electrolyte to ensure that the electrolyte is always at a suitable working temperature and to prevent the electrolyte from affecting the working efficiency of the battery system due to excessive temperature. The third box body 31 is arranged on the second box body 21 of the liquid supply module 2 so that the heat dissipation module 3, the stack module 1 and the liquid supply module 2 are closely connected together, reducing the space occupied by the battery system, and the heat dissipation portion 32 can be arranged on the third box body 31 or in the second box body 21 as needed to dissipate heat from the electrolyte in different ways.

[0034] Specifically, if Figure 1 and Figure 2As shown, the heat dissipation portion 32 may include at least one of a plate heat exchanger 321 and a cooler 322 . The plate heat exchanger 321 may include a radiator body and a heat pipe connected to the radiator body. The radiator body is arranged adjacent to the working fluid tank 22 and is connected to the tube group. Refrigerant is arranged in the heat pipe. The heat pipe can be arranged between the second box body 21 and the third box body 31 and is arranged adjacent to the cooler 322 in the third box body 31. In this way, the electrolyte in the working fluid tank 22 can exchange heat with the refrigerant in the heat exchanger body during the process of flowing through the liquid inlet pipe group 5 and the liquid outlet pipe group 6, thereby achieving a cooling effect; the cooler 322 can dissipate heat for the heat pipe. Specifically, the cooler 322 may include a shell, heat dissipation fins connected to the shell and a fan connected to the heat dissipation fins. After the refrigerant after heat exchange passes through the cooler 322, the heat dissipation fins of the cooler 322 can be used to dissipate heat for the refrigerant in the heat pipe. The fan is used to further cool the refrigerant and the heat dissipation fins to ensure the temperature of the refrigerant in the heat pipe, thereby indirectly dissipating heat for the electrolyte in the working fluid tank 22 and improving the heat dissipation efficiency.

[0035] Of course, in some embodiments not shown in the figures, the cooler 322 may also be disposed adjacent to the working fluid tank 22 to directly dissipate heat from the working fluid tank 22 and the refrigerant in the heat dissipation pipe.

[0036] In some embodiments, as Figure 1 and Figure 2 As shown, the battery system also includes an intermediate liquid tank 4, which is arranged on the second housing 21 and adjacent to the stack module 1. The intermediate liquid tank 4 is connected to the working liquid tank 22 in an on-off manner. The intermediate liquid tank 4 also contains electrolyte. When the electrolyte in the working liquid tank 22 needs to be replaced, the electrolyte in the working liquid tank 22 can be drained and replaced with the electrolyte in the intermediate liquid tank 4. The intermediate liquid tank 4 is arranged on the second housing 21, rather than being separately arranged next to the liquid supply module 2 and / or the stack module 1, which can also reduce the space occupied by the battery system.

[0037] Among them, such as Figure 1 and Figure 2 As shown, the capacity of the intermediate liquid tank 4 can be the same as that of the working liquid tank 22. This allows the intermediate liquid tank 4 to completely replace the waste liquid in the working liquid tank 22 at one time, thereby improving the efficiency of replacing the electrolyte.

[0038] In some embodiments, as Figure 1 and Figure 2As shown, the intermediate liquid tank 4 is disposed within the third housing 31, and the cooler 322 is disposed adjacent to the intermediate liquid tank 4. Since only the cooler 322 and a portion of the heat dissipation pipes are disposed within the third housing 31, there is still ample space within the third housing 31. Therefore, the intermediate liquid tank 4 can also be disposed within the third housing 31, adjacent to the cooler 322 and the heat dissipation pipes. This saves space occupied by the entire battery system while still providing some protection for the intermediate liquid tank 4.

[0039] In the embodiments of the present disclosure, Figure 1 and Figure 2 As shown, the second box body 21 and the third box body 31 are integrally formed to form an L-shaped box structure, which can save the space occupied by the two.

[0040] In addition, if Figure 1 and Figure 2 As shown, heat dissipation holes may be provided on the stack module 1 and / or the liquid supply module 2 and / or the heat dissipation module 3 to further enhance the heat dissipation effect of the battery system and ensure the normal operation of the battery system.

[0041] In summary, the present disclosure exemplarily illustrates the use process of the battery system.

[0042] When the battery system is in use, the electrolyte will circulate between the stack unit 12 of the stack module 1 and the working liquid tank 22 of the liquid supply module 2 under the action of the pump body to ensure the normal operation of the stack module 1, and the heat dissipation module 3 can dissipate heat for the electrolyte to prevent the overheating of the electrolyte from affecting the operation of the battery system. When the battery system needs to be repaired, since the stack module 1 and the liquid supply module 2 are detachably connected, the staff can disassemble and assemble the corresponding modules according to needs to improve the efficiency of the maintenance work. In addition, the heat dissipation module 3 is arranged on the top of the liquid supply module 2 and / or inside the liquid supply module 2, so that the stack module 1, the liquid supply module 2 and the heat dissipation module 3 can be tightly connected together, reducing the space occupied by the battery system as a whole and improving the integration of the battery system.

However, the present disclosure is not limited to the specific details of the above embodiments.
