Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0017] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0018] Figure 1 This is a schematic diagram of the structure of a single battery compartment provided in one embodiment of the present invention. Figure 2 This is a schematic diagram of the structure of a battery cell 12 provided in one embodiment of the present invention. Figure 3 yes Figure 2 A partial breakdown diagram. Figure 4 This is a schematic diagram of the structure of the liquid cooling plate 122 provided in one embodiment of the present invention. Figure 5 This is a schematic diagram of the back-end structure of a battery module provided in one embodiment of the present invention.

[0019] like Figures 1 to 5 As shown, the prefabricated energy storage battery compartment may include, but is not limited to: The single battery compartment includes multiple layers of battery units 12 arranged in a specific configuration. The exact number of layers of battery units 12 is not limited and can be selected and configured according to the actual application scenario. Battery cell 12 includes a liquid cooling plate 122, a conductive element 123, and at least one battery module 121; wherein, The battery module 121 has a guide pin 1211 at the rear end that serves as a limiting connection. The shape, capacity, and performance of the battery module 121 can be set according to the actual scenario. This part is not an inventive point of this embodiment, so it will not be described in detail here. The conductive element 123 includes an integrally connected conductive part and an insulating part 1231, the conductive part being used to make a conductive connection with the battery module 121; The liquid cooling plate 122 has a first mounting hole 1221 on its side for detachable connection with the guide pin 1211, and a second mounting hole 1222 on its top for fixing the insulating part 1231.

[0020] As can be seen, this embodiment is configured with a single battery compartment including multiple layers of battery cells 12, which has good compatibility and small size. For each battery cell 12, it is detachably connected to the guide pin 1211 at the rear end of the battery module 121 through the first mounting hole 1221 on the side of the liquid cooling plate 122. This ensures the stable installation of the battery module 121 and allows for easy disassembly of the battery module 121 without the use of large tools, making it easy to insert or remove, facilitating maintenance and repair, and significantly reducing maintenance costs. Furthermore, it is also equipped with a battery pack. The conductive element 123, which includes an integrally connected conductive part and an insulating part 1231, is fixed by the insulating part 1231 of the conductive element 123 through the second mounting hole 1222 on the top of the liquid cooling plate 122, thereby fixing the entire conductive element 123. This allows the conductive part to be stably conductively connected to the battery module 121, ensuring that the battery module 121 has good performance. In addition, the above-described mounting method can effectively embed the liquid cooling plate 122 into the battery cell 12, thereby providing a stable and reliable heat dissipation effect for the entire battery cell 12.

[0021] In one embodiment, such as Figure 2 , Figure 3 As shown, two battery modules 121 can be configured. The liquid cooling plate 122 has first mounting holes 1221 on both sides to match one of the corresponding battery modules 121. That is, in this case, the guide pins 1211 of the two battery modules 121 can be matched and connected to the first mounting holes 1221 on one side of the liquid cooling plate 122, thereby ensuring that the two battery modules 121 can be fixed at the same time. Similarly, if only one battery module 121 is configured, it only needs to be connected to the first mounting hole 1221 on one side of the liquid cooling plate 122. The following embodiments are mainly based on the case of two battery modules 121, but should not be construed as a limitation.

[0022] In one embodiment, the conductive element 123 may be, but is not limited to, at least two, and the number of second mounting holes 1222 is not less than the number of conductive elements 123 to achieve matching and fixing. The specific number can be set according to the actual application scenario and is not limited here. For example, refer to Figure 3 , Figure 6 The conductive element 123 is set to two, and the number of the second mounting holes 1222 is set to 4 groups, totaling 8.

[0023] In one embodiment, such as Figure 6 As shown, the conductive part may include, but is not limited to, a quick-connect terminal 1232 and a bent conductor 1233. The quick-connect terminal 1232 has a groove on its side for inserting and fixing one end of the conductor 1233. Since the quick-connect terminal 1232 is integrally connected to the insulating part 1231, fixing the insulating part 1231 through the second mounting hole 1222 achieves the fixing of the quick-connect terminal 1232. Therefore, the quick-connect terminal 1232 can further fix one end of the conductor 1233 through the groove. Furthermore, referring to… Figure 2 With the guide pin 1211 matched and connected to the first mounting hole 1221, the other end of the conductor 1233 abuts against the battery module 121 to achieve conductive connection of the battery module 121. Specifically, Figure 2 In the case shown, since both battery modules 121 are in contact with the conductor 1233, a conductive connection between the front and rear battery modules 121 can be achieved.

[0024] In one embodiment, such as Figure 3 , Figure 4 As shown, the battery unit 12 may also include, but is not limited to, a base plate 124. The base plate 124 is provided with multiple parallel and spaced wire harness fixing plates 126. The spacing and number of the wire harness fixing plates 126 can be set independently. Each wire harness fixing plate 126 can be used to fix and bind the corresponding wire harness. The bottom of the liquid cooling plate 122 is engaged with each wire harness fixing plate 126 to form a push-in groove 125. The push-in groove 125 matches the bottom of the battery module 121. Specifically, during installation, since the liquid cooling plate 122 is an independent unit, it can be placed in first. The bottom of the liquid cooling plate 122 can preferably be coated with thermally conductive adhesive. Then, the assembled battery module 121 is inserted into the base plate 124 through the push-in groove 125. After being inserted into the base plate 124, the battery module 121 is fixed by engaging its own guide pin 1211 with the first mounting hole 1221 on the liquid cooling plate 122.

[0025] In one embodiment, reference is made to Figure 1 , Figure 7Both sides of the single battery compartment may be provided with fixing beams 14, but not limited to. The front end of the battery module 121 is provided with a horizontal fixing plate 1212 for fixing the installation position of the battery module 121. The two ends of the horizontal fixing plate 1212 are detachably connected to their respective fixing beams 14. The advantage of this installation is that it can be quickly disassembled during maintenance. It can be seen that for battery units 12 of different layers, the single battery compartment can be provided with corresponding fixing beams 14 for the corresponding number of layers, so as to fix the battery units 12 of each layer well.

[0026] In one embodiment, such as Figure 1 As shown, the top of the single battery compartment may be equipped with a fire-fighting device 11, which can enable the detection and spraying of the single battery compartment and ensure the independent safety of the single battery compartment. A high-voltage box 13 is installed at the bottom to ensure cluster-level safety. The multi-layered battery units 12 are installed between the fire-fighting device 11 and the high-voltage box 13.

[0027] In one embodiment, such as Figure 8 As shown, the prefabricated energy storage battery compartment may also include, but is not limited to, the energy storage container 2. The energy storage container 2 is equipped with multiple independent single battery compartments, and the specific number is not limited and can be set according to actual needs. Each single battery compartment is equipped with a ventilation system and a pressure relief valve. The ventilation system can ensure stable air intake and exhaust of the single battery compartment, and the pressure relief valve can ensure stable pressure relief of the internal gas of the single battery compartment.

[0028] In one embodiment, such as Figure 8 As shown, the side of the energy storage container 2 may be equipped with a liquid cooling unit 3 and an electrical compartment 4 to ensure the stable operation of the liquid cooling plate 122, fire-fighting device 11, high-pressure box 13, ventilation system and pressure relief valve.

[0029] It should be noted that the specific shape of the energy storage container 2 is not limited and can be configured according to the actual needs of the scenario, for example... Figure 8 The energy storage container 2 in the middle adopts a cuboid structure.

[0030] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
