Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a top-mounted, leak-proof, stacked battery. Background Technology

[0002] Stacked batteries refer to a type of battery composed of multiple battery modules stacked together. Specifically, a casing is set on the battery module, and interfaces and plugs are set on the casing to form battery blocks. The battery blocks are stacked on top of each other, and the plugs and interfaces are connected to connect different battery blocks. As needed, multiple battery blocks can be stacked and connected to form a stacked battery. Home energy storage stacked lithium batteries are a type of stacked battery. They are modular lithium battery systems designed specifically for home energy storage. Their core feature is that multiple standardized battery modules are physically stacked and electrically connected in parallel to achieve flexible capacity expansion. Stacked batteries usually consist of battery modules and a casing covering the battery modules. The casing also has stacking connectors, which are connected to the battery modules via wires. Its installation flexibility and economy are particularly suitable for photovoltaic homes, regions with diverse climates, and areas with unstable power.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: the existing stacked battery boxes are divided into two types. The protection level of the ordinary box is IP20, which can only be used in indoor environments or placed in sealed outdoor cabinets. The box for outdoor stacked batteries is made of all-aluminum alloy casting, which fully encloses all the stacked battery blocks. Although it has better waterproof performance, the casting process is complex and the cost is very high, which is not conducive to the large-scale promotion of the product. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a top-mounted, leak-proof, stacked battery that is simple to manufacture and has good sealing properties.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a top-mounted, leak-proof, stacked battery, comprising a battery body composed of several stacked battery blocks and a control block stacked on top of the battery body and electrically connected to the battery body. The battery block includes an outer shell with an opening on its top surface and a battery module fixedly installed inside the outer shell. A lifting frame with multiple through holes is fixedly provided on the top surface of the outer shell. A top cover assembly is detachably connected to the lifting frame. A plug electrically connected to the battery module is fixedly provided through the top cover assembly. An upwardly extending fastening groove is integrally formed on the bottom surface of the outer shell. An interface electrically connected to the battery module is also fixedly provided through the bottom surface of the outer shell. The size of the fastening groove is the same as the size of the top cover assembly.

[0006] A further improvement is that the bottom surface of the battery body is provided with a tray.

[0007] A further improvement is that the bottom surface of the tray is provided with a support.

[0008] A further improvement is that the outer casing has an upward-lifting groove on its side wall.

[0009] A further improvement is that the top surface of the outer shell is formed with a boss, and the boss has an inclination of 5°-10°.

[0010] A further improvement is that the top cover assembly includes a top cover plate with the same size as the snap-fit ​​groove and a connecting frame with a threaded hole that can mate with the through hole of the lifting frame, which is fixedly disposed on the bottom surface of the top cover plate. The connecting frame can be detachably connected to the lifting frame.

[0011] A further improvement is that a waterproof adhesive strip is provided between the inner wall of the connecting frame and the outer wall of the lifting frame.

[0012] A further improvement is that an adhesive layer is formed between the inner wall of the connecting frame and the outer wall of the lifting frame through threaded holes.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: During production, only the outer shell needs to be formed, an interface installed on the outer shell, and a lifting frame fixedly installed on the outer shell. Then, the battery module is assembled into the outer shell, and the battery module is electrically connected to the interface on the outer shell via wires. Subsequently, the battery module is electrically connected to the plug on the top cover assembly via wires. After connection, the top cover plate of the top cover assembly is placed over the opening of the outer shell, and the connecting frame and lifting frame are fitted together. Finally, the waterproof bolts are tightened to complete the installation of the battery block. When multiple battery blocks are stacked, the locking groove under the outer casing works in conjunction with the lifting frame and the top cover assembly to raise the position of the interface and plug. Therefore, when used outdoors, if rainwater splashes on the battery body, it is difficult for rainwater to enter between the battery blocks that are in contact with each other. Even if a very small amount of rainwater enters the gap between the battery blocks, it cannot contact the lifting frame, the top cover, and the locking groove to lift the plug and interface, thus greatly improving the waterproof performance. Moreover, there is no need to equip an additional fully enclosed cast outer casing, resulting in lower manufacturing costs. Attached Figure Description

Detailed Implementation

[0016] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0017] See Figure 1-4As shown, the technical solution adopted in this specific embodiment is: a top-mounted, leak-proof stacked battery, comprising a battery body composed of several stacked battery blocks 1 and a control block 2 stacked on top of the battery body and electrically connected to the battery body. The battery block 1 includes an outer shell 11 with an opening on the top surface and a battery module 15 fixedly installed inside the outer shell 11. A lifting frame 113 with multiple through holes is fixedly provided on the top surface of the outer shell 11. A top cover assembly 12 is detachably connected to the lifting frame 113. A plug 13 electrically connected to the battery module 15 is fixedly provided through the top cover assembly 12. An upwardly extending fastening groove 111 is integrally formed on the bottom surface of the outer shell 11. An interface electrically connected to the battery module 15 is also fixedly provided through the bottom surface of the outer shell 11. 112, the size of the snap-fit ​​groove 111 is the same as the size of the top cover assembly 12. The top cover assembly 12 includes a top cover plate 121 with the same size as the snap-fit ​​groove 111 and a connecting frame 122 fixedly disposed on the bottom surface of the top cover plate 121 with a threaded hole that can mate with the through hole of the lifting frame 113. The connecting frame 122 can be detachably connected to the lifting frame 113. In use, first install the battery block 1, install the battery module 15 inside the outer casing 11, and then connect the battery module 15 to the interface 112 at the bottom of the outer casing 11 through a wire. Remove the top cover assembly 12 and connect the battery module 15 to the plug 13 on the top cover assembly 12 through a wire. The connection of the battery module 15, the plug 13, and the interface 112 through wires are all prior art. Widely used in stacked batteries, the wiring connections are not described in detail here. Next, the top cover plate 121 of the top cover assembly 12 is placed over the opening on the top surface of the outer casing 11, and the connecting frame 122 below the top cover plate 121 of the top cover assembly 12 is attached to the lifting frame 113. Waterproof bolts are then inserted into the threaded holes on the connecting frame 122 and passed through the through holes on the lifting frame 113 to achieve a fixed connection between the connecting frame 122 and the lifting frame 113, thus completing the installation of the battery block 1. Multiple battery blocks 1 are then stacked. A control block 2 is then connected to the topmost battery block 2. The control block 2 can be used to control charging or output current. The control block 2 is existing technology and widely used in stacked batteries. Without going into further detail, the size of the snap-fit ​​groove 111 is the same as that of the top cover assembly 12. Therefore, after stacking the battery blocks 1, the gap between them is very small. The height of the lifting frame 113 is determined by the depth of the snap-fit ​​groove 111, and its size is adapted to the top cover assembly 12. Technicians can select snap-fit ​​grooves 111 of different depths according to waterproofing requirements. The snap-fit ​​groove 111 under the outer casing 11, in conjunction with the lifting frame 113 and the top cover plate 121 of the top cover assembly 12, works together to raise the positions of the interface 112 and the plug 13. Therefore, when used outdoors, if rainwater splashes onto the battery body, it is difficult for rainwater to enter between the closely fitting battery blocks 1. Even if a very small amount of rainwater enters the gap between the battery blocks 1,It also prevents access to the lifted frame 113, top cover 121, and snap-fit ​​groove 111, thus significantly improving waterproof performance. Furthermore, for outdoor use, it eliminates the need for an additional fully enclosed cast shell, resulting in lower manufacturing costs. Waterproofing tests show that, compared to the IP20 waterproof rating of conventional stacked batteries, this stacked battery achieves an IP55 waterproof rating. The bottom of the battery body is provided with a tray 3, which is convenient for supporting the battery body through the tray 3 and sealing the bottom of the battery body to prevent water from coming into contact with the battery body from the bottom and causing a short circuit. The bottom of the tray 3 is equipped with a support 4, which helps to raise the tray 3, thereby preventing water from contacting the bottom of the battery body, and allowing rainwater to drip off naturally, further improving the waterproof effect; The outer casing 11 has an upward groove 14 on its side wall, which is convenient for carrying battery blocks 1. When carrying battery blocks 1, both hands can be inserted into the upward groove 14 for carrying, making it easier to carry and exert force. At the same time, it will not cause the side wall of the outer casing 11 to bulge, and it saves more space when multiple battery blocks 1 are placed horizontally. The top surface of the outer casing 11 is formed with a boss 114. The boss 114 has an inclination of 5°-10°. The inclination of 5°-10° can achieve a better drainage effect, while preventing rainwater from entering in large quantities. When rainwater enters between the battery blocks 1, the boss 114 makes it difficult for the rainwater to continue to move inward, and it will gradually roll off the boss 114 automatically due to gravity, further improving the waterproof capability. A waterproof strip is provided between the inner wall of the connecting frame 122 and the outer wall of the lifting frame 113, which helps to fill the gap between the connecting frame 122 and the lifting frame 113 through the waterproof strip, thereby further improving the waterproof performance; An injection layer is formed between the inner wall of the connecting frame 122 and the outer wall of the lifting frame 113 through the threaded hole. This injection layer helps to seal the gap between the connecting frame 122 and the lifting frame 113, and seals the gap between the threaded hole, the through hole and the waterproof bolt, thereby further improving the waterproof performance. When injecting the adhesive, glass glue is used and it is cured at room temperature for 24 hours.

[0018] The working principle of this utility model is as follows: First, install the battery block 1 and install the battery module 15 inside the outer casing 11. Then, connect the battery module 15 to the interface 112 at the bottom of the outer casing 11 via wires. Remove the top cover assembly 12 and connect the battery module 15 to the plug 13 on the top cover assembly 12 via wires. The wire connections between the battery module 15, plug 13, and interface 112 are existing technologies widely used in existing stacked batteries; therefore, the details of the wire connections are not described here. Next, cover the opening on the top surface of the outer casing 11 with the top cover plate 121 of the top cover assembly 12, and ensure that the connecting frame 122 below the top cover plate 121 of the top cover assembly 12 is fitted together with the lifting frame 113. Then, use waterproof bolts to lock the bolts into the threaded holes on the connecting frame 122. By passing through the through hole on the lifting frame 113 to achieve a fixed connection between the connecting frame 122 and the lifting frame 113, the installation of the battery block 1 can be completed. When multiple battery blocks 1 are stacked, the snap-fit ​​groove 111 under the outer shell 11 cooperates with the lifting frame 113 and the top cover plate 121 of the top cover assembly 12 to lift the position of the interface 112 and the plug 13. Therefore, when used outdoors, if rainwater splashes on the battery body, it is difficult for rainwater to enter between the battery blocks 1 that are in contact with each other. Even if a very small amount of rainwater enters the gap between the battery blocks 1, it cannot contact the plug 13 and the interface 112 that are lifted by the lifting frame 113, the top cover plate 121 and the snap-fit ​​groove 111, thus greatly improving the waterproof performance. Moreover, outdoor use does not require an additional fully enclosed cast outer shell, resulting in lower manufacturing costs.
