Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a bottom-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 bottom-mounted, leak-proof, stacked battery that is simple to manufacture, has good sealing properties, and is easy to seal.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bottom-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 and an upper protrusion integrally formed on the top of the outer shell. A connecting frame that retracts into the outer shell is fixedly connected to the inner wall of the bottom of the outer shell. A grooved battery cell structure that can cooperate with the upper protrusion is detachably installed on the bottom surface of the connecting frame. A plug that is electrically connected to the grooved battery cell structure is penetrated through the top surface of the upper protrusion.

[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 grooved cell structure includes a grooved chassis that can be detachably installed on the bottom surface of the connecting frame and can cooperate with the upper protrusion, and a battery module that is fixedly installed on the grooved chassis. The battery module is electrically connected to the plug, and an interface that is electrically connected to the battery module is also installed through the grooved chassis.

[0010] A further improvement is that the grooved chassis includes a connecting plate that can be detachably installed on the bottom surface of the connecting frame and an upwardly extending upper groove integrally formed on the bottom surface of the connecting plate, the upper groove having the same dimensions as the upper protrusion.

[0011] A further improvement is that the bottom surface of the outer shell is integrally formed with a downwardly extending water-blocking step.

[0012] A further improvement is that a waterproof sealing gasket is provided between the connecting frame and the connecting plate.

[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: During the production of this utility model, the outer shell and the connecting frame on the outer shell are formed, and the battery module is installed on the grooved base. After the interface and plug are connected to the battery module, the grooved base is locked into the connecting frame with waterproof bolts to form a battery block. When multiple battery blocks are stacked, the upper groove of the grooved base cooperates with the upper protrusion on the outer shell to insert the upper protrusion into the upper groove, thereby raising the position of the interface and plug. Thus, 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 plug and interface raised by the upper protrusion and upper groove, thereby greatly improving the waterproof performance. Moreover, there is no need to equip an additional fully enclosed cast outer shell, 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 1-7As shown, the technical solution adopted in this specific embodiment is: a bottom-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 a housing 11 and an upper protrusion 12 integrally formed on the top of the housing 11. A connecting frame 111 that retracts into the housing 11 is fixedly connected to the bottom inner wall of the housing 11. A grooved cell structure 15 that can cooperate with the upper protrusion 12 is detachably installed on the bottom surface of the connecting frame 111. The grooved cell structure 15 includes a grooved base 151 that can cooperate with the upper protrusion 12 and is detachably installed on the bottom surface of the connecting frame 111, and a battery module 1 fixedly installed on the grooved base 151. 52. The recessed base 151 includes a connecting plate 21 detachably mounted on the bottom surface of the connecting frame 111 and an upwardly extending upper recess 22 integrally formed on the bottom surface of the connecting plate 21. The upper recess 22 has the same dimensions as the upper protrusion 12. The battery module 152 is electrically connected to the plug 13. An interface 153 for electrical connection to the battery module 152 is also installed through the recessed base 151. A plug 13 for electrical connection to the recessed cell structure 15 is provided through the top surface of the upper protrusion 12. In use, the battery block 1 is first installed, and the battery module 152 is fixed to the upper surface of the recessed base 151. Then, the interface 153 and the battery module 152 are connected by wires, and the plug 13 is connected to the battery module 152 by wires. The connections of 52, plug 13, and interface 153 are all existing technologies widely used in existing stacked batteries. Specific details regarding wire connections are not provided here. Subsequently, the recessed base 151 with battery module 152 is inserted into the housing 11, fitting it against the connecting frame 111 at the bottom of the housing 11. Waterproof bolts are used to lock the connecting frame 111 and the recessed base 151, thus inserting the recessed base 151, battery module 152, and interface 153 into the housing 11 to form battery block 1. Multiple battery blocks 1 are then stacked, with plug 13 inserted into the interface 153 of the battery block 1, and the upper protrusion 12 inserted into the upper recess 22. Since the size of the upper protrusion 12 is similar to that of the upper recess 22... Since the two are identical, the gap between them is very small. Then, the charging or output current can be controlled by the control block 2. The control block 2 is existing technology and widely used in stacked batteries, so it will not be described in detail here. When multiple battery blocks 1 are stacked, the upper groove 22 of the recessed base 151 cooperates with the upper protrusion 12 on the outer casing 11, allowing the upper protrusion 12 to insert into the upper groove 22. This raises the position of the interface 153 and the plug 12. 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 will be absorbed by the upper protrusion 12 and the upper groove 22.This design prevents rainwater from contacting the plug 12 and interface 153, which are raised by the upper protrusion 12 and upper groove 22, thus preventing short circuits and significantly improving waterproof performance. Furthermore, it eliminates the need for an additional fully enclosed cast casing, resulting in lower manufacturing costs. Waterproof testing shows that this stacked battery achieves an IP55 waterproof rating.

[0018] 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 bottom surface of the outer shell 11 is also integrally formed with a downwardly extending water-blocking step 112, which helps the outer shell 11 to better position the groove bottom plate 151, and also better keeps rainwater out. A waterproof sealing gasket is also provided between the connecting frame 111 and the connecting plate 21, which helps to further improve the sealing between the connecting frame 111 and the connecting plate 21 and further prevent rainwater from entering.

[0019] The working principle of this utility model is as follows: First, the battery block 1 is installed, and the battery module 152 is fixed to the upper surface of the recessed base 151. Then, the interface 153 and the battery module 152 are connected via wires, and the plug 13 is connected to the battery module 152 via wires. Next, the recessed base 151 with the battery module 152 is inserted into the outer casing 11, making it fit snugly against the connecting frame 111 at the bottom of the outer casing 11. Waterproof bolts are used to lock the connecting frame 111 and the recessed base 151, so that the recessed base 151, along with the battery module 152 and the interface 153, is installed into the outer casing 11 to form the battery block 1. Then, multiple battery blocks 1 are stacked, so that the interface 153 of the battery block 1 is inserted and connected by the plug 13, and the upper protrusion 12 is inserted into the upper recess 22. Since the upper protrusion 12 is the same size as the upper recess 22, the gap between them is very small. Then, the charging or output current can be controlled by the control block 2. The control block 2 is existing technology and is widely used in stacked batteries. It will not be described in detail here. When multiple battery blocks 1 are stacked, the upper groove 22 of the groove base 151 cooperates with the upper protrusion 12 on the outer shell 11 to insert the upper protrusion 12 into the upper groove 22. This raises the position of the interface 153 and the plug 12. 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, the upper protrusion 12 and the upper groove 22 raise the rainwater so that it cannot come into contact with the plug 12 and the interface 153 raised by the upper protrusion 12 and the upper groove 22, and a short circuit will not occur. This greatly improves the waterproof performance and eliminates the need for an additional fully enclosed cast outer shell, resulting in lower manufacturing costs.
