Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, specifically to a modular MBC structure. Background Technology

[0002] In recent years, with the rapid development of the new energy industry, lithium-ion power batteries have become one of the mainstream energy sources for energy storage systems. Due to their advantages such as high efficiency, environmental friendliness and long lifespan, lithium-ion power batteries are widely used in energy storage solutions for grid energy storage, new energy vehicles and renewable energy systems. This trend requires them not only to have high energy density and high power density, but also to have excellent thermal management performance and high safety. Therefore, the development of new lithium-ion power batteries is of great significance.

[0003] The design process from module to PACK requires huge R&D investment and trial and error risks. Therefore, a platform-based and reliable PACK solution is particularly important in the design. Currently, the industry designs modules first and then performs conventional integration design, which results in long development cycles, high costs, and a high rate of trial and error.

[0004] To address this, a modular MBC structure is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a modular MBC structure in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A modular MBC structure includes a battery rack and battery modules. Four sets of bottom beams are fixedly installed on the inner bottom of the battery rack, and the surface of the bottom beams is provided with a second through hole. Lateral support components are fixedly installed at both ends of the battery modules, and the battery modules are stacked sequentially from bottom to top through the lateral support components at the ends of the battery modules. Screws are inserted into the battery rack, the lateral support components, and the second through holes, and nuts are threaded on both ends of the screws for locking at both ends. A heat insulation plate is installed on the surface of the battery rack and between the vertical battery modules.

[0008] Furthermore, the battery rack includes a base frame, and four sets of base beams are fixedly installed on the top surface of the base frame. Several sets of vertical frames are fixedly installed on the top surface of the base frame, and a top frame is fixedly installed on the top of the vertical frames. A first through hole is opened on the surface of the base frame and the top frame.

[0009] Furthermore, the lateral support assembly includes support side plates fixedly installed on the front and rear end faces of the battery module, and a positioning protrusion is fixedly installed on the bottom surface of the support side plate. A third through hole is opened in the support side plate and the positioning protrusion, and the top of the support side plate and the third through hole are inserted into each other.

[0010] Furthermore, the positioning protrusion on the bottom surface of the support side plate of the lowest battery module end face is inserted into the second through hole on the surface of the bottom beam.

[0011] Furthermore, the nuts and the two ends of the screw are threaded together, and the nuts at both ends of the screw are tightly fitted to the end faces of the base frame and the top frame, respectively.

[0012] Furthermore, the heat insulation board is made of mica cloth and high-temperature refractory fabric made of high-temperature resin composite material.

[0013] The beneficial effects of this utility model are as follows:

[0014] By locking four bottom beams onto the inner bottom of the battery rack, and using lateral support components at the ends of the battery modules, the battery modules and lateral support components are stacked sequentially from bottom to top. This creates a safe electrical clearance and assembly space between two vertically adjacent battery modules. A screw passes through the battery rack, multiple lateral support components, and the second through hole on the surface of the bottom beams from top to bottom. Nuts are threaded onto both ends of the screw, thereby locking both ends of the entire battery module. This ensures overall strength and constraint, guaranteeing the strength and stability of the overall structure. By replacing the traditional metal insulation structure with a heat insulation plate, system space is saved, and safety is improved, forming an efficient, safe, and space-saving battery module integration method.

[0025] like Figures 1 to 5As shown, a modular MBC structure includes a battery rack 1 and a battery module 3. Four sets of bottom beams 2 are fixedly installed on the inner bottom of the battery rack 1, and the surface of the bottom beams 2 is provided with a second through hole 21. Lateral support components 4 are fixedly installed at both ends of the battery module 3, and the battery module 3 is formed by stacking the lateral support components 4 at the ends of the battery module 3 from bottom to top. Screws 5 are inserted into the battery rack 1, the lateral support components 4 and the second through hole 21, and nuts 6 are threaded on both ends of the screws 5 for locking at both ends. A heat insulation plate 7 is installed between the surface of the battery rack 1 and the vertical battery module 3. More specifically, by locking four bottom beams 2 onto the inner bottom of the battery rack 1, and using the lateral support components 4 at the ends of the battery modules 3, the battery modules 3 and the lateral support components 4 are stacked sequentially from bottom to top, so that two vertically adjacent sets of battery modules 3 form a safe electrical clearance and assembly space. The screw 5 passes through the second through hole 21 on the surface of the battery rack 1, multiple sets of lateral support components 4 and bottom beams 2 from top to bottom. Nuts 6 are threaded onto both ends of the screw 5, thereby locking both ends of the entire battery module 3, ensuring overall strength and constraint, and ensuring the strength and stability of the overall structure. The heat insulation plate 7 replaces the traditional metal isolation structure.

[0026] The battery rack 1 includes a base frame 101, and four sets of base beams 2 are fixedly installed on the top surface of the base frame 101. Several sets of vertical frames 102 are fixedly installed on the top surface of the base frame 101, and a top frame 103 is fixedly installed at the top of the vertical frames 102. A first through hole 104 is opened on the surface of the base frame 101 and the top frame 103. More specifically, the battery module 3 can be installed through the base frame 101, the top frame 103, and the vertical frames 102 between the base frame 101 and the top frame 103.

[0027] The lateral support assembly 4 includes support side plates 401 fixedly installed on the front and rear end faces of the battery module 3. A positioning protrusion 402 is fixedly installed on the bottom surface of the support side plate 401. A third through hole 403 is formed within the support side plate 401 and the positioning protrusion 402, and the tops of the support side plate 401 and the third through hole 403 are interlocked. More specifically, the interlocking of the positioning protrusion 402 on the bottom surface of the support side plate 401 with the third through hole 403 on the top of the other support side plate 401 creates a safe electrical clearance and assembly space for the vertically oriented battery module 3.

[0028] The positioning protrusion 402 on the bottom surface of the support side plate 401 of the bottom battery module 3 is inserted into the second through hole 21 on the surface of the bottom beam 2. More specifically, the positioning protrusion 402 on the bottom surface of the support side plate 401 of the bottom battery module 3 can be positioned and placed through the second through hole 21 on the surface of the bottom beam 2, and can be inserted into it through the screw 5.

[0029] The nuts 6 are threaded onto both ends of the screw 5, and the nuts 6 at both ends of the screw 5 are tightly fitted to the end faces of the base frame 101 and the top frame 103, respectively. More specifically, the nuts 6 threaded onto both ends of the screw 5 enable the battery modules 3 inside the battery rack 1 to be stacked and locked.

[0030] The heat insulation plate 7 is made of mica cloth and high-temperature refractory fabric made of high-temperature resin composite material. More specifically, the mica cloth and high-temperature refractory fabric are made of high-temperature resin composite material, which can withstand a high temperature of 1200 degrees Celsius for more than half an hour. The temperature on its back is only about 500 degrees Celsius. With the air medium, heat can be radiated to the back of the heat insulation plate, ensuring that the module does not thermally runaway. In addition, the heat insulation plate 7 prevents heat propagation between battery clusters.

[0031] In summary: By locking the four bottom beams 2 onto the inner bottom of the battery rack 1, and using the lateral support components 4 at the ends of the battery modules 3, the battery modules 3 and the lateral support components 4 are stacked sequentially from bottom to top, creating a safe electrical clearance and assembly space between two vertically adjacent battery modules 3. The screw 5 passes through the second through hole 21 on the surface of the battery rack 1, multiple lateral support components 4, and bottom beams 2 from top to bottom. Nuts 6 are threaded onto both ends of the screw 5, thereby locking both ends of the entire battery module 3, ensuring overall strength and constraint, and ensuring the strength and stability of the overall structure. The heat insulation plate 7 replaces the traditional metal isolation structure.
