[0002] As an important representative of modern energy storage technology, lithium batteries play a crucial role in fields such as mobile devices, electric vehicles, and energy storage systems. With the continuous progress of technology, the structural design technology of lithium batteries is also constantly developing, providing strong support for the performance improvement and wide application of lithium batteries.

[0003] In the prior art, lithium batteries usually adopt an integrated design, that is, battery monomers are combined into a battery pack through parallel or series-parallel methods. Although this design simplifies the manufacturing process, it also brings a series of problems. First, the maintenance cost is high. Because when a battery monomer fails, the entire battery pack needs to be replaced, which increases the maintenance burden on users. Second, the expandability is poor. The integrated design limits the flexible expansion of the battery pack and is difficult to meet the growing energy needs of users. Finally, the resource utilization rate is low. Since the faulty battery monomer cannot be replaced separately, the entire battery pack is discarded when some parts are still working normally, resulting in waste of resources.

[0024] Embodiment 1

[0025] As Figures 1-4 shown, this is the first embodiment of the present utility model. This embodiment provides a modular combined lithium battery that is easy to dissipate heat, including a plurality of lithium battery monomer modules 1. The lithium battery monomer module 1 includes a battery cell 101, a protection board 102, and an outer shell 103. The protection board 102 is respectively fixedly installed on the top and bottom of the battery cell 101. The outer shell 103 covers the outside of the battery cell 101 and the protection board 102. A standardized interface 2 is provided at the top of the outer shell 103. A connecting wire 3 is fixedly installed at the top of the standardized interface 2. Different battery cells 101 are connected through the connecting wire 3.

[0026] As Figure 1 and Figure 2 shown, the battery cell 101 is installed between two protection boards 102, and then the outer shell 103 is covered on the outermost side of the battery cell 101 and the protection board 102 to provide physical protection for the battery cell 101. At the same time, it is convenient for the connection and combination of multiple lithium battery monomer modules 1. Through holes corresponding to the standardized interface 2 are provided on the surface of the protection board 102. The connecting wire 3 is connected to the battery cell 101 by inserting into the standardized interface 2, and thus different battery cells 101 can be combined.

[0027] Embodiment 2

[0028] Refer to Figure 2 、 Figure 3 and Figure 4 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0029] In this embodiment, a status indicator light 4 is provided at the top of the outer shell 103. The outer shell 103 is set as a hollow structure. Slots 5 are provided on both opposite sides of the outer shell 103. The slots 5 are arranged in parallel and equidistantly. A heat dissipation mechanism 6 is provided between two lithium battery single modules 1. The heat dissipation mechanism 6 includes heat dissipation fins 601 and thermal grease 602. A number of heat dissipation fins 601 are fixedly installed on both sides of the lithium battery single module 1. The thermal grease 602 is filled between the heat dissipation fins 601 and the lithium battery single module 1. The heat dissipation fins 601 are inserted into the slots 5.

[0030] As Figure 2 、 Figure 3 and Figure 4 shown, a status indicator light 4 is provided on the outer shell 103 of each lithium battery single module 1, which is used to intuitively display the working state of the battery cell 101, such as charging, discharging, fault, etc. The status indicator light 4 is connected to the control circuit and performs corresponding flashing or color change according to the real-time working state of the battery cell 101, which is convenient for users to discover and handle problems in time. Through the setting of the heat dissipation mechanism 6, it can ensure that heat can be evenly and quickly transferred to the heat dissipation fins 601, thereby further improving the heat dissipation effect, reducing the heat generated by the battery during operation, and improving the safety and service life of the battery.

[0031] Embodiment 3

[0032] Refer to Figure 2 、 Figure 3 and Figure 4 , which is the third embodiment of the present utility model. This embodiment is based on the previous two embodiments.

[0033] In this embodiment, the outer shell 103 is made of metal material. The standardized interface 2 is set as a plug-in interface. A fixing groove 7 is provided on the side of the protection board 102 close to the battery cell 101.

[0034] As Figure 2 、 Figure 3 and Figure 4As shown in the figure, the housing 103 of the lithium battery single cell module 1 is made of metal material, which can improve the structural strength and heat dissipation performance of the module. The housing 103 can also be replaced according to actual needs, or lightweight materials such as plastics and composite materials can be selected to reduce the overall weight and cost. The two ends of the connecting wire 3 are respectively inserted into the standardized interfaces 2 at the tops of two adjacent lithium battery single cell modules 1 for parallel connection of multiple lithium battery single cell modules 1. This connection method enables flexible combination and disassembly between the modules, thus forming a lithium battery pack with flexible configuration to meet the requirements of different application scenarios.

[0035] During use, the battery cell 101 is installed between two protection plates 102, and then the housing 103 is wrapped around the outermost sides of the battery cell 101 and the protection plates 102. The two ends of the connecting wire 3 are respectively inserted into the standardized interfaces 2 at the tops of two adjacent lithium battery single cell modules 1 for parallel connection of multiple lithium battery single cell modules 1. When the battery is working, the status indicator 4 flashes or changes color accordingly according to the real-time working state of the battery cell 101. The heat generated by the battery is transferred to the heat dissipation fins 601 through the thermal grease 602.

[0036] In summary: Through the modular structure design, the flexible combination and disassembly of the lithium battery single cell module 1 are realized, greatly improving the convenience of maintenance. At the same time, the overall replacement cost is reduced, solving the problem of difficult maintenance brought by the traditional integrated design of lithium batteries. The modular design makes the energy density and configuration of the battery pack more flexible and diverse. The number and configuration method of the appropriate lithium battery single cell modules 1 can be selected according to actual needs, thus meeting the requirements of different application scenarios, effectively improving the utilization rate of resources, and solving the problem of poor scalability. By adding the status indicator 4, the working state of the battery cell 101 can be intuitively displayed, facilitating users to timely understand the working conditions of the lithium battery, improving the safety of use. At the same time, the setting of the heat dissipation mechanism 6 effectively improves the heat dissipation efficiency of the lithium battery, extends the service life of the lithium battery, and further improves the overall performance of the lithium battery.
