Description

Technical Field

[0001] This utility model relates to the field of battery module technology, and in particular to a stacked high-voltage battery module structure. Background Technology

[0002] As living standards improve, people are using more and more home appliances. To meet the application needs of people in various daily scenarios at home, multi-stacked energy storage systems have emerged on the market to solve power shortages and improve power supply reliability.

[0003] However, existing energy storage systems are mostly composed of different numbers of battery boxes and control boxes. The battery modules are locked together by locking mechanisms. The locking mechanism of stacked systems is complex and inconvenient to install. Moreover, each group of energy storage units is tightly attached together. In the high temperature environment of summer, the heat cannot be dissipated in time, which affects the battery life and can easily lead to safety accidents.

[0004] Therefore, in order to solve the above problems, it is urgent to develop a stacked high-voltage battery module structure. Utility Model Content

[0005] To address the shortcomings of existing production technologies, the applicant provides a stacked high-voltage battery module structure, thereby improving module installation efficiency, saving installation labor costs, reserving heat dissipation channels between modules, increasing battery lifespan, and improving the safety of the energy storage system.

[0006] The technical solution adopted by this utility model is as follows: A stacked high-voltage battery module structure for stacking and connecting multiple high-voltage battery modules, comprising:

[0007] The first connector and the second connector are located at opposite ends on one side of the high-voltage battery module and are used for connection between the upper and lower high-voltage battery modules.

[0008] The first guide box and the second guide box are located at opposite ends on the other side of the high-voltage battery module to guide the stacking of the high-voltage battery modules.

[0009] Heat dissipation channels are located on both sides of the high-voltage battery module to dissipate heat through airflow;

[0010] The heat dissipation fins are located between the guide box and the connector to enhance heat dissipation.

[0011] In one embodiment, the first guide box and the second guide box are matched with each other, and when stacked, the first guide box passes through and falls into the interior of the second guide box.

[0012] In one embodiment, the first guide box and the second guide box are coarsely positioned by external inner and outer chamfers during the stacking process.

[0013] In one embodiment, the heat dissipation channel is structured as a downward-facing arc-shaped opening to serve as a handling handle for workers to handle and stack high-voltage battery modules.

[0014] In one embodiment, an explosion-proof valve is also included, disposed on the high-voltage battery module, for releasing pressure when the internal pressure of the battery module is too high, thereby improving safety.

[0015] In one embodiment, a fixing screw hole is provided on the side of the guide box. A bolt passes through the fixing screw hole in sequence through the second guide box and the first guide box to achieve a fixed connection between the upper and lower high-voltage battery modules.

[0016] In one embodiment, the heat dissipation teeth are arranged along the length of the battery module to facilitate airflow entering after passing through the heat dissipation channel, thereby increasing the heat dissipation area and improving heat dissipation efficiency.

[0017] During stacking, the upper high-voltage battery module is positioned by the first guide box at its bottom cooperating with the second guide box at the top of the lower high-voltage battery module until the upper and lower high-voltage battery modules come into contact and are fixedly connected by fixing screw holes and bolts. The heat dissipation channel and heat dissipation teeth work together to allow airflow to enter from the heat dissipation channel on one side, pass through the heat dissipation teeth and exit from the heat dissipation channel on the other side, thereby achieving heat dissipation of the battery module.

[0018] The beneficial effects of this utility model are as follows:

[0019] This utility model has a compact and reasonable structure and is easy to operate. With the cooperation of the upper and lower guide boxes, when stacking and installing, the first guide box and the second guide box work together to guide from coarse positioning to fine positioning to realize blind insertion connection between the upper and lower modules, which is convenient for operators and has high stacking and assembly efficiency.

[0020] This utility model also has the following advantages:

[0021] (1) The present invention also provides a fixing screw hole on the guide box. The fixing bolt passes through the fixing screw hole and the guide box to fix the upper and lower modules tightly, improve the installation efficiency and increase the stability between the modules.

[0022] (2) The present invention reserves a heat dissipation channel between the upper and lower modules and works in conjunction with the heat dissipation teeth to increase the heat dissipation effect, thereby increasing the battery life and improving the safety of the energy storage system; in addition, the heat dissipation channel can also be used as a handling handle to improve practicality.

[0034] like Figures 1-4 The accompanying drawing shows a structural diagram of a stacked high-voltage battery module structure according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0035] In this embodiment, a stacked high-voltage battery module structure includes a first connector 1, a first guide box 2, an explosion-proof valve 3, a heat dissipation channel 4, a second guide box 5, a second connector 6, heat dissipation teeth 7, and a fixing screw hole 8.

[0036] In some embodiments, a stacked high-voltage battery module structure is used for stacking connections between multiple high-voltage battery modules, including:

[0037] The first connector 1 and the second connector 6 are disposed at opposite upper and lower ends on one side of the high-voltage battery module and are used for connection between the upper and lower high-voltage battery modules.

[0038] The first guide box 2 and the second guide box 5 are disposed at opposite ends on the other side of the high voltage battery module to guide the stacking of the high voltage battery modules.

[0039] Heat dissipation channel 4 is located on both sides of the high-voltage battery module and is used to dissipate heat through airflow.

[0040] Heat dissipation teeth 7 are located in the middle of the guide box and the connector to enhance heat dissipation.

[0041] In one specific embodiment, the first guide box 2 and the second guide box 5 are matched with each other, and when stacked, the first guide box 2 passes through and falls into the interior of the second guide box 5.

[0042] In one specific embodiment, the first guide box 2 and the second guide box 5 are coarsely positioned by external inner and outer chamfers during the stacking process.

[0043] In one specific embodiment, the heat dissipation channel 4 has a downward-facing arc-shaped opening to serve as a handling handle for workers to handle and stack the high-voltage battery modules.

[0044] In one specific embodiment, an explosion-proof valve 3 is also included, which is disposed on the high-voltage battery module and is used to release pressure when the internal pressure of the battery module is too high, so as to improve safety.

[0045] In one specific embodiment, a fixing screw hole 8 is provided on the side of the guide box. A bolt passes through the fixing screw hole 8 in sequence through the second guide box 5 and the first guide box 2 to achieve a fixed connection between the upper and lower high-voltage battery modules.

[0046] In one specific embodiment, the heat dissipation teeth 7 are arranged along the length of the battery module to facilitate airflow entering after passing through the heat dissipation channel 4, thereby increasing the heat dissipation area and improving heat dissipation efficiency.

[0047] In practical applications, the stacking method of this application is as follows:

[0048] The high-voltage battery module located above is lifted by the heat dissipation channels 4 on both sides, and then slowly lowered from directly above the high-voltage battery module located below.

[0049] The first guide box 2 contacts the second guide box 5, and rough positioning is achieved by chamfering the inner and outer corners;

[0050] The upper high-voltage battery module continues to fall, and the first guide box 2 completely enters the second guide box 5. The first guide box 2 and the second guide box 5 work together to achieve precise positioning. At this time, the bottom of the upper high-voltage battery module contacts the top of the lower high-voltage battery module.

[0051] The side of the guide box is also provided with fixing screw holes 8. Bolts are passed through the fixing screw holes 8 in sequence through the second guide box 5 and the first guide box 2 to fix the upper and lower high voltage battery modules and complete the stacking connection between the upper and lower high voltage battery modules.

[0052] This also includes the following heat dissipation methods:

[0053] After the upper and lower high-voltage battery modules are stacked and connected, they are not completely fitted together due to the presence of heat dissipation channel 4 and heat dissipation tooth 7.

[0054] Heat dissipation channels 4 are provided on both sides for airflow, and heat dissipation teeth 7 are provided along the length of the module at the middle position between the guide box and the connector. Airflow enters from the heat dissipation channel 4 on one side, passes through the heat dissipation teeth 7, and then exits from the heat dissipation channel 4 on the other side. Throughout the process, the battery module carries away battery heat through natural cooling airflow.

[0055] The present invention has a reasonable structure and is easy to operate. By adding heat dissipation channel 4 and working in conjunction with the heat dissipation teeth 7, the heat dissipation effect is greatly improved compared with the traditional stacking structure, the battery life is increased and the safety of the energy storage system is improved. At the same time, the heat dissipation channel 4 can also be used as a handling handle to facilitate stacking by staff.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
