Description

Technical Field

[0001] This utility model belongs to the field of battery pack technology, and in particular relates to a battery module without end plates. Background Technology

[0002] With the ongoing global energy transition and green development, the electric vehicle market is expanding rapidly, placing increasingly higher demands on the performance of power batteries. Electricity, as a power source, has the advantage of zero emissions, and its power can be derived from renewable energy sources such as solar, wind, and hydropower. Electrification has become an important development direction for the automotive and construction machinery industries.

[0003] The structural strength and energy density of battery modules directly affect a vehicle's range and safety performance, making them a key area for technological breakthroughs. As a crucial component of the battery pack, improving the module's structural strength and energy density has a decisive impact on the overall performance of the battery pack.

[0004] Currently, commonly used battery modules (such as...) Figure 1 As shown, the battery pack typically consists of straps, battery cells, and end plates. A buffer pad is added between the battery cells, and the end plates and battery cells are connected together by straps. However, the positive and negative outputs of the existing module structure are limited to the two sides of the end plate by the end plate, and cannot be output from the other two sides along the length. Furthermore, the existing battery cell arrangement can only be parallel to the end plate. When the battery pack has a double-layer structure, the existing module needs additional support within the housing for fixation. This places high demands on the structural strength of the housing, affects the space utilization within the housing, reduces the energy density of the battery pack, and fails to meet usage requirements.

[0006] To achieve the above objectives, the present invention adopts a terminal plate-less battery module, comprising a battery module body, with two sets of battery module bodies arranged vertically. Each battery module body includes a cover, and multiple battery packs arranged side by side are disposed inside the cover. The battery module body also includes a sheet metal shell disposed outside the cover. Positive and negative outputs are respectively disposed on the outer sides of the two ends located on the same side of the cover. A module support member is disposed on the outer side of the sheet metal shell of the lower battery module body to facilitate the installation of the two battery module bodies.

[0007] Preferably, the module support includes a crossbeam with a concave shape disposed on the outside of the sheet metal housing, a support frame with a concave shape disposed above the crossbeam, and a mounting plate disposed below the outside of the sheet metal housing of the battery module body, the mounting plate being provided with a connecting screw and connected to the support frame.

[0008] Preferably, a limiting plate is provided in the gap between the upper and lower battery module bodies, and a connecting plate with a concave shape is provided above the limiting plate, with both ends of the connecting plate placed between the mounting plate and the crossbeam, respectively.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Examples, such as Figures 2-4 As shown, a terminal plate-less battery module includes a battery module body. Two sets of battery module bodies are arranged vertically, which to some extent optimizes the shortcomings of existing module installation. Specifically, the battery module body includes a cover 1, and multiple battery packs 2 are arranged side by side inside the cover 1. Of course, components for connecting their positive and negative terminals are also provided above the individual cells of adjacent battery packs 2, so that multiple battery packs 2 are connected in series. The battery module body also includes a sheet metal shell 3 set outside the cover 1. On the one hand, it can increase the overall strength of the battery module body, and on the other hand, it provides a prerequisite for the multi-layer structure of the module. At the same time, the arrangement of the cells inside the sheet metal shell 3 can be arranged according to the size of the cells and the actual working conditions, no longer limited by the position of the existing terminal plate. This greatly improves the practicality of the device; positive output 4 and negative output 5 are respectively set on the outer sides of both ends on the same side of the casing 1. For the positive output 4 and negative output 5, they are no longer limited to one side of the end plate and can output from either side, which makes it convenient for people to freely set up and install according to different usage needs and ensure usage requirements; on the outer side of the sheet metal casing 3 of the lower battery module body, there is a module support 6 to facilitate the installation of the upper and lower battery module bodies. The module support 6 provides convenient conditions for the connection and fixation between the two modules, so that there is no need to set up a support mechanism on the box, which can save space to a certain extent, improve the space utilization rate inside the box, and improve the system energy density;

[0021] In the above process: using the sheet metal shell 3 and the module support 6 set up on its outside, the multi-layer battery module body structure can be easily set up and installed. The operation is simple and convenient, and there is no need to make a structure in the battery box. To a certain extent, it can save space, improve the space utilization rate in the box, and improve the system energy density. The device is reasonably designed, simple in structure, easy to process, and can realize power output in multiple directions. It can also easily connect the battery modules under the double-layer structure, improve their stability, ensure the space utilization effect in the box, improve the functionality of the device, and meet the usage requirements.

[0022] To facilitate the installation and connection of the upper and lower battery module bodies, the module support 6 includes a concave-shaped crossbeam 61 located on the outside of the sheet metal housing 3. A concave-shaped support frame 62 is provided above the crossbeam 61. A mounting plate 63 is located on the lower outside of the sheet metal housing 3 of the upper battery module body. A connecting screw 64 is provided on the mounting plate 63 and connected to the support frame 62. Specifically, during installation, one battery module body can be placed in the box first, and then another battery module body can be placed on the first battery module body. It is important to ensure that the mounting plate 63 corresponds to the support frame 62. The connecting screw 64 is then used to connect the mounting plate 63 to the support frame 62. This design realizes a convenient connection of the multi-layer battery module body structure and eliminates the need for a structure in the battery box. To a certain extent, it can save space, improve the space utilization rate in the box, and improve the system energy density.

[0023] To ensure a more stable installation of the upper and lower battery modules, a limiting plate 7 is installed in the gap between them. Above the limiting plate 7 is a concave connecting plate 8, which is bolted to the upper battery module. This provides a prerequisite for the connection between the devices. The two ends of the connecting plate 8 are positioned between the mounting plate 63 and the crossbeam 61, respectively, so that the device can be stably connected under the action of the connecting screw 64 during installation, ensuring its effectiveness. Specifically, the lower battery module is placed inside the housing, and the limiting plate 7 is connected to the inside of the housing. Then, another set of battery modules is placed on top of the first battery module, ensuring that the connecting plate 8 can be fitted and installed to fit the limiting plate 7. This not only limits the installation position of the device but also provides a prerequisite for its stable installation, ensuring its functionality.

[0024] To further improve the rationality of the device setup, the limiting plate 7 has a concave bend 71 that matches the connecting plate 8. This bend can limit the position of the connecting plate 8 and provide sufficient installation conditions for the connecting plate 8, ensuring good installation stability and guaranteeing the performance.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
