The structure of each soft-pack battery module in the housing 5 is the same, but the arrangement direction and position are different. The structure of a single soft-pack battery module is described below.

[0021] The structure of a single soft pack battery module is as follows: Figure 6 As shown, it mainly includes a plurality of soft-packed battery cells 1 stacked up and down, a battery cell frame 2 and a bus bar 3. Among them, the structure of a single soft-packed battery cell 1 is as follows Figure 1 As shown, the tabs 11 (positive tab and negative tab) of the soft-pack battery cell 1 face one side. The structure of the battery cell frame 2 is as follows Figure 2 As shown, the cell frame 2 in this embodiment is composed of two separate half-frame structures, and the two half-frame structures are spaced apart and arranged facing each other according to the width of the soft-pack cell 1.

Figure 3 With the direction as a reference, the left and right sides of the main board 31 are divided into two columns, and each column is provided with a plurality of tab sockets 32 at intervals. The number and position of the tab sockets 32 in the same column respectively correspond to the tabs 11 of each soft-pack battery cell 1 in the battery cell frame 2. The bus 3 is fixedly connected to the battery cell frame 2, and the tabs 11 of the soft-pack battery cell 1 in each slot extend from the corresponding tab sockets 32 of the bus 3 and are connected to the bus 3. A plurality of soft-pack battery cells 1 are stacked in a soft-pack battery cell module. In the present embodiment, there are 9 soft-pack battery cells 1 in a soft-pack battery cell module. The 9 soft-pack battery cells 1 are divided into 3 battery cell groups from top to bottom, that is, 3 adjacent soft-pack battery cells 1 located at the upper part are the upper battery cell group, 3 adjacent soft-pack battery cells 1 located in the middle part are the middle battery cell group, and 3 soft-pack battery cells 1 located at the lower part are the lower battery cell group. The 3 soft-pack battery cells 1 in each battery cell group are connected in parallel, and the upper and lower adjacent battery cell groups are connected in series.

To facilitate the routing and fixing of the position of the connecting wire, a plurality of threading frames 34 are provided on the outer surface of the main board 31 between the two columns of the pole ear sockets 32.

[0023] Based on the above-mentioned soft-pack battery module, a 3.5U48V150Ah power supply is formed. A total of 45 soft-pack battery cells 1 are connected in a way of 3 in parallel and 15 in series, which can be divided into five soft-pack battery modules, and each soft-pack battery module has 9 soft-pack battery cells 1. Figures 7 to 16 As shown, when the five soft-pack battery modules are arranged in the housing 5, the first vertical row of soft-pack battery modules A1 and the second vertical row of soft-pack battery modules A2 are arranged in a row front to back, making full use of the longitudinal space inside the housing 5 to form the vertical row of soft-pack battery modules. The busbars 3 of the first vertical row of soft-pack battery modules A1 and the second vertical row of soft-pack battery modules A2 are both facing the side of the panel 4, which is convenient for wiring between the soft-pack battery modules; and the first horizontal row of soft-pack battery modules B1, the second horizontal row of soft-pack battery modules B2, and the third horizontal row of soft-pack battery modules B3 are also arranged side by side to form a separate row, and the busbars 3 of the three horizontal rows of soft-pack battery modules are all facing the side of the vertical soft-pack battery modules. Figure 8 As shown, a cover plate 6 is provided on the top of the vertical soft-pack battery cell module and the horizontal soft-pack battery cell module respectively. The cover plate 6 is provided with a heat dissipation hole. The upper part where the heat dissipation hole is located is raised to form a wire passing frame 61 for threading the wire.

[0024] Following the above, Fig.10 As shown, a first partition plate 7 is provided between the panel 4 and the busbar 3 of the first vertical row of soft-pack battery modules A1. Fig.14 As shown, a third partition plate 9 is provided between the busbar 3 of the second vertical row of soft-pack cell modules A2 and the tail end of the first vertical row of soft-pack cell modules A1, and a second partition plate 8 is provided between the vertical row of soft-pack cell modules and the horizontal row of soft-pack cell modules. The partition plates are used to reasonably divide the internal space and fix each soft-pack cell module to the housing 5. The structure of the first partition plate 7 is as shown in FIG. Fig.11 As shown, the first partition plate 7 includes a main connection plate 71 parallel to the panel 4, the left side of the main connection plate 71 is bent outward to form a first ear plate 72 perpendicular to the main connection plate 71, and a fixing hole is provided on the first ear plate 72. The left and right sides of the upper end and the left and right ends of the lower end of the main connection plate 71 are respectively bent inward to form first fixing parts 73 perpendicular to the main connection plate 71, and a fixing hole is provided on each first fixing part 73. The first partition plate 7 is placed in front of the bus 3 of the first longitudinal row of soft-pack battery cell modules A1, and the upper and lower first fixing parts 73 clamp the battery cell frame 2. The first longitudinal row of soft-pack battery cell modules A1 can be fixedly connected to the casing 5 through the first fixing parts 73, and fixedly connected to the panel 4 through the first ear plate 72. The structure of the third partition plate 9 is similar to that of the first partition plate 7, and the first ear plate 72 is cancelled on the third partition plate 9. The structure of the second partition plate 8 is as shown in FIG. Fig.12As shown, its cross section is L-shaped and can be divided into a front partition 81 parallel to the panel 4 and a side partition 82 perpendicular to the panel 4. The front partition 81 is used to separate the first horizontal row of soft-pack battery modules B1 from the panel 4, and the side partition 82 is used to separate the horizontal row of soft-pack battery modules from the vertical row of soft-pack battery modules. The right side of the front partition 81 is bent outward to form a second ear plate 83 perpendicular to the front partition 81, and a fixing hole is provided on the second ear plate 83.

The second fixing portion 84 plays the role of fixing the horizontal row of soft-pack battery modules and fixing them to the housing 5. In order to facilitate the lead-out of the lead-out wires in the horizontal row of soft-pack battery modules, a notch 85 is also provided at the top of the connection between the side partition 82 and the front partition 81.

[0025] like Figure 7 As shown, for the convenience of wiring, in this embodiment, the positive output port 41 and the negative output port 42 on the panel 4 are set at the right end of the panel 4. After the five soft-pack battery modules are connected in series and parallel, the positive main wiring (or negative main wiring) of the power supply is led out from the first vertical row of soft-pack battery modules A1, and the negative main wiring (or positive main wiring) of the power supply is led out from the first horizontal row of soft-pack battery modules B1. According to the structure and installation position of the first partition board 7 and the second partition board 8 designed in this embodiment, Fig.10 It can be seen that the outer surface of the first partition plate 7 protrudes from the outer surface of the front partition plate 81 in the second partition plate 8, so that the positive power supply line drawn from the first vertical row of soft-pack battery modules A1 can extend from the gap between the first partition plate 7 and the second partition plate 8, and run along the outer surface of the front partition plate 81 of the second partition plate 8 to connect to the positive output port 41 on the panel 4. The negative power supply line drawn from the first horizontal row of soft-pack battery modules B1 can extend from the notch 85, and run along the outer surface of the front partition plate 81 of the second partition plate 8 to connect to the negative output port 42 on the panel 4.

[0026] The present invention utilizes the designed busbar 3 and battery cell frame 2, and cooperates with the structural design inside the casing 5, so that the routing of the power supply becomes reasonable and the internal space of the casing 5 is fully utilized; the cover plate 6 arranged on the top of the soft-pack battery cell module has the functions of facilitating routing, fixing the soft-pack battery cell module and dissipating heat; the inside of the casing 5 adopts a reasonable layout with two soft-pack battery cell modules arranged vertically on the left and three soft-pack battery cell modules arranged horizontally on the right, which maximizes the use of the space inside the casing 5 and takes into account the convenience of routing. The present invention also maintains a certain safety distance between the terminals of the soft-pack battery cell module and the casing 5 through the structural design of the partition plate.

[0027] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
