[0039] like Figure 1 As shown, the battery box system 10 in one embodiment includes a plurality of battery box devices 11, and the plurality of battery box devices 11 are arranged side by side in sequence; in the present embodiment, the battery box device 11 includes two, and the two battery box devices 11 are arranged side by side. It can be understood that in other embodiments, the number of battery box devices 11 can be more than three, and the specific setting method can be reasonably selected according to actual conditions.

[0040] like Figure 2 As shown, in one embodiment, the battery box device 11 includes a frame 100 and a battery box 200. The battery box 200 is detachably inserted into the frame 100. The battery box 200 includes multiple battery boxes 200, and the multiple battery boxes 200 are independently arranged in sequence along the height direction of the frame 100.

[0041] Since the battery box 200 is detachably inserted into the rack 100, and multiple battery boxes 200 are independently arranged in sequence along the height direction of the rack 100, when a battery box 200 has a problem and needs maintenance, the operator can detach the battery box 200 with the problem that needs maintenance from the rack 100 for subsequent maintenance, without having to disassemble all other battery boxes 200 adjacent to the battery box 200 with the problem that needs maintenance, thereby greatly reducing the maintenance workload of the battery box device 11 and greatly improving the maintenance convenience of the battery box device 11. At the same time, by arranging multiple battery boxes 200 in the rack 100 in sequence along the height direction of the rack 100, the space occupied by the battery boxes 200 in the width direction of the rack 100 can be effectively saved.

[0042] Specifically in this embodiment, the racks 100 of the plurality of battery box devices 11 are arranged in parallel in sequence. Figure 2 As shown, for ease of understanding, in this embodiment, the length direction, width direction, and height direction of the rack 100 are defined as the straight line directions where the X-axis, the Y-axis, and the Z-axis are located, respectively.

[0043] In this embodiment, the battery box device 11 includes four battery boxes 200, and the four battery boxes 200 are independently arranged in sequence along the height direction of the rack 100; it can be understood that in other embodiments, the number of battery boxes 200 arranged in the battery box device 11 can be two, three or more than five, and the specific setting method can be reasonably selected according to actual conditions.

[0044] like Figure 3As shown, further, in one embodiment, the battery box 200 has a latch 210, and a limiting hole 110 is provided on the first side in the length direction of the rack 100, and the latch 210 can cooperate with the limiting hole 110 to guide the insertion and installation of the battery box 200 relative to the rack 100; in one embodiment, a plurality of limiting holes 110 are provided on the first side in the length direction of the rack 100, and the latches 210 of the plurality of battery boxes 200 correspond one by one to the plurality of limiting holes 110 respectively.

[0045] Since the battery box 200 has a latch 210 and a limiting hole 110 is provided on the first side in the length direction of the rack 100, the latch 210 can cooperate with the limiting hole 110, so as to guide the insertion and installation of the battery box 200 relative to the rack 100, so that the operator can apply force to the end of the battery box 200 facing itself to accurately move the battery box 200 to a preset position in the rack 100 without having to adjust the position of the battery box 200 in the rack 100, thereby greatly improving the assembly efficiency between the battery box 200 and the rack 100.

[0046] like Figure 4 and Figure 5 As shown, further, in one embodiment, the battery box 200 also includes a box body 220 and a battery cell 230. The box body 220 is detachably inserted into the frame 100. The box body 220 includes a first end 221 and a second end 222 that are arranged opposite to each other.
