[0024] In one of the preferred embodiments, the container 1 is in the shape of a vertical rectangular parallelepiped, and a plurality of battery box modules 2 are stacked to reduce the floor space and provide a reasonable layout.

[0025] In one of the preferred embodiments, the interior of the container 1 is divided into a main storage space and an auxiliary storage space by a vertical partition 116. The width of the main storage space is greater than that of the auxiliary storage space. The main storage space is provided with a plurality of battery box modules 2, and the auxiliary storage space is provided with a high-voltage box 4 and a chiller 3. Battery box modules 2 of comparable width are selected to match the width of the main storage space, and a plurality of battery box modules 2 are stacked and arranged. The narrower high-voltage box 4 and the chiller 3 are placed in the auxiliary storage space, so that the internal space of the container 1 can be reasonably utilized.

A first box door 12 is arranged at the front end of the main accommodating space, and a third box door 14 is arranged at the rear end. The first box door 12 is convenient for installing and repairing the connection between the battery box module 2 and the liquid supply channel 31 and the liquid return channel 32, and the third box door 14 is convenient for removing or loading the battery box module 2 into the container 1 respectively. In addition, when the heat dissipation effect in the container 1 is poor, the first box door 12 and the third box door 14 can be opened to achieve rapid heat dissipation in the container 1 to avoid heat spread and the like.

[0027] In one of the preferred embodiments, a mounting frame 111 is arranged in the main accommodation space, and a plurality of groups of straps 114 matching the drawer 17 are arranged on the mounting frame 111. The drawer 17 is supported and mounted on the mounting frame 111 by the straps 114, that is, there is an installation space for the battery box module 2 between two adjacent groups of straps 114. The drawer 17 drives the battery box module 2 in and out of the installation space. A plurality of battery box modules 2 can be modularly integrated by using the mounting frame 111, and then the integrated whole can be loaded into or removed from the container 1.

Preferably, the chiller is fixed in the auxiliary accommodating space between the first ventilation window 15 and the second ventilation window 16 through a second bracket 113.

[0031] Furthermore, the high-voltage box 4 is installed in the auxiliary accommodation space through the first bracket 112 , which fixes the high-voltage box 4 on the one hand and leaves enough heat dissipation space around the high-voltage box 4 on the other hand.

[0032] In one of the preferred embodiments, the inner diameter of the return liquid channel 32 is larger than the inner diameter of the liquid supply channel 31. Preferably, the inner diameter of the return liquid channel 32 is twice the inner diameter of the liquid supply channel 31, so as to facilitate the circulation of the coolant through the pressure difference inside the battery box module 2.
