In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0028] This embodiment provides a mobile energy storage vehicle, and the specific scheme is described through the following embodiments.

[0029] Figure 1 It is a schematic diagram of the three-dimensional structure of the box body in the mobile energy storage vehicle of this embodiment.

[0030] See also Figure 1As shown, the mobile energy storage vehicle of this embodiment includes a vehicle body (not shown in the figure) and a box body 1. The vehicle body includes a front and a frame. The frame is connected to the front. The box body 1 is arranged on the frame. The box body 1 is provided with various devices for external energy supply, so that the mobile energy storage vehicle has the function of mobile energy supply, can quickly reach the area where electricity is needed, supply electricity to it, and meet its electricity demand.

[0031] The box 1 can be implemented as a container of standard size to save costs. Moreover, the standardization of the size of the box 1 makes the box 1 universal, which can better meet the transportation requirements and adapt to more transportation tools.

[0032] Practically, the box body 1 is a standard 20-foot container.

[0033] In some other embodiments, the box body 1 may be a 40-foot container. Accordingly, for containers of different standard sizes, the number of battery clusters loaded therein and the amount of power stored therein are also different.

[0034] A first equipment compartment 11 is provided at one end of the box body 1. A second equipment compartment 12 is provided at the other end of the box body 1. A battery compartment 13 is provided between the first equipment compartment 11 and the second equipment compartment 12.

[0035] A plurality of battery clusters 14 are arranged in the battery compartment 13. In practice, the plurality of battery clusters 14 are arranged in a matrix, that is, there is no aisle for people to pass through in the battery compartment, which effectively improves the space utilization rate in the compartment. Placing as many battery clusters 14 as possible in a limited space is also conducive to increasing the total amount of energy storage. Each battery cluster 14 includes a plurality of battery packs.

[0036] It can be understood that the battery compartment 13 is disposed in the middle of the box body 1, which is beneficial to protecting the battery cluster 14 in the battery compartment 13 and also makes the center of gravity of the entire box body 1 roughly close to the center position.

[0037] Practically, the second equipment compartment 12 is close to the front of the vehicle body. Along the length direction of the box body 1, the length of the first equipment compartment 11 is greater than the length of the second equipment compartment 12. Equivalently, the area of ​​the first equipment compartment 11 is greater than the area of ​​the second equipment compartment 12. The space of the first equipment compartment 11 is greater than the space of the second equipment compartment 12. It can be understood that because the second equipment compartment 12 occupies a smaller space in the box body 1, the battery compartment 13 provided between the first equipment compartment 11 and the second equipment compartment 12 is closer to the front position of the vehicle body, so that the center of gravity of the box body 1 is close to the center of the vehicle body, which is more conducive to safe and stable driving of the vehicle body.
