The staff can open the second refrigeration door 180 to repair the control module of the refrigeration structure 200. The staff can also open the second refrigeration door 180 and remove the upper wall panel 132 to inspect and replace the control module.

[0074] In the present application, the layout of the box body 100 structure of the mobile energy storage container is reasonable, and the refrigeration cabin 162 is arranged at the end of the box body 100 to reduce the heat transferred to the energy storage cabin 161 when the refrigeration structure 200 is in operation, and to facilitate the refrigeration structure 200 to cool the battery pack 300. The first refrigeration door body 170 and the second refrigeration door body 180 can improve the installation efficiency of the refrigeration structure 200. When the mobile energy storage container fails, the refrigeration pipeline of the refrigeration structure 200 can be repaired by opening the first refrigeration door body 170. The control module of the refrigeration structure 200 is repaired by opening the second refrigeration door body 180, thereby improving the maintenance efficiency of the mobile energy storage container.

[0075] See also Figures 1 to 5The present invention also includes a mobile energy storage container, which includes: any of the above-mentioned box body 100 structures, a refrigeration structure 200 and a battery pack 300. The refrigeration structure 200 is accommodated in the refrigeration cabin 162, the refrigeration pipeline of the refrigeration structure 200 is arranged corresponding to the first refrigeration door body 170, and the control module of the refrigeration structure 200 is arranged corresponding to the second refrigeration door body 180; the battery pack 300 is accommodated in the energy storage cabin 161; wherein, the refrigeration pipeline of the refrigeration structure 200 extends from the refrigeration cabin 162 into the energy storage cabin 161 to communicate with the battery pack 300 to cool the battery pack 300.

[0076] When the mobile energy storage container is in use, the refrigeration structure 200 cools the battery pack 300 through the refrigeration pipeline. The staff can open the second refrigeration door 180 to control the control module, thereby monitoring and adjusting the temperature of the battery pack 300 in real time.

[0077] When the refrigeration structure 200 of the mobile energy storage container needs maintenance, the staff can open the first refrigeration door 170, the second refrigeration door 180, and the upper wall panel 132 respectively to repair the refrigeration structure 200 such as the refrigeration pipeline and the control module, thereby improving the maintenance efficiency of the refrigeration structure 200.

[0078] When the mobile energy storage container is in use, the side wall 120, the end wall 130, the first partition wall 151, and the second partition wall 152 are connected to the frame structure 110 to protect the energy storage compartment 161. When the mobile energy storage container is impacted during transportation and use, the side wall 120, the end wall 130, the first partition wall 151, the second partition wall 152 and the frame structure can absorb the impact kinetic energy, protect the battery pack 300 in the energy storage compartment 161, prevent the battery pack 300 from catching fire or exploding due to the impact, and ensure the safety performance of the mobile energy storage container.

[0079] The utility model also includes a mobile energy storage vehicle, which includes: the mobile energy storage container and a vehicle body as described above. The mobile energy storage container is installed on the vehicle body. The mobile energy storage container and the vehicle body are detachably connected.

[0080] The vehicle body is used to carry the mobile energy storage container. The vehicle body can be connected to the transport vehicle to drive the mobile energy storage container to move. When the mobile energy storage vehicle is moving, the arrangement of the upper side wall panel 132 and the lower side wall panel 131 can effectively improve the structural strength of the mobile energy storage container and improve the impact resistance of the mobile energy storage container, thereby protecting the battery pack 300.

[0081] When the mobile energy storage vehicle reaches the destination during the transportation process, the mobile energy storage vehicle can be separated from the transport vehicle. This allows the mobile energy storage vehicle to provide power to the outside world. When the mobile energy storage vehicle needs to move, it only needs to connect the transport vehicle to the mobile energy vehicle to drive the mobile energy storage vehicle to move. This effectively improves the mobility efficiency of the mobile energy storage vehicle.

[0082] The first refrigeration door body 170 disposed on the side wall 120 and the second refrigeration door body 180 disposed on the end wall 130 can facilitate the staff to use, inspect and repair the refrigeration equipment, thereby effectively improving the use efficiency of the mobile energy storage vehicle and ensuring the safety of the mobile energy storage vehicle.
