[0031] This embodiment provides a new energy storage container and a mobile energy storage vehicle, which are stable, reliable and highly safe. The specific scheme is described by the following embodiments.

[0032] The mobile energy storage vehicle of this embodiment includes a vehicle body and an energy storage container. The vehicle body includes a vehicle head and a vehicle frame, and the energy storage container is arranged on the vehicle frame. Since the energy storage container is arranged on the vehicle frame, it means that the bottom of the energy storage container is at a greater distance from the ground.

[0033] See also Figure 1 and Figure 2 The energy storage container of this embodiment includes a box body 1 and a partition wall 2.

[0034] Preferably, the size of the box body 1 is the size of a standard container, which has high versatility, can better meet transportation requirements, and is adaptable to a variety of transportation tools.

[0035] The box body 1 includes a top wall 11, a bottom wall (not shown), side walls 12 arranged on both sides, and end walls 13 arranged at both ends. The top wall 11, the bottom wall, the side walls 12 and the end walls 13 together enclose a storage space that can accommodate a variety of equipment. The partition wall 2 divides the storage space in the box body into multiple compartments.

[0036] Specifically, the compartment includes a battery compartment 14, a first equipment compartment 15, a second equipment compartment 16, and a third equipment compartment 17. The first equipment compartment 15 is arranged away from the front of the vehicle. That is, the first equipment compartment 15 is arranged at one end of the box body away from the front of the vehicle. The second equipment compartment 16 and the third equipment compartment 17 are arranged at the other end of the box body. In other words, the second equipment compartment 16 and the third equipment compartment 17 are close to the front of the vehicle.

[0037] The remaining space in the box body 1, that is, the middle part of the box body, is the battery compartment 14. A plurality of battery packs (not shown) are arranged in the battery compartment 14. It can be understood that the battery compartment 14 is located in the middle part of the box body, which can effectively prevent the battery packs from being damaged by external collisions with the box body during the movement of the vehicle body.

[0038] In some embodiments of the present application, the battery compartment 14 is at least partially covered with an insulation layer (not shown) to effectively isolate the influence of the external ambient temperature and keep the temperature in the battery compartment 14 relatively stable, which is beneficial to improve the safety of the battery pack and extend the life of the battery. In addition, the insulation layer also has a flame retardant effect. When an accident such as thermal runaway occurs in the battery compartment 14, the insulation layer can delay the spread of the fire.

[0039] It should be noted that the surroundings of the battery compartment 14 refer to the surrounding side walls of the battery compartment 14. Specifically, the surrounding side walls refer to the partition walls 2, side walls, top walls and bottom walls that enclose the battery compartment 14. In some examples, the surrounding side walls of the battery compartment 14 are coated with a thermal insulation layer, and the thermal insulation layer is disposed on the side of the surrounding side walls close to the battery pack. In some other embodiments, the thermal insulation layer can also be disposed around the battery compartment 14, that is, on the partition walls 2 and side walls that enclose the battery compartment 14.

[0043] The vent 151 is connected to the heat dissipation port so as to discharge the heat generated by the operation of the converter 3 and the charger 4 out of the box in time.

[0044] A transformer 5 and a control cabinet 6 are also provided in the first equipment compartment 15. The transformer 5 is electrically connected to the converter 3 and the charger 4. The control cabinet 6 is electrically connected to the converter 3. At least one of the transformer 5 and the converter 3 is also provided with a heat dissipation port connected to the vent 151. It can be understood that the user can choose to set a heat dissipation port on the transformer 5, the control cabinet 6, or the transformer 5 and the control cabinet 6 according to actual needs. This embodiment takes the case where both the transformer 5 and the control cabinet 6 are provided with heat dissipation ports as an example, so as to discharge the heat generated by the operation of the transformer 5 and the control cabinet 6 out of the box in a timely manner.

[0045] In some examples, the vents 151 are provided on the side wall of the first equipment compartment. The number of vents 151 may correspond to the number of heat dissipation ports. In other words, in this embodiment, the converter 3, the charger 4, the transformer 5 and the control cabinet 6 are all provided with heat dissipation ports, that is, there are four heat dissipation ports, and correspondingly, there are also four vents 151.

[0046] The heat dissipation port is connected to the vent 151 through a heat dissipation duct structure. The heat dissipation duct structure is hollow inside, one end is connected to the heat dissipation port on the device, and the other end is connected to the vent 151. It can be understood that the shape of the heat dissipation duct structure can be set according to the positional relationship between the heat dissipation port and the vent 151. For example, the heat dissipation duct structure can be L-shaped or linear, as long as the heat dissipation port and the vent 151 can be connected.

[0047] In some examples, the vent 151 is disposed near the top of the first equipment compartment 15 to facilitate heat dissipation.
