Therefore, cold air can be accelerated to enter the battery module 28 and/or hot air can be accelerated to enter the air cooling system 24, and the heat dissipation efficiency is improved.

Specifically, in one embodiment, two exhaust fans 36 are installed on one battery module 28, one exhaust fan 36 is located at the rear end inside the battery module 28, the other exhaust fan 36 is located at the front end outside the battery module 28, when the exhaust fan 36 at the rear end works, cold air outside the battery module 28 can be sucked into the battery module 28 in an accelerated manner, when the exhaust fan 36 at the front end works, hot air inside the battery module 28 can be sucked out in an accelerated manner and sent to the outside of the front end of the battery cluster 16, the hot air inlet 32 of the air cooling system 24 can be located at the front end of the battery cluster 16, hot air with a relatively high flow rate is formed through the exhaust fan 36, the hot air can enter the air cooling system 24 through the hot air inlet 32 to be cooled, cold air is formed to enter the air inlet duct assembly 22, and the heat dissipation efficiency of the battery cluster 16 is improved. In other embodiments, a single exhaust fan may be mounted to one battery module 28, either at the front or rear end of the battery module 28.

In one embodiment, a suction fan 36 is mounted to the front side of each battery module 28. In one embodiment, several battery modules 28 may share a single suction fan 36. And is not particularly limited herein.

In some embodiments, referring to fig. 1, the energy storage device 100 further includes a chassis 94, and the tank 12 is disposed on the chassis 94. In this manner, installation and handling of the energy storage device 100 may be facilitated.

Specifically, the chassis 94 may be provided with two insertion holes 96 for insertion of a transportation device, such as a fork arm of a forklift, so that the energy storage device 100 can be transported to a target position by the forklift, which facilitates installation and transportation of the energy storage device 100.

In some embodiments, referring to fig. 2, the front panel 99 of the air cooling system 24 is provided with heat dissipation holes 98. In this manner, heat dissipation from the air-cooled system 24 is facilitated.

Specifically, referring to fig. 7, the air cooling system 24 includes a housing, the housing includes a front plate 99 and a rear plate 54, the front plate 99 is provided with a plurality of heat dissipation holes 98, and the rear plate 54 is provided with a cool air outlet 42 and a hot air inlet 32. A plurality of louvers 98 are arranged in an array. The heat generated by the air cooling system 24 during operation can be dissipated outwards through the heat dissipation holes 98, which is convenient for heat dissipation of the air cooling system 24.

In one embodiment, the heat dissipation holes 98 may be disposed to correspond to a heat dissipation fan inside the air cooling system 24.
