In this application, an air distribution channel 3 is installed on the side of the energy storage bin where the air inlet window 11 is installed, and the air distribution channel 3 is located on the air inlet side of the battery PACK. After the battery PACK is installed inside the energy storage bin, the air can be transported from the air inlet window 11 to the air outlet window 12 through the fan on the battery PACK, and the air in the bottom control bin can be sucked into the energy storage bin through the air distribution channel 3, so that the air inside the control bin can be circulated. The installation of the fan 42 inside the control bin is reduced, and the processing cost and energy consumption during use are reduced.

[0027] Specifically, in this embodiment, there is a spaced arrangement between one side edge of the partition 2 close to the air inlet window 11 and the inner wall of the cabinet body 1, and the air diversion channel 3 is located at the gap between the partition 2 and the inner wall of the cabinet body 1.

[0028] Specifically, in this embodiment, the air diversion channel 3 is located on the side of the air inlet window 11 away from the air outlet window 12.

[0029] Specifically, in this embodiment, when the fan on the battery PACK is in the working state, air flows from inside the control bin and the air inlet window 11 into the inside of the air diversion channel 3 respectively, and then is transported by the air diversion channel 3 into the inside of the battery PACK. After heat exchange and cooling of the inside of the battery PACK, it is discharged through the air outlet window 12.
