Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, and specifically, to an energy storage battery pack. Background Art

[0002] In scenarios with high power consumption such as outdoor camping, outdoor live streaming, outdoor construction, or location shooting, the on-site conditions are relatively poor, and most lack sufficient power supplies for various devices. Therefore, outdoor power battery packs are widely used. For the battery packs of existing air-cooled energy storage systems, there is at least one fan on the front side of the battery pack, and two rows of air inlets are opened on the rear side. By starting the fan, the fan extracts the internal air, creating a negative pressure inside the battery pack. The air on the rear side enters the battery pack from the air inlets under the action of atmospheric pressure. Inside the battery pack, the air flow is divided into different flow paths through the air ducts and flows over the battery surface to dissipate heat from the battery modules and battery cells.

[0003] Chinese Patent No. CN204424349U provides an energy storage battery pack housing, including at least one battery pack mounting bracket, a top cover, a peripheral shell, and a support frame. One end of the support frame is provided with at least one groove, and the other end of the support frame is provided with at least one air flow feeding device mounting groove, and the groove communicates with the air flow feeding device mounting groove; the battery pack mounting bracket is formed by mating and combining two battery pack mounting bracket components, and the battery pack mounting brackets are placed in layers above the grooves of the support frame. The top cover is arranged on the top of the uppermost battery pack mounting bracket, and an opening with a certain angle is formed between one end of the top cover and the top of the uppermost battery pack mounting bracket. The peripheral shell is installed and fixed around the battery pack mounting bracket. An energy storage battery pack is also provided. Using the energy storage battery pack with the energy storage battery pack housing of the present utility model can reduce the temperature difference between battery packs and extend the service life of the battery pack.

[0004] Although the above patent can solve the heat dissipation problem of the battery to a certain extent, it cannot ensure good uniformity of heat dissipation of the battery packs, and there is no good solution for fixing multiple groups of batteries. Moreover, the auxiliary functions of the battery pack are few, and functions such as viewing the remaining power and selecting connection methods are not available. Summary of the Utility Model
