Description

Technical Field

[0001] The utility model relates to the technical field of containers, and more specifically, to an energy storage box with a battery pack mounting hanger structure. Background Art

[0002] As a special container that carries a large number of battery packs, the energy storage container requires multiple battery packs to be installed inside in advance.

[0003] As shown in the attached figure of the instruction manual Figure 4 and Figure 5 As shown, several groups of flush battery brackets 10 are provided in the energy storage box. The battery bracket 10 includes an end limit plate 60 at the bottom, a frame 61 on the side, a battery pack 62 on the frame, a top limit plate 63 and a structural reinforcement 64 at the bottom of the battery bracket. The battery pack 62 is integrated on a sliding frame and pushed into the interior along the battery bracket 10. The weight of each battery pack 62 is about 500-700kg. The on-site installation must use a special stacker to raise the battery pack 62 to the corresponding position, and then apply an inward thrust through the end face until the battery pack 62 is placed on the battery bracket 10. This method relies too much on stackers and is greatly restricted by on-site factors. At the same time, pushing the battery pack 62 in a sliding manner can easily cause damage to the chassis of the battery pack 62 and the fall off of the anti-corrosion layer of the battery bracket 10. The pushing process can easily cause imbalance on both sides, and then reinstallation is required, and the installation efficiency is very low. Utility Model Content
