Abstract
Description
Technical Field
[0001] This utility model belongs to the field of battery technology, and in particular relates to a battery pack packaging structure. Background Technology
[0002] With the in-depth development of new energy industries such as energy storage, photovoltaics, and wind power, various new energy sources are integrating to form complementary energy stations. Complementary energy stations generally include wind power-storage power stations, photovoltaic power-storage power stations, and wind-solar-storage power stations.
[0003] With the vigorous development of new energy sources, the current of various new energy products is increasing, and the performance requirements for these products are also becoming more stringent. Due to the considerable weight of battery modules, wooden crates are commonly used for packaging and transportation in the current market. However, this not only increases the volume of packaging materials but also raises transportation costs. While cardboard boxes are also used for packaging and transportation, the weight of battery modules and the lack of internal corner supports in cardboard boxes make them prone to deformation, potentially damaging the battery module structure and causing losses.

[0031] This application, by setting a protective frame, a first gap, and a second gap and controlling their setting method and position, can effectively enhance the packaging strength of the battery module structure and the stacking strength of the battery module, giving the battery module strong impact resistance, while also significantly reducing packaging costs.
[0032] In a preferred embodiment, the first protective frame 20, the second protective frame 30, the third protective frame 40 and the fourth protective frame 50 are all drawer-type protective frames; each drawer-type protective frame has an L-shaped notch A at the end corner near the end face of the battery module 10.
