[0002] The battery box of the energy storage system is installed on the battery rack in the cabinet or battery compartment. Each battery rack arranges several battery boxes in the height direction. Only the front of the battery rack can be assembled. Therefore, the battery box must be pushed into the battery rack and fixed from the front of the cabinet or battery compartment. With the development of electrochemical energy storage systems towards large capacity, the number of cells in a single energy storage battery box has increased from 16 to 104 cells, and the weight of a single battery box has also increased from about 100KG to about 650KG, far exceeding the capacity of manual handling and loading and unloading. Each energy storage system is assembled from several to hundreds of battery boxes, so the assembly workload is huge. Now, special loading and unloading equipment or forklifts are usually used for battery box transportation. However, although the special loading and unloading equipment has a high degree of automation, it is expensive and requires a large investment. Although the forklift transportation has a small investment, it is restricted by the battery rack structure. The forklift can only transport the battery box to the front of the corresponding installation position of the battery rack, but cannot push the battery box into the battery rack. The assembly of the battery box must be completed with the help of manual or other forces, which poses a great safety hazard.
