Technical Field

[0001] This utility model relates to an energy storage battery pack assembly structure and belongs to the field of energy storage battery technology. Background Technology

[0002] To improve battery utilization efficiency, multiple batteries are typically combined into battery modules. A housing structure is frequently used in the process of assembling batteries into modules, neatly stacking the individual batteries inside. Over years of use, battery modules develop various problems, requiring maintenance and replacement of damaged battery cells. However, current battery pack assembly structures are inconvenient to disassemble and reassemble, making maintenance and battery cell replacement difficult. Utility Model Content

[0003] The purpose of this utility model is to solve the technical problems of inconvenient disassembly, assembly, and maintenance in the existing technology, and to provide an energy storage battery pack assembly structure.

[0004] This utility model is achieved through the following technical solution:

[0005] This refers to an energy storage battery pack assembly structure, including a housing. Several layers of lithium batteries arranged in a row are installed inside the housing. Each lithium battery in the housing has a battery fixing block installed at both ends. The battery fixing block has a slot and a protrusion. Adjacent battery fixing blocks are connected by the slot and the protrusion. Several layers of lithium batteries in the same row are arranged in a U-shaped groove. The outer end of the battery fixing block has a slot. The slot has a plug plate installed in the slot. One end of the plug plate has a connecting wire. The plug plate on the negative electrode side of the lithium battery in the same vertical plane is connected to a negative electrode wire through multiple connecting wires. The plug plate on the positive electrode side of the lithium battery in the same vertical plane is connected to a positive electrode wire through multiple connecting wires. The ends of all negative electrode wires are connected to a negative electrode plug together. The ends of all positive electrode wires are connected to a positive electrode plug together.

[0006] When disassembling and repairing this utility model, first disconnect the negative plug and positive wire, then take out each U-shaped slot plate, i.e., rows of lithium batteries, for inspection. When a damaged lithium battery needs to be replaced, simply pull out the plug plate and remove the corresponding battery fixing block, which facilitates the inspection and replacement of the lithium battery.

[0007] Further preferably, corner plates are fixed at both ends of the bottom of the shell, which facilitates the installation of this utility model in different environments.

[0008] Further optimization involves providing an auxiliary lifting rod at each end of the U-shaped channel plate. During maintenance, the U-shaped channel plate can be lifted by holding the auxiliary lifting rod, making maintenance more convenient.

[0009] Further optimization reveals that the battery fixing blocks include both single and double blocks, with the single and double blocks being connected at intervals in the horizontal direction.
