The battery pack of the present invention adopts the above-mentioned split-type mounting beam to fix the battery pack without the module structure, and does not need to apply additional pressing force to the battery pack, effectively avoids the problem of the welding quality of the bus bar, and improves the battery pack. The safety of use; through the two locking beams, the two ends of the battery pack are squeezed at the same time, and the battery cells of the battery pack are tightly connected together to ensure the reliability of the battery pack during use;

The assembling method of the battery pack of the present invention uses the above-mentioned split mounting beam, so the assembling method can realize the automatic boxing of the battery pack, and simplifies the assembling process, and the assembled battery pack has the advantages of safe and reliable use .
