Description

Technical Field

[0002] A battery pack is a modular battery system formed by assembling and connecting multiple battery cells according to certain structural and electrical requirements. It is widely used in electric vehicles, energy storage systems, portable power supplies, drones and other fields. The main function of a battery pack is to provide stable power output and support efficient energy storage and management. The battery pack assembly device is a device used to assemble multiple battery cells according to certain structures and requirements to form a complete battery pack. These battery packs are widely used in new energy electric vehicles, energy storage systems, portable power supplies and other fields. The core function of the battery pack assembly device is to integrate battery cells, battery management systems, protection circuits, cooling systems and other components to ensure the safety, reliability and efficiency of the battery pack.

[0003] Most of the existing battery packs are modules formed by assembling and connecting multiple battery cells according to a certain structure. However, when assembling the battery pack, it is very time-consuming and labor-intensive because multiple lithium batteries need to be arranged and assembled. Manual operation is not only time-consuming but also inefficient, especially when there are a large number of battery cells. The time consumption is obvious, and it is difficult to detect each individual lithium battery after the battery pack is assembled. If the batteries cannot be detected individually, these abnormal batteries will be missed, resulting in improper overall charge and discharge management of the battery pack and damage to the batteries. In view of the above problems, the inventor proposes a battery pack assembly device to solve the above problems. Summary of the invention
