As a new type of energy of large-capacity and high-power, li-ion power battery is widely used in many fields such as energy storage, uninterruptible power system, mobile communications, electric toys, etc. At present, traditional human-based detection methods are mainly adopted in the detection process of battery formation, which to some extent exerts pressure on the cost of human resources and management of lithium battery enterprise. In order to solve this problem, this paper puts forward an elevator scheme applied to formation detection line. The elevator is used to control the battery pack’s movement in the vertical direction and the horizontal direction. The scheme reduces the labor intensity of detection work in the production line. The elevator system has been applied to formation detection lines now, and achieved good economic benefits.

The Way

Li-ion power battery which has a broad prospect of application in many industry fields is a new type of high power battery. The formation-testing and sorting-packing are necessary processes in battery manufacture. Currently the process of formation almost takes the way of monomer battery, then sorting and packing by measuring the parameters of its internal resistance, voltage and capacity. The operation is complicated and the amount of data is huge. On account of the problem, we propose a new process of battery modularization. It can greatly reduce the workload of the parameter testing when using the optimized process. And batteries can get a good consistency, which is favor of sorting-packing and production automation.

Li-ion power battery which has a broad prospect of application in many industry fields is a new type of high power battery. The formation is a key process in battery manufacture. After formation, the active materials of anode and cathode in the battery can be activated. Consequently, the charge-discharge performance, self-discharge performance, reserve performance and some other comprehensive performances can be improved. Only after formation can batteries achieve the best performance. With the change of formation process, the formation and holding for a single battery has been changed to for a group. Therefor, a new type of battery parameter testing equipment needs to be designed, which can test a group of batteries automatically. This paper will introduce the design of this equipment thoroughly.
