Problems solved by technology

[0003] However, most of the detection processes in the existing detection devices require manual operation, which is inefficient and not suitable for mass production and use. In addition, the detection probe cannot accurately measure the battery due to the fact that the battery is not positioned and fixed during the detection process. In addition, the existing detection device did not classify the batteries in time after the test, which also caused unnecessary trouble for the subsequent battery classification

Abstract

The invention belongs to the technical field of lithium batteries, and particularly relates to a lithium battery charging and discharging detection system and a detection technology.The lithium battery charging and discharging detection system comprises a workbench, a conveying belt is arranged at the top of the workbench, a lithium battery is placed at the top of the conveying belt, and the top of the lithium battery is fixedly connected with a positive and negative electrode connector; supporting plates are fixedly connected to the two sides of the workbench, and the sides, close to each other, of the two supporting plates are fixedly connected with the same placement plate. The lithium battery charging and discharging detection device is simple in structure and convenient to operate, manual operation is not needed in the charging and discharging detection process of a lithium battery, the detection process is full-automatic, the detection efficiency is greatly improved, and the detection cost is reduced. And the lithium batteries are positioned and fixed before detection, so that the situation that the positive and negative electrode connectors are misplaced with the charging and discharging detection head and the charging connector and cannot be accurately detected is prevented, and in addition, the detected lithium batteries can be classified in time.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a lithium battery charge and discharge detection system and detection process. Background technique [0002] While the output of lithium-ion batteries continues to expand, its high-capacity ultra-thin technology development, quality inspection and quality tracking have also attracted more and more attention from the industry. The application of lithium-ion batteries largely depends on the stability of its charge-discharge cycle, and like other secondary batteries, it is inevitable that the capacity of lithium-ion batteries will decrease after repeated charge-discharge cycles. There are many reasons for capacity fading, including material and manufacturing process factors. Therefore, the detection of lithium batteries is very important. [0003] However, most of the detection processes in the existing detection devices require manual operation, which is inefficient and...
