Problems solved by technology
[0002] At present, soft-pack batteries are generally sorted manually. For each battery, it is necessary to use a multimeter to measure the voltage and internal resistance, and manually record the voltage and internal resistance data, and then query the corresponding capacity and K value data of the battery through the database. Manually determine the gear to which the battery cell belongs, the workload is heavy and the work efficiency is low, and it is easy to make mistakes

The invention provides a soft package cell sorting method. The method comprises the following steps that a grading parameter is set; a bar code on the surface of a cell to be tested is scanned througha code scanning gun so as to obtain initial data of the cell to be tested; the positive and negative electrodes of the cell to be tested are connected through a fixing device; Detecting by a tester is carried out to obtain test data of the cell to be tested; a test K value is calculated according to the initial data and the test data; and whether the initial data, the test data and the test K value of the cell to be tested meet the grading parameter or not is judged, if so, that the cell to be tested is a qualified product is judged and the gear position of the cell to be tested is determined, and otherwise, that the cell is an unqualified product is judged. The invention further provides a soft package cell sorting device. According to the soft package cell sorting device and the method,the grading parameter is preset, and automatic testing and grading judgment are carried out on the cell to be tested, so that precision and the accuracy of the sorting process are improved, and testing efficiency is improved.
Description
【Technical field】 [0001] The invention belongs to the technical field of battery sorting, and in particular relates to a soft-pack battery sorting device and method. 【Background technique】 [0002] At present, soft-pack batteries are generally sorted manually. For each battery, it is necessary to use a multimeter to measure the voltage and internal resistance, and manually record the voltage and internal resistance data, and then query the corresponding capacity and K value data of the battery through the database. Manually determine the gear to which the battery cell belongs, the workload is heavy and the work efficiency is low, and it is easy to make mistakes. In view of this, it is necessary to provide a pouch cell sorting device and method to overcome the above-mentioned defects. 【Content of invention】 [0003] The invention proposes a sorting device and method for soft-packed battery cells, which can automatically sort and test the battery cells and improve the sorti...
