Description

Technical Field

[0001] The utility model relates to the field of battery cell manufacturing, in particular to a sorting machine for new energy battery cells. Background Technique

[0002] The new energy battery pack process mainly consists of processes such as cell detection, sorting, grouping, and assembly. Due to the differences in the production of power batteries, when the lithium battery packs are inconsistent, when a single lithium battery with too high energy encounters an accident, it will cause thermal runaway, and the battery will react sharply inside. In a short time, too much energy has nowhere to be released, which is very dangerous. Especially when the safety technology and control ability are not developed enough, the capacity of each battery should be restricted. The inconsistency of lithium battery parameters mainly refers to the inconsistency of capacity, internal resistance, and open circuit voltage. Even batteries of the same batch will have differences in capacity, internal resistance, etc. Therefore, in order to pursue the purpose of battery consistency, it is necessary to sort them first to exert the maximum capacity of the battery pack (including maximum power, maximum current, and maximum available capacity), and also want to maintain such ability for as long as possible.

[0003] In the existing battery cell sorting device, after being tested by a battery testing device, workers need to manually place the batteries into the corresponding collection boxes, resulting in low work efficiency. Based on this, the utility model proposes a sorting machine for new energy battery cells, which realizes the automatic sorting of battery cells and adjusts different sorting process parameters for different battery cells, greatly improving the sorting efficiency of battery cells.
