Problems solved by technology

However, the research object of the existing sorting method is the battery cell. In actual engineering, the battery cell is connected by welding or riveting after being connected in series or in parallel. The sorting method that takes the battery cell as the research object needs to disassemble the battery module. The battery level takes a lot of time

Abstract

The invention discloses a rapid sorting method and device for battery modules. The method comprises the steps of obtaining n groups of detection signals, which are respectively measured at n detectionend points, of n battery modules connected in series under the single-energy pulse excitation; recovering a source signal of each battery module according to the obtained detection signals; and sorting the n battery modules based on a classification result of the source signals. According to the rapid sorting method for the battery modules provided by the invention, rapid sorting of the battery modules can be realized based on the rapid charging process, and the battery sorting efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of battery modules, in particular to a method and device for rapid sorting of battery modules. Background technique [0002] In the next five to ten years, a large number of electric vehicles will be decommissioned. The decommissioned batteries still have 70% to 80% of their remaining capacity and life, and are widely used in cascade utilization energy storage equipment. Due to the differences in the working conditions and manufacturing processes of decommissioned power batteries, the consistency and aging degree of decommissioned power batteries show obvious differences. sexual issues. Therefore, the consistency screening of batteries must be carried out before cascade utilization to improve the energy utilization and safety of cascade utilization batteries. [0003] Traditional decommissioned battery sorting methods generally use standard capacity testing to obtain battery capacity, electrochemical imped...
