Abstract
In this paper, the author researches on the life prediction and matching test of decommissioned power battery based on energy storage system. The practical background of the research on decommissioning batteries was analysed. The research status and development trend of lithium battery prediction at home and abroad are introduced. The research methods of battery quality prediction technology are introduced, especially the utilization and key technology of decommissioned lithium battery in power system. Through the practical application of various prediction techniques, the overall quality of the decommissioned battery (charge state, internal resistance and material deterioration degree, etc.) is finally determined. Thus, the utilization ratio of lithium power battery is further improved.
