Abstract

The demand for battery modules for vehicle driving is increasing rapidly. However, many battery modules are not economically viable because they are either discarded or chemically recycled for use as stationary batteries. In this research, we analyze the residual performance of rechargeable batteries to determine the reuse suitability and propose a cluster analysis technique to minimize performance degradation owing to performance variation. The system constructed from the research is expected to demonstrate its value in supportings the utilization of limited resources economically because it directly intervenes in preventing and responding to problems that occur because of the performance error in the reuse of secondary batteries.
