A REVIEW ON END¿¿?OF¿¿?LIFE BATTERY MANAGEMENT: CHALLENGES, MODELING, AND SOLUTION METHODS

End???of???life (EOL) battery packs may have significant residual value for secondary use and are too expensive to simply recycle. Quality variation adds complexity to EOL decision???making among multiple EOL options including disposal, recycling, remanufacturing, and reuse in secondary applications. The aim of the modeling and analysis for battery???remanufacturing systems is to determine the battery's optimal EOL decisions that maximize cost savings or minimize life cycle cost. This chapter considers the quality variation of EOL returns, resulting in different EOL decisions as well as different routes of remanufacturing processes and inventory level. It discusses some of the basics of battery remanufacturing, including the economic and ecological benefits, principles, operational strategy, and processes of battery remanufacturing. Several emerging issues of battery remanufacturing have been discussed with a main focus on modeling and analysis of electric vehicles (EVs) battery???remanufacturing system as well as decision???making related to the remanufacturing processes, inventory control, and reassembly strategy.
