Abstract

As electric vehicles and energy storage systems continue to develop and popularize, how to maximize the working time of batteries has become a major concern. For the sake of facilitating battery management, individual batteries are generally grouped to form battery packs by serial and parallel connections and a complete power supply system consists of those packs either in series or in parallel. However, the inconsistency of performances between different battery packs will seriously aggravates in the usage of batteries, resulting in a sharp reduction on the working time of batteries. In this paper, we propose a novel scheme of redistributing battery packs and design an appropriate system of managing the charging and discharging process of batteries, so that the lifetime of batteries can be greatly extended.
