Abstract


Battery packs with flexible connection have drawn growing attention currently as an efficient dynamically reconfigured design solving drawbacks emerged in battery management and cell balancing, enhancing circuit real time reliability and fault tolerance ability. Studies among cell reconfigurable topologies and simulations are carried out in order to reveal the regulations of related topology formation, with existing and proposed topology schemes analyzed for circuit optimization and SOC equalization. A maximum decline of 25% in the number of electronic switches utilization for the same quantity of the batteries is found possible for topologies generated from the proposed method.
