Abstract

   The pre requisite for success of electrical mobility is driven by development of battery technologies. Reliable performance of electrical mobility necessitates for high energy density battery packs. The advent of Li ion cell chemistry revolutionised the electric and hybrid vehicle advancement due to its high energy density, lighter weight and wide range of temperature performance. Higher operating voltages of the battery are achieved by configuration of the cells in series and parallel combinations. The performance of these battery packs are affected by operating temperature and imperfections in manufacturability which causes mismatches in cell impedance, cell potential and state of charge (SOC) imbalance. These performance issues are overcome by cell and battery balancing techniques. In this paper, a dynamic battery pack balancing circuit by using multi inductor with SOC based logic controller for both cell and battery balancing are presented. The battery pack balancing performances during static, charging, discharging conditions are analysed.
