  • Abstract:
  • The lithium-ion batteries are specially designed for high power and high energy applications. Battery packs consists of lithium-ion cells connected in series. Lithium-ion cells are not identical due to manufacturing process and environmental factors. Cell unbalancing is the most common reason behind the working failure of battery packs at their possible maximum efficiency. In order to make theses battery packs more efficient and reliable for applications, it is necessary to balance them more frequently. The battery pack management system (BMS) is comprises of cell balancing techniques. This article presents methods to execute algorithm based on theory that continuously monitor state of charge (SOC), cell terminal voltage and available power. This article reviews algorithm for passive cell balancing using switched shunt resistor method.
