Abstract The performance of a battery energy storage system is highly affected by cell imbalance. Capacity degradation of an individual cell which leads to non-utilization for the available capacity of a BESS is the main drawback of cell imbalance. Cell imbalance is common due to internal and/or external sources such as manufacturing deviations, self-discharge rate variation and discharging the cells in an unequal number of cycles. Accordingly, several cell balancing topologies have been proposed by the researchers in the last decade. This paper presents a review of the proposed cell balancing topologies for BESSs. Comparison among the topologies is performed for four categories: balancing speed, charge/discharge capability, main elements required to balance n cell, and application types.
