In Hoque et.al (Mohammed Mozammel Hoque et al., 2015) proposed a voltage-based equalization technique that exposes individual cell monitoring and quick balancing of cell voltages. The cell balancing circuit was built using two flyback converters to transfer energy between cells during charging and discharging operations.
The validity of the battery equalization is further verified using an experimental installation involving a battery string of three lithium–ion cells.
The DC-DC converter based balancing circuits (used to redistribute the charge among the cells in the battery pack) are the key component in the cell balancing as its conversion efficiency affects the overall performance of the EVs.
