Conclusion In order to improve the total efficiency of battery packs, an active energy balancing system for Lithium-ion battery pack has been proposed combined with online SOC and SOH estimation. The activation of the cell balancing through the dual active bridge DC/DC converter is controlled by the command from the BMS.
Especially since overcharged lithium-ion cells are dangerous and can burst into flames. A prototype was created to test the circuit design of the system. Hardware components from linear technologies were used because they provided two chips for battery management. The system monitors six blocks connected in series.
