Keywords:
battery management system, pack-to-multicells, series-parallel structure, switched capacitor, voltage equalizationAbstract
Voltage unbalance is one problem on series-connected battery pack. Different circuit strategies has been developed to overcome the issue by presenting dissipative or nondissipative mechanisms to achieve state of charge equalization of the battery. The presented strategy in this paper uses a special series-parallel structure of switched capacitor with the modification of additional equilibrium voltage setpoint adjustment. The proposed design is able to push the final averaged voltage (3.79 V) higher than conventiional series-parallel structure (3.70 V).
