摘要

For the balancing circuit based on three-resonant-state LC unit, the energy transfer between cells cannot be carried out in the self-resonant state, which reduces the balancing speed. To overcome this problem, this paper proposes a voltage balancing circuit based on LC unit with dual LC resonant tanks. The proposed balancing circuit is composed of a LC unit with dual LC resonant tanks and a switch network. By alternately connecting two LC resonant tanks with imbalanced cells, each state of the proposed balancing circuit can transfer energy between cells, which improves the balancing speed. Meanwhile, the zero-current switching (ZCS) of the switch is implemented. Simulation results are provided to verify the validity of the proposed balancing circuit. The results show that the proposed balancing circuit has higher balancing speed than the balancing circuits with three-resonant-state LC unit.
