Abstract
Charge equalization is important to reduce the damage and improve the lifetime of the battery. An improved control strategy of the equalization circuit is presented in this paper. The over-equalization technique has been utilized to shorten the equalization time about 25%. The hysteresis control is also been used to improve the robustness of the system. The simulation and prototype experimental results have proved the validity and reliability of the proposed control strategy.
