Abstract:
Pulsed current provides a rest-time for battery cells to fully complete internal chemical reactions that can suppress the increase of resistance to extend the battery lifetime. This paper proposes a new method to implement pulsed current using synchronized/unsynchronized Phase-Shift Modulation during both charging and discharging processes in a smart battery management system. Faulty cells can be permanently bypassed without any impact on the architecture of the Smart Battery. Simulation and experimental results verify the feasibility of the proposed method.
