Abstract:
This paper presents a novel charge equalization technique seamlessly integrated into a modular Battery Management System (BMS) for lithium-ion (Li-ion) batteries. The charge equalizer is a crucial element for an effective use of a Li-ion battery consisting of many series-connected cells. We describe a fully distributed charge equalizer based on a circular balancing bus, which outperforms other recently published approaches. Its safety requirements have formally been verified using a model checker, showing that formal methods and, in particular, the Symbolic Analysis Laboratory environment, can be effective to verify the safety requirements of a BMS.
