In this paper, a rapid cell voltage balancing scheme is proposed for the supercapacitor based energy storage systems in urban rail vehicles.
- •
An improved push–pull converter based balancing circuit is designed to supply high equalization currents.
- •
A cell voltage balancing algorithm based on predictive control theory is proposed to improve the equalization performance.
- •
Both simulation and experiment results are provided to verify the effectiveness of the proposed scheme.
