An improved battery pack equalizer based on a DC/DC converter with fuzzy logic controller

Abstract

This paper presents an improved battery pack equalizer (BPE) based on a DC/DC converter using fuzzy logic controller (FLC). This BPE can be designed without the necessity of a cell model in the pack. It is simple and robust. The simulation results have demonstrated that the BPE with the FLC has better performance than the BPE with the PI controller in terms of the balancing speed and efficiency.
