Micro-Controller Unit Application in Fuzzy Battery Equalization Control for Battery String

An intelligent battery equalization scheme is presented, based on and accordingly designed as fuzzy logic controlled battery equalization controller (FLC-BEC). It can effectively reduce equalization time. The proposed individual cell equalization (ICE) scheme is a bidirectional dc-dc converter, based on the Cuk converter operated at discontinuous inductor current mode (DICM). A state space approach is adopted to inspect the stability of the proposed FLC-BEC. Matlab/Simulink simulation and experimental results can be used to verify the stability of FLC-BEC. In this article, an 8-bit micro-controller unit (MCU) is used to accomplish the FLC-BEC, which can reduce volume and complexity of the hardware used for the FLC-BEC.
