Strategy for Active Power Sharing in a Fuel-Cell-Powered Charging Station for Advanced Technology Batteries

Abstract

This paper presents a novel real-time strategy for active power sharing in a fuel-cell-powered charging station for advanced technology batteries. This control scheme can adjust the charging currents according to the estimated state-of-charge which is obtained by estimating the battery open-circuit voltage with current correction and linearly fitting between the open-circuit voltage and the state-of-charge. Both DC and pulse current charging strategies are investigated to coordinate the active power distribution among batteries. The DC charging controller is designed and implemented in MATLAB/Simulink for both system simulation and experimental tests. Simulation and experimental results are also given.
