Control design and testing of a novel fuel-cell-powered battery-charging station

This paper presents a novel system design for a fuel-cell-powered battery-charging station. This battery charging station allows multiple batteries to be charged simultaneously. Three baseline static charging algorithms are proposed to coordinate the power distribution among the battery branches. The control strategies include equal rate charging, proportional rate charging and pulse current charging. These charging algorithms are then realized in MATLAB/Simulink, and the current and voltage regulations are implemented using the classical proportional-integral approach. The system simulation is conducted in VTB by embedding Simulink objects and cosimulating with MATLAB. The experimental tests are performed by compiling Simulink codes and downloading onto the DSpace platform. The simulation and experimental results are also given.
