Optimal battery chargers for photovoltaic system based on fuzzy theory and Taguchi method

Optimal battery chargers for photovoltaic system based on Fuzzy theory and Taguchi method is presented. Applying Fuzzy theory to the battery charging systems, the charge time can be reduced and the charge efficiency can be improved. The Taguchi parameter design method is utilized to optimize the battery charging system for multistage constant current-constant voltage (MCC-CV) technique, and the results of measurement verify the feasibility of this structure in the experiment.
