Design of Solar Powered Battery Charger: An Experimental Verification

Abstract

This paper presents the design and implementation details of the embedded system to design a photovoltaic based battery charger for lead-acid battery. The battery is charged in float charging mode as well as in bulk charging mode. In bulk charging mode perturb and observe maximum power point tracking algorithm is used to charge the battery. Hardware realization of the PV based battery charger has been carried out and is tested in real time scenario.
