Abstract
The aim of this experimental activity is to investigate batteries charging/discharging process and, as a consequence, to quantify batteries roundtrip efficiency value. Experimental trend of voltage, current and power input/output from batteries are observed during charging/discharging operation. Results of the experimental activity show that during the charging process, the voltage from the solar array tapers according to the batteries conditions and recharging needs, thus increasing the charge acceptance of the battery. Once batteries are about to reach full charged condition, the controller starts to hold constant voltage and reduce the charging current to avoid overcharging. Taking advantage of experimental activity results, average value of batteries roundtrip efficiency is determined.
