Research Abstract

In this study, we developed a HEMS for a photovoltaic generation system with a lithium-ion battery. First, we analized past 30 years of solar radiations, and examined reliability of the photovoltaic system. We determined daily power supply and battery capacity so that the number of insufficient supply days is 10 a year. We executed experiments for two years; the number of insufficient days was 7 for the first year, and was 2 for the second year. Further, we measured capacity fading characteristics of the battery. The battery could iterate charging and discharging for about 750 times. We modeled the battery, and showed that the capacity fading proceeds according to the amount of charge in the charging and discharging process.
