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.

在这项研究中，我们开发了一种用于带有锂离子电池的光伏发电系统的 HEMS。首先，我们分析了过去30年的太阳辐射，并检查了光伏系统的可靠性。我们确定了每天的供电量和电池容量，使得每年供电不足的天数为10天。 我们进行了两年的实验；第一年不足天数为7天，第二年不足天数为2天。 此外，我们测量了电池的容量衰减特性。该电池可重复充放电约750次。 我们对电池进行了建模，并表明容量衰减是根据充电和放电过程中的充电量进行的。
