1. An energy system that includes a plurality of storage batteries and an information processor, wherein:
the plurality of storage batteries supply stored electric power to an electric device, each of said storage batteries being individually set to a maximum SOC representing a charging limit and a minimum SOC representing a discharging limit, each of said storage batteries being chargeable and dischargeable under the control of an external device and being capable of measuring SOC values; and the information processor controls charging and discharging processes of said storage batteries individually to keep said storage batteries charged until SOC values acquired from said storage batteries reach said maximum SOC when said storage batteries are charged and to keep said storage batteries discharged until SOC values acquired from said storage batteries reach said minimum SOC when said storage batteries are discharged, wherein said information processor:
individually establishes, for each of said storage batteries, a charging-stop SOC, which serves as an index for stopping the charging process, and which is lower than said maximum SOC, or a charging-stop ratio within a usable SOC range;controls the charging processes of said storage batteries individually to keep said storage batteries charged until SOC values acquired from said storage batteries reach said charging-stop SOC or said charging-stop ratio when said storage batteries are charged; andsaid information processor sets said charging-stop SOC and said charging-stop ratio based on the amounts of electric power consumed in said energy system and based on the instructions for reverse power flow to a power distribution system and charging instructions to said storage batteries. |
