Title:
ELECTRICITY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/056634
Kind Code:
A1
Abstract:
Provided is a technique relating to an electricity storage system that makes it possible to minimize any decrease in the life of a storage battery by reducing loss through suitable control of an operation such as peak cutting. The electricity storage system performs: a process in which the value of a settable item for controlling a peak cutting operation is set by a user; a process for measuring status values including power received from a power system, load power from a load facility, and the voltage, current, and temperature of the storage battery; a process for calculating the SOC value using the measurement value; and a process for controlling charging and discharging of a plurality of storage batteries, including controlling peak cut operation, using the SOC value and the setting values. During peak cut operation, the electricity storage system discharges the storage battery when the load power is at a first load power or more, and charges the storage power when the load power is at a second load power or less, so that the load power is kept within the range from the first load power to the second load power.
