Title:
STORAGE BATTERY CHARGE/DISCHARGE CONTROL DEVICE AND STORAGE BATTERY CHARGE/DISCHARGE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2014/167928
Kind Code:
A1
Abstract:
By determining the charge/discharge current value on the basis of the amount of time for charging and discharging and the battery state of the storage battery, directing the initiation of charging and discharging of the storage battery by using the PV power generated in a photovoltaic power generation (PV) system, the load power consumed by a load, and the storage battery output calculated by multiplying the storage battery voltage and the charge/discharge current value, and charging and discharging the storage battery at a calculated constant current, it is possible to obtain a storage battery charge/discharge control device and a storage battery charge/discharge control method which are capable of suppressing sudden increases and instant changes in the charge/discharge current value of the storage battery, even in cases in which PV power fluctuations and load power fluctuations occur suddenly, and which achieve degradation prevention and a longer operating life for the storage battery.
