Abstract

There is provided a charge/discharge scheduling system in which a measurer measures temperature of a battery unit, a current/voltage measurer measures a voltage and a current at the battery unit, an estimating unit estimates an internal resistance of the battery unit, a scheduler creates, based on a charge/discharge instruction specifying charge amount or discharge amount, a charging schedule or a discharging schedule for the battery unit, a temperature estimating unit estimates time-transition of temperature of the battery unit, based on the internal resistance of the battery unit, the load estimator estimates a load amount applied to the battery unit based on the temperature time-transition of the battery unit provided that the charging schedule or the discharging schedule is carried out, the charge/discharge scheduler creates the charge schedule or the discharge schedule so that the load amount applied to the battery unit is a minimum or smaller than a threshold value.
