Abstract
A battery charge/discharge control device () includes an input-enabled power adjustment unit () having an input-enabled current value calculation unit () and an input power limit value calculation unit (). The input-enabled current value calculation unit () uses a battery current value, a battery temperature value, and an estimated charge capacity value at the time 't' upon execution of detection, so as to obtain an input-enabled current value reduction amount per unit time during charge and an enabled current amount recovery amount per unit time when being left uncontrolled. Moreover, the input-enabled current value calculation unit () calculates an input-enabled current value I(t) to a battery () according to the previously calculated input-enabled current value I(t−1) which has been calculated previously or the only initially set input-enabled current value The input power limit value calculation unit () calculates the battery input power limit value so that the input current limit target value obtained in accordance with the input-enabled current value I(t) is greater than an actual battery current value. Thus, the input-enabled power to the battery () is adjusted in accordance with the battery input power limit value.
