A battery managing device includes a first calculator, a second calculator, a determiner, and a controller. The first calculator calculates a provisional value indicating a charge state of a battery provided in a vehicle including an electric motor as a drive source. The second calculator calculates the charge state of the battery based on a condition obtained by comparing the provisional value and a boundary point which is on a boundary between a plurality of regions divided in accordance with an available charged amount of the battery. The boundary point is determined based on the available charged amount of the battery in a predetermined degradation state. The determiner determines in which region among the regions the charge state of the battery locates. The controller controls to charge and discharge the battery in accordance with the region determined by the determiner.

Battery managing device and battery managing method

There is provided a charge controller capable of charging a capacitor while suppressing the progress of deterioration of the capacitor without unnecessary charge/discharge of the capacitor. The charge controller includes a voltage sensorthat detects the voltage of a capacitor, a current sensorthat detects the charge/discharge current of the capacitor, a battery ECUthat estimates the SOC of the capacitorbased on the detected voltage, and a management ECU. The management ECUcalculates the charge/discharge amount from the start of charging of the capacitorby integrating the charge/discharge currents detected by the current sensorand controls the charging of the capacitorbased on the estimated SOC and the calculated charge/discharge amount. The management ECUupdates and sets the estimated SOC to an actual use upper limit SOC based on the state characteristics of the capacitor
