Abstract
An ECU controls a PCU to perform capacity recovery control of recovering a capacity of an assembled battery. The capacity recovery control includes a discharge mode and a capacity recovery mode. In the discharge mode, the ECU discharges the assembled battery to a predetermined overdischarge region. In the capacity recovery mode, the ECU repeatedly performs, in the overdischarge region, a voltage increase of increasing a voltage across a lithium ion secondary battery due to a stop of the discharging and a pulse discharge of discharging the lithium ion secondary battery while oscillating a discharge current.
