摘要

A discharge share ratio calculation unit (52) calculates, for each power storage device, a remaining electric power quantity before an SOC is reached with respect to which an allowable discharge electric power is restricted, and calculates a discharge power share ratio between power storage devices according to the ratio of the remaining electric power quantity. A charge share ratio calculation unit (54) calculates, for each power storage device, a chargeable quantity before an SOC is reached with respect to which an allowable charge electric power is restricted, and calculates a charge power share ratio between power storage devices according to the ratio of the chargeable quantity. When electric power is supplied from a power supply system to a drive force generation unit, each converter is controlled according to the discharge power share ratio and, when electric power is supplied from the drive force generation unit to the power supply system, each converter is controlled according to the discharge power share ratio.
