When SOC of each power storage device decreases to an SOC control target, the running mode transitions from a CD mode of running with stored electric energy with an engine stopped to a CS mode of running while maintaining stored electric energy by power generation of the engine. An ECU determines a usage pattern of the power storage devices in the CS mode and the CD mode at startup of the power supply system following the start of vehicle driving. Further, in accordance with the determined usage pattern, the ECU appropriately sets an individual SOC target for each power storage device such that, upon ensuring stored electric energy available at the start of the CS mode, stored electric energy to be used in the CD mode is maximized."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Power supply system for electrically powered vehicle and method for controlling the same","description":"A power supply system for a hybrid vehicle includes a main power storage device and a plurality of sub power storage devices used selectively.
