A converter is connected to a selected one of the plurality of sub power storage devices to perform voltage conversion bidirectionally between the selected sub power storage device and an electric power feeding line. A control device executes a disconnection process to disconnect a selected sub power storage device from the converter based on a state of charge of the selected sub power storage device when there is no new sub power storage device that can replace the selected sub power storage device. Further, the control device executes a braking process for the inverter for regenerative braking by the motor. The control device prohibits, during execution of one process of a disconnection process and braking process, the other process."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electric powered vehicle and control method for the same","description":"An electric powered vehicle includes a motor, an inverter, a main power storage device, and a plurality of sub power storage devices.
