POWER SUPPLY DEVICE FOR ELECTRIC POWERED VEHICLE, CONTROL METHOD THEREOF, AND ELECTRIC POWERED VEHICLE
First Claim
1. A power supply device for an electric powered vehicle, comprising:
- a power storage device for storing electric power input/output with respect to an electric motor generating vehicle driving power,a power line connected to an external power supply during external charging,a power converter for executing bidirectional power conversion between AC power of said power line and DC power input to and output from said power storage device,an outlet electrically connected to said power line, anda control device for controlling DC power input to and output from said power storage device by said power converter,said control device configured to execute temperature-rise control, in an event of a temperature of said power storage device being lower than a predetermined temperature when said external power supply is connected to said power line, and said electric load is connected to said outlet, alternately causing a first state where electric power output to said power line from said power converter is controlled such that power consumption of said electric load is ensured in association with discharging of said power storage device, and a second state where electric power input to said power storage device from said power converter is controlled such that power consumption of said electric load is ensured in association with charging of said power storage device.

Abstract
An electric load is electrically connected to a path between an external power supply and a power storage device. An ECU executes temperature-rise control, when the temperature of the power storage device is low, ensuring power consumption of the electric load in association with charging/discharging of the power storage device. During execution of temperature-rise control, the ECU sets a power command value of the external charger, alternately causing a discharging mode having the output power of the external charger positively controlled and in which power consumption of the electric load is ensured in association with discharging of the power storage device, and a charging mode having the output power of the external charger negatively controlled and in which power consumption of the electric load is ensured in association with charging of the power storage device.
