A hybrid vehicle, comprising: a rechargeable power storage device; an electric motor receiving electric power from said power storage device and generating vehicle driving force; an internal combustion engine; a controller controlling switching of running mode including a first mode in which said internal combustion engine is stopped and running using said electric motor only is given priority, and a second mode in which said internal combustion engine is operated to maintain state of charge of said power storage device at a prescribed target; a running mode switching request switch configured to allow a user to request switching of said running mode; characterized in that the hybrid vehicle further comprises a detecting device for detecting temperature of said power storage device; wherein when switching from said first mode to said second mode is requested by said running mode switching request switch, if a state quantity representing said state of charge is larger than a first specified value and the temperature of said power storage device is lower than a specified temperature, said controller switches said running mode from said first mode to said second mode and sets a second specified value smaller than said first specified value as a target of said state of charge; and when switching from said first mode to said second mode is requested by said running mode switching request switch, if a tolerable charging power (Win) representing electric power that can be input to said power storage device is smaller than a specified value, said controller maintains said first running mode as said running mode. a rechargeable power storage device; an electric motor receiving electric power from said power storage device and generating vehicle driving force; an internal combustion engine; a controller controlling switching of running mode including a first mode in which said internal combustion engine is stopped and running using said electric motor only is given priority, and a second mode in which said internal combustion engine is operated to maintain state of charge of said power storage device at a prescribed target; a running mode switching request switch configured to allow a user to request switching of said running mode; characterized in that the hybrid vehicle further comprises a detecting device for detecting temperature of said power storage device; wherein when switching from said first mode to said second mode is requested by said running mode switching request switch, if a state quantity representing said state of charge is larger than a first specified value and the temperature of said power storage device is lower than a specified temperature, said controller switches said running mode from said first mode to said second mode and sets a second specified value smaller than said first specified value as a target of said state of charge; and when switching from said first mode to said second mode is requested by said running mode switching request switch, if a tolerable charging power (Win) representing electric power that can be input to said power storage device is smaller than a specified value, said controller maintains said first running mode as said running mode.
