HYBRID VEHICLE AND OUTPUT CONTROL METHOD FOR ELECTRIC POWER STORAGE DEVICE INSTALLED THEREIN

When electric power exceeding output allowable power at an engine startup time is output from a power storage device, deviated from a predetermined period of time (T1) during which the output allowable power of the power storage device is switched, an ECU suppresses increase of the output allowable power for the next startup time of the engine. Specifically, the ECU modifies the output allowable power for the next startup time of the engine from a first value (WoutE (1)) to a second value (WoutE (2)) lower than the first value, based on a period of time (T2) before deviation is eliminated.
