1. An electrified vehicle comprising:
an inverter configured to convert a DC voltage of an input terminal into an AC voltage based on a pulse width modulation control signal to output the AC voltage to an output terminal;
an inverter controller configured to control a duty ratio of the pulse width modulation control signal in order to adjust a level of the AC voltage to a level of a target voltage based on the target voltage; and
a battery controller configured to:
determine whether an overcurrent is generated based on a maximum instantaneous current output from the output terminal of the inverter in a battery power output mode and terminate the battery power output mode when the overcurrent is generated;
determine whether to re-enter the battery power output mode based on a number of overcurrent generations when the battery power output mode is terminated;
set the level of the target voltage in response to the number of overcurrent generations and re-enter the battery power output mode when it is determined that the number of overcurrent generations is smaller than a preset number of times; and
end the battery power output mode when it is determined that the number of overcurrent generations is equal to the preset number of times.
