1. A vehicle comprising:
an electrical load;
a generator;
a battery; and
a controller configured to:
control an operation of the generator based on a charging rate of the battery;
identify, based on a duty ratio of an input voltage applied to the generator, a power generation margin representing a ratio of a power that the generator is operable to output to a maximum power;
reduce power consumption of the electrical load based on a comparison between the power generation margin and a target margin; and
set the target margin based on a sum of a first target margin based on the charging rate of the battery, a second target margin based on a driving state of the vehicle, a third target margin based on a type of the electrical load, and a fourth target margin based on the duty ratio of the input voltage.
