1. An electric power supply apparatus that supplies power to an external load, comprising:
a generator configured to generate electric power by motive power of an engine;
a container configured to house a battery;
a first detector configured to detect a remaining amount of the battery housed in the container; and
a processor configured to:
calculate an amount of electric power that can be generated by the generator, on the basis of an actual measurement value of an amount of electric power generated by the generator during a period from present time to a predetermined period ago;
determine a maximum amount of electric power that can be output from the electric power supply apparatus at a present point of time in a case of using both electric power from the generator and electric power from the battery, on the basis of the remaining amount of the battery detected by the first detector and the calculated amount of electric power; and
notify a user of the determined maximum amount of electric power.
