Abstract

A hybrid electric vehicle according to one aspect of the present disclosure includes an internal combustion engine, a generator, a battery, an external power supply connector, and a control device. The control device starts charging of the battery by driving the internal combustion engine to cause the generator to generate the electricity, in accordance with the remaining amount of energy of the battery having reached a lower limit amount. The control device ends the charging of the battery by stopping the driving of the internal combustion engine, in accordance with the remaining amount of the energy of the battery having reached an upper limit amount that is set. The control device is configured to modify the upper limit amount by determining the value of the upper limit amount and setting the upper limit amount to the value that is determined.
