1. A method of controlling a flying object that includes a generator, which includes a solar cell, and an energy storage apparatus, the method comprising, during flying of the flying object, the steps of:
in a first mode, determining when a voltage of an energy storage device in the energy storage apparatus reaches a lower limit voltage of a voltage range in which charge and discharge of electricity can be reversibly repeated; and
in a second mode, when a time until the energy storage device is recharged is a predetermined time or more, at least one of maintaining or decreasing altitude of the flying object while making the energy storage device discharge electricity within a voltage range lower than the lower limit voltage,
wherein, in a voltage range lower than the lower limit voltage, the method further comprises dissolving of lithium ions from a negative electrode in an electrolyte solution and transferring of the lithium ions to a positive electrode.
