ELECTRIC POWER CONTROL DEVICE, MOVING OBJECT, AND ELECTRIC POWER CONTROL METHOD

An electric power control device includes an acquisition unit configured to acquire information indicating a maximum power value that is a maximum value of electric power that can be output from a battery without causing an excessive output voltage drop and information indicating a requested power value, a determination unit configured to determine a suppliable power value indicating electric power that can be supplied from the battery to a starting mechanism when starting a stopped internal combustion engine, based on a difference between a maximum power value and a requested power value, and a control unit configured to start the internal combustion engine using electric power corresponding to the suppliable power value determined by the determination unit.
