MANAGEMENT DEVICE AND MANAGEMENT METHOD

An electric power amount calculation unit calculates, based on a travel route of a work vehicle at a work site and generated electric power from a fuel cell, a required electric power amount of a battery for traveling on the travel route. An instruction unit instructs, in a case where the remaining capacity of the battery falls below the required electric power amount, the work vehicle to stand by until the remaining capacity of the battery is charged to be equal to or more than the required electric power amount by the generated electric power of the fuel cell.
