1. A power generation control device for an electric vehicle, comprising:

  • a power generator driven by an internal combustion engine;

    a drive battery capable of storing power generated by the power generator and sensing an SOC that is a state of charge; and

    a drive motor capable of propelling a vehicle using power generated by the power generator or power stored in the drive battery,wherein the power generation control device sets in advance an SOC target value that is a convergence target of the SOC of the drive battery, and controls a power generation torque of the power generator to correspond to an output that is a sum of a drive request output calculated based on a manipulation separately from a drive torque of the drive motor and a battery request output calculated based on a deviation between the SOC of the drive battery and the SOC target value.
