A method and system for controlling charging of a hybrid vehicle are provided. The method includes generating a request to charge a battery by driving a hybrid starter generator (HSG) with power of an engine in an electric vehicle (EV) mode of the hybrid vehicle. In addition, the method includes decreasing torque of the engine to HSG charging engine torque, maintaining the torque of the engine at the HSG charging engine torque, and shifting torque of the HSG into charging-target HSG torque. A pressure of a clutch disposed between the engine and a driving motor of the vehicle is released to interrupt transference of power from the engine to the driving motor. The battery is then charged with power output from the HSG while the HSG is rotating by driving power output from the engine.

1. A method for controlling charging of a hybrid vehicle, comprising: generating, by a controller, a request to charge a battery by driving a hybrid starter generator (HSG) with power of an engine in an electric vehicle (EV) mode of the hybrid vehicle;decreasing, by the controller, torque of the engine to HSG charging engine torque, maintaining the torque of the engine at the HSG charging engine torque, and shifting torque of the HSG into charging-target HSG torque;releasing, by the controller, a pressure of a clutch disposed between the engine and a driving motor of the vehicle to interrupt transference of power from the engine to the driving motor;charging, by the controller, the battery with power output from the HSG while the HSG is rotating by driving power output from the engine; andconfirming, by the controller, whether the pressure of the clutch has been released, after releasing the pressure the clutch,wherein the generation of a request to charge a battery by driving a hybrid starter generator (HSG) with power of an engine in an electric vehicle (EV) mode of the hybrid vehicle is performed when state-of-charge (SOC) of the battery is lower than a preset value while the hybrid vehicle is traveling the EV mode,wherein the charging the battery with power output from the HSG while the HSG is rotating by driving power output from the engine is performed when the pressure of the clutch has been released, andwherein when the pressure of the clutch has not been released a return is performed to the release the pressure of the clutch to interrupt transference of power from the engine to the driving motor. 2. A system for controlling charging of a hybrid vehicle, comprising: a memory configured to store program instructions; anda processor configured to execute the program instructions, the program instructions when executed configured to:generate a request to charge a battery by driving a hybrid starter generator (HSG) with power of an engine in an electric vehicle (EV) mode of the hybrid vehicle;decrease torque of the engine to HSG charging engine torque, maintain the torque of the engine at the HSG charging engine torque, and shift torque of the HSG into charging-target HSG torque;release a pressure of a clutch disposed between the engine and a driving motor of the vehicle to interrupt transference of power from the engine to the driving motor;charge the battery with power output from the HSG while the HSG is rotating by driving power output from the engine; andconfirm whether the pressure of the clutch has been released, after releasing the pressure the clutch,wherein the generation of a request to charge a battery by driving a hybrid starter generator (HSG) with power of an engine in an electric vehicle (EV) mode of the hybrid vehicle is performed when state-of-charge (SOC) of the battery is lower than a preset value while the hybrid vehicle is traveling the EV mode,wherein the charging the battery with power output from the HSG while the HSG is rotating by driving power output from the engine is performed when the pressure of the clutch has been released, andwherein when the pressure of the clutch has not been released a return is performed to the release the pressure of the clutch to interrupt transference of power from the engine to the driving motor. 3. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising: program instructions that generate a request to charge a battery by driving a hybrid starter generator (HSG) with power of an engine in an electric vehicle (EV) mode of the hybrid vehicle;program instructions that decrease torque of the engine to HSG charging engine torque, maintain the torque of the engine at the HSG charging engine torque, and shift torque of the HSG into charging-target HSG torque;program instructions that release a pressure of a clutch disposed between the engine and a driving motor of the vehicle to interrupt transference of power from the engine to the driving motor;program instructions that charge the battery with power output from the HSG while the HSG is rotating by driving power output from the engine; andprogram instructions that confirm whether the pressure of the clutch has been released, after releasing the pressure the clutch,wherein the generation of a request to charge a battery by driving a hybrid starter generator (HSG) with power of an engine in an electric vehicle (EV) mode of the hybrid vehicle is performed when state-of-charge (SOC) of the battery is lower than a preset value while the hybrid vehicle is traveling the EV mode,wherein the charging the battery with power output from the HSG while the HSG is rotating by driving power output from the engine is performed when the pressure of the clutch has been released, andwherein when the pressure of the clutch has not been released a return is performed to the release the pressure of the clutch to interrupt transference of power from the engine to the driving motor.
