In a method of controlling charging by a motor to improving fuel efficiency of a hybrid vehicle, at least one of turning-on of an engine, turning-off thereof, engagement of an engine clutch, disengagement thereof, performing of charging by P0 and P1 motors, and non-performing of charging by the P0 and P1 motors are selectively combined. In addition to regenerative braking energy recovered by the third motor, regenerative braking energy is recovered by a P0 motor, P1 motor, and a combination of the P0 and P1 motors according to a level of deceleration of the hybrid vehicle that varies with braking power and braking time, and an energy storage system is charged with the recovered regenerative braking energy. Control of charging by each of the P2, P0, and P1 motors is optimized as variable control on a per-deceleration level basis that varies with a level of a power required for braking.
