The present invention relates to a regenerative brake system for an electric vehicle capable of continuous regenerative braking, which is able to perform the subsidiary recollection of power at an off-time of a switching device and allow the regenerative braking to be conducted all the time. According to the present invention, the regenerative brake system for an electric vehicle comprises: an electric motor (M); a battery (B) connected to the electric motor (M); a first switching device (Q1) connected to the part between the electric motor (M) and the battery (B); a second switching device (Q2) connected to the part between the first switching device (Q1) and the electric motor (M); an inductor (L) connected to the part between the second switching device (Q2) and the electric motor (M); a usual regenerative braking unit (A) connected to the inductor (L); and a controller (C) connected to all the devices and controlling the devices.
