Abstract
A regenerative brake device increases its regenerative brake power during high-speed driving, without impairing driveability. A regenerative brake device includes a driving wheel linked with a rotary shaft of an electric motor through a power transmission system and a battery charging circuit provided between the electric motor and a set of batteries. The battery charging circuit is switched OFF and ON to execute the regenerative braking in response to the duty factor of control pulse signals inputted to the battery charging circuit. The duty factor of control pulse signals inputted to the battery charging circuit decreases as the rotational speed of the rotary shaft of the electric motor increases, thereby increasing the braking power within a range that does not exceed a predetermined braking power.
