ABSTRACT:
In cases of subjecting an electric motor operated vehicle to electric braking, regenerative braking is performed during the first stage of the braking operation thereby supplying the armature current to the battery as a load, and a plugging operation is performed during the last stage thereof to complete the braking operation, whereby the efficiency of operation is enhanced by conserving the armature current to extend the traveling distance of the vehicle per charge of the vehicle battery, and the generation of excessive heat in the motor is suppressed.
