A regenerative braking control device for an electric vehicle comprising: a shaft resistor connected in parallel to the motor circuit via a diode; A command is issued to the mode switching contactor to make a connection to maintain the regeneration mode when the voltage is lower than the motor generated voltage, and a connection is made to the mode switching contactor to convert from the regeneration mode to the plugging mode when the battery voltage is higher than the motor generated voltage. 1. A regenerative braking control device for an electric vehicle, comprising a control means for generating a command to be performed by a switching contactor.

(2) A utility model registration claim characterized in that the voltage comparison by the detection means is performed using a forward voltage drop of a freewheeling diode connected between the direction switching contactor and the DC power supply. The regenerative braking control device for electric vehicles according to item (1).
