PROBLEM TO BE SOLVED: To provide a regenerative braking control device of an electric vehicle, which can have means for consuming regenerative energy more reliably, and can prevent the shortage of a regenerative braking force as much as possible.SOLUTION: A regenerative braking control device includes: a motor generator 6 for driving a wheel 6T by electric power of a battery 5; and an inverter 6v which drives the motor generator 6 and causes the motor generator 6 to generate electric power using the rotational energy of the wheel 6T, and performs regenerative braking. The regenerative braking control device further includes; a refrigeration cycle device 10 for compressing a coolant by the electric power of the battery 5, and causing a heat exchanger 10c to be heated; a heating cycle device 11 which is heated by the heat exchanger 10c, and through which a medium for heating the battery 5 flows; and a control device 2 which includes power consumption control means causing the refrigeration cycle device 10 and the heating cycle device 11 to forcibly consume the electric power of the battery 5 when the battery 5 is in a fully charged state in which the battery 5 cannot be charged with regenerative electric power of the motor generator 6.
