The invention discloses a composite braking system of an electric vehicle, which comprises a composite braking system body, an automobile electric driving assembly is arranged on the composite braking system body, a motor assembly is arranged on the automobile electric driving assembly, and an electromagnetic braking mechanism and a pneumatic braking mechanism are arranged on rotating shafts at the two ends of the motor assembly. A copper coil is arranged on an iron brake disc body, close to the edge, of an inner brake disc on the electromagnetic brake mechanism, an electromagnetic coil is arranged on the inner side of an outer electromagnetic brake chuck outside the inner brake disc, and an outer electromagnetic brake chuck connector lug is arranged on the outer side wall of the outer electromagnetic brake chuck. An air bag braking groove is formed in the position, close to the edge, of the interior of an internal braking disc of the pneumatic brake, an external braking disc is arranged on the periphery of the exterior of the internal braking disc, and a braking air bag on the inner side of the external braking disc is installed in cooperation with the air bag braking groove. According to the composite braking system, magnesium generated by electricity is adopted for realizing homopolar repulsion and braking. The pneumatic brake mechanism achieves braking of an internal brake disc through inflation and bulging of a brake air bag.
