The invention discloses an extended-range hybrid power system for a longitudinal rear-drive vehicle, and provides a longitudinal rear-drive extended-range hybrid power line configuration scheme, the extended-range hybrid power system comprises a range extender composed of an engine and a generator, a coaxial electric drive rear axle, a power supply distribution box, a motor controller and other parts, specifically, the generator is coaxially and directly connected with the generator, and the generator is coaxially and directly connected with the generator. The generator and the engine form dynamic coupling, and electric energy generated by the generator can be transmitted to the coaxial electric drive axle through the motor controller; the power supply distribution box is respectively connected with the power battery and the motor controller; the coaxial electric drive axle comprises a motor and a differential mechanism, and the motor and the differential mechanism are coaxially arranged. Through reasonable system design and layout, the complexity of a common hybrid power system is optimized, the number, the weight and the occupied space of parts are reduced, the comprehensive cost is greatly reduced, and meanwhile the arrangement requirements of plug-in and non-plug-in type range extending hybrid power longitudinal rear-drive vehicles can be met.
