The invention relates to a coaxially-arranged extended-range hybrid power system. The system comprises an engine, a power generator coaxially arranged with the engine, an input assembly, a battery, adriving motor and an output assembly, wherein the input assembly and the battery are connected with the power generator, the driving motor is connected with the battery and coaxially arranged with thepower generator, and the output assembly is connected with the driving motor. The input assembly is further connected with the engine and has at least five working modes including a range extending driving mode, a pure electric driving mode, a parking charging mode, an engine starting mode and an energy recovery mode. According to the coaxially-arranged extended-range hybrid power system, the power generator, the driving motor and a gear pair are integrated in a synthesis box, the integration degree is high, and matching installation is facilitated; a parallel shaft type two-stage speed reducing mechanism is used, and the structure is simple and reliable; the engine is coupled with the power generator to realize a range-extending power generation function; the engine is decoupled from thedriving system, the engine stably works at an efficient power point, higher fuel economy is obtained, and the use cost of a vehicle is reduced.
