The invention relates to a multi-mode hybrid power system with series-parallel connection and input and output power dividing modes. The multi-mode hybrid power system comprises a first power source, a second power source, a third power source, a planetary gear mechanism, a fixed gear train, a first clutch, a second clutch and a synchronizer. A parallel hybrid power driving mode (a single-motor parallel hybrid power driving mode and a double-motor parallel hybrid power driving mode), a series hybrid power driving mode (a range extending mode), an input power split hybrid power driving mode and an output power split hybrid power driving mode are achieved through a planetary gear mechanism, two clutches and a synchronizer. Compared with an existing multi-mode hybrid power system, the multi-mode hybrid power system has the advantages of being high in system efficiency within the range of all working conditions, simple in structure, easy in spatial arrangement, high in reliability, high in reliability and the like, and can be widely applied to the fields of electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles, electric vehicles and the like. And the working reliability is high.
