This application provides a reduction gearbox (100), an electric vehicle drive system, and an electric vehicle. The reduction gearbox (100) includes a motor input shaft (1a), an engine input shaft (1b), an intermediate shaft (2), a first output shaft (3a), a second output shaft (3b), and a differential gear (4), where the first output shaft (3a) and the second output shaft (3b) are in transmission connection with the differential gear (4); and further includes: a first transmission assembly (XI), configured to connect power transmission between the motor input shaft (1a) and the intermediate shaft (2); a second transmission assembly (X2), configured to connect or disconnect power transmission between the engine input shaft (1a) and the intermediate shaft (2); and a third transmission assembly (X3), configured to connect or disconnect power transmission between the intermediate shaft (2) and the differential gear (4). The reduction gearbox provided in this application can resolve a problem that an engine and a generator in an existing series extended range electric vehicle cannot directly drive a vehicle, thereby improving acceleration performance, economy, and maneuverability of the vehicle.
