The invention relates to the technical field of light commercial vehicles, in particular to a dual-motor series-parallel light truck hybrid power assembly and a working method thereof.The dual-motor series-parallel light truck hybrid power assembly comprises an engine, a clutch, a clutch connecting shaft, a gear shifting mechanism, a main transmission shaft, a mechanical bridge, a first transmission gear set, a first motor, a second transmission gear set, a second motor and a power battery; the engine is connected with the clutch connecting shaft through the clutch; the clutch connecting shaft is connected with one end of the main transmission shaft through the gear shifting mechanism, and the other end of the main transmission shaft is connected with the mechanical bridge. The two motors are fixedly connected with the main transmission shaft and the clutch connecting shaft through the corresponding transmission gear sets respectively. The gear shifting mechanism is provided with two gears; the first motor is electrically connected with the second motor; and the first motor and the second motor are electrically connected with the power battery. The invention provides a series-parallel hybrid power assembly system which can ensure that the load and the fuel saving rate of a light truck are improved and can cover the full use scene of the light truck at the same time.
