The invention provides a multi-purpose adaptive second-gear multimode stepless speed changing electric transmission integrated power system. The multi-purpose adaptive second-gear multimode stepless speed changing electric transmission integrated power system comprises a first motor and the like; a planetary gear train comprises a gear ring, a planet carrier and a sun gear; the rotor of the first motor is connected with the gear ring of the planetary gear train; the rotor of the second motor is connected with the sun gear of the planetary gear train and the input end of a transmission chain, respectively; a gear shifting device is connected with the input end of a speed reducing differential mechanism and control on power transfer from the planet carrier of the planetary gear train and the output end of the transmission chain to the speed reducing differential mechanism is realized; the output end of the speed reducing differential mechanism is connected with two wheels by use of two half shafts; a motor control device is connected with an energy storage device to transfer electric energy; the motor control device is further connected with the first motor and the second motor, respectively, and outputs control instructions. The multi-purpose adaptive second-gear multimode stepless speed changing electric transmission integrated power system has the characteristics of better technical inheritance to the existing vehicles, whole vehicle dynamic property, fuel economy and low emission.
