The invention belongs to the technical field of electric driving systems, and particularly relates to a double-planet-row electric driving system, a vehicle and a gear shifting method. The electric driving system comprises a gearbox shell, a first motor, a second motor, a first planet row, a second planet row, a connecting device and a system output shaft, the first planet row comprises a first sun gear, a first gear ring and a first planet carrier, and the second planet row comprises a second sun gear, a second gear ring and a second planet carrier; wherein a rotor of the first motor is connected with the second sun gear, and a rotor of the second motor is connected with the first sun gear; the first planet carrier is connected with the second gear ring; the second planet carrier is connected with the first gear ring and the system output shaft. The connecting device is used for fixedly connecting the first planet carrier with the gearbox shell or fixedly connecting the first planet carrier with the first gear ring. By the adoption of the double-planet-row electric drive system, power of the vehicle can not be interrupted in the gear shifting process, and therefore the performance of the electric vehicle is improved.
