Abstract: A power-driven system includes: a differential; a power output shaft configured to link to a power input end of the differential; multiple input shafts; and a first motor generator. The differential includes a first planet carrier, a second planet carrier, a first planet gear, a second planet gear, a first ring gear, and a second ring gear. The first planet gear and the second planet gear are respectively disposed on the first planet carrier and the second planet carrier and respectively meshed with the first ring gear and the second ring gear. One input shaft of the multiple input shafts is configured to selectively link to the power output shaft, and another input shaft of the multiple input shafts is configured to link to the power output shaft. The first motor generator is configured to link to the one input shaft of the multiple input shafts.
