The invention discloses an electrically driven power transmission device which comprises a shell, a drive motor, a planet row gear mechanism, a first friction operation device and a second friction operation device, the planet row gear mechanism comprises a first sun gear, a second sun gear, a planet carrier, a first planet gear and a second planet gear, and the first planet gear and the second planet gear are arranged on the planet carrier. The first planetary gear is meshed with the first sun gear, the second planetary gear is meshed with the second sun gear, and the first friction running device is arranged to be used for braking the first sun gear; the second friction operation device is arranged to be used for controlling the first sun gear and the second sun gear to rotate synchronously so that the whole planet row gear mechanism can rotate. According to the electrically-driven power transmission device, power output can be kept through mutual cooperation of the two friction operation devices in the gear shifting process, and power interruption in the gear shifting process is avoided; and a planetary mechanism composed of the cylindrical outer gears is adopted, machining and manufacturing are convenient, and the product development difficulty is lowered.
