The invention discloses a series type pure electric-driven electric automobile. The series type pure electric-driven electric automobile comprises driving shafts distributed in a pairwise mode. Each driving shaft comprises a first driving half shaft and a second driving half shaft which are in transmission connection with each other in sequence, wherein the first driving half shaft and the second driving half shaft are in transmission connection with each other from the center of the electric automobile to one side of the electric automobile in sequence; a disc type motor controller, a disc type motor and a planet reducer are sequentially distributed on the first driving half shaft; the disc type motor controller is connected with the disc type motor and used for controlling the disc type motor; the disc type motor is in transmission connection with the planet reducer, and the planet reducer is rotated through the first driving half shaft and the second driving half shaft; and the tail end of the second driving half shaft is in transmission connection with a wheel of the electric automobile. The center axes of the disc type motors on the driving shafts distributed in the pairwise mode are connected in series. According to the scheme, the problem that the occupied space is large due to the fact that existing electric automobiles adopt traditional radial magnetic flow type motors and step parallel axis reducers can be solved.
