The invention belongs to the field of wind energy utilization, and discloses an approaching airstream energy recovery device of an electric automobile. The device comprises a generator, a wind energy concentration device and a wind turbine, wherein the wind energy concentration device is a pipeline of which an inlet and an outlet in the two ends are wide and the middle is narrow, and is arranged in a front cabin of the automobile; the inlet is positioned in the rear side of an air inlet grille of the automobile; the outlet is formed in the bottom of the front cabin of the automobile; the wind turbine is arranged in the wind energy concentration device; the generator and the wind turbine are connected through a permanent magnetic bearing; the tail ends of the wind turbine and the generator are connected with rolling bearings respectively; the wind turbine is formed by combining lift genre blades and resistance genre blades, so the starting performance and the actual operation performance of the wind turbine are improved; during the running of the electric automobile, an airstream which enters the front cabin of the automobile from the air inlet grille is firstly introduced into the wind energy concentration device, and flow field optimization is performed through rectification and speed-up effects of the concentration device; the optimized airstream flows to the blades of the wind turbine to drive the wind turbine to rotate, and the generator starts to work under driving of the wind turbine, so that the conversion of wind energy to electric energy is realized.
