The invention belongs to the technical field of electric vehicle battery replacement, and particularly relates to an electric vehicle power battery and vehicle body separation device and a control method thereof. A limiting assembly in the device comprises a female head, and a limiting groove is formed in the inner wall of the female head; the fixing and separating assembly is matched with the limiting assembly, so that the power battery is fixed or separated; the fixing and separating assembly comprises a male head, a male head sleeve and balls, the male head sleeve is fixedly arranged on the fixing assembly, through holes capable of containing the balls are formed in the outer wall of the male head sleeve, the male head comprises an inserting part and a limiting part, the radial width of the inserting part is smaller than that of the limiting part, the inserting part is provided with a groove, and abutting faces are symmetrically arranged at the two ends of the limiting part. The male head sleeve is sleeved on the inserting part, and the groove corresponds to the through hole; the power unit provides driving force for the transmission assembly, and the transmission assembly drives the male head to reciprocate under the action of the driving force, so that the balls can be clamped into or separated from the limiting grooves, and fixation and separation between the power battery and the vehicle body are achieved.
