Abstract: Provided are a battery winding method, a battery winding system, a battery and an electrical device. The battery winding method includes: winding; photographing a picture of a current winding layer; acquiring position data of a first point and of a second point according to the picture of the current winding layer, converting the position data of the first point to obtain the converted position data of a converted first point using a preset conversion matrix corresponding to the current winding layer based on the number of the current winding layers and calculating data of displacement between the first and second electrode plates based on the converted position data of the converted first point and the position data of the second point, and determining if the data of displacement is within a threshold value scope, if so, returning to wind a next winding layer, and if not, sending an alarm.
