Abstract: The present application discloses a winding method and a winding system, and relates to the technical field of battery fabrication. The winding method includes: obtaining a first parameter and a second parameter of each electrode assembly on a winding needle in real time, the first parameter being any one of a number of winding layers, a sheet length and a winding roll diameter, and the second parameter being one or both of the remaining two of the number of winding layers, the sheet length and the winding roll diameter; comparing the second parameters respectively with corresponding preset parameter ranges, the preset parameter ranges being the ranges of the second parameters corresponding to the first parameters of preset standard models corresponding to the electrode assemblies; and adjusting, in response to the second parameter exceeding the corresponding preset parameter range, sheets to be wound of the corresponding electrode assembly.

Abstract: Provided are a winding device and a winding apparatus. An inner shaft of the winding device is configured to clamp an electrode assembly; and an outer shaft of the winding device is configured to wind the electrode assembly. The winding device includes: a first slider and a first pusher, where the first slider may reciprocate in a first sliding slot in the first pusher in a first direction, and an extension direction of the first sliding slot is inclined from the first direction such that the first pusher drives a first inner shaft to reciprocate in a second direction, the second direction being perpendicular to the first direction; and a second slider and a second pusher, where the second slider may reciprocate in a second sliding slot in the second pusher in a third direction, and an extension direction of the second sliding slot is inclined from the third direction.
