The invention discloses a battery cell winding method and equipment. According to the method, a positive pole piece and a negative pole piece are heated before winding, so the stress of the pole pieces is sufficiently released, the pole pieces are lengthened to a certain degree under the tensile action during winding, after the winding is finished, the pole pieces contract along with an isolation film in the cooling process, and the deformation of the battery cell is accordingly improved. The equipment comprises a machine frame, a motor arranged in the machine frame, a positive pole piece feeding mechanism, a negative pole piece feeding mechanism, an isolation film feeding mechanism and a winding mechanism which are fixedly connected with the machine frame respectively, wherein the machine frame is also connected with a positive pole piece heating mechanism and a negative pole piece heating mechanism. The beneficial effects of the technical scheme are as follows: the method is simple and practical, and can be applicable to automation continuous production; and the equipment is simple to operate, the heating mechanisms are easy, and the large-scale manufacturing is facilitated.
