The embodiment of the invention relates to the field of new energy batteries, in particular to a battery cell welding method, a device and electronic equipment. The method comprises the steps of acquiring the number of each welding point in a to-be-welded cell module; obtaining the number of each welding strip in the plurality of welding strips; controlling a conveying piece to carry the to-be-welded cell module to be carried out; finding the number of welding points corresponding to the serial number of the welding strips according to the number of each welding strip when the to-be-welded cell module is transmitted to a welding equipment; controlling the welding equipment to weld the welding strip with the found welding point; judging whether the tensile strength of the welding point to be welded is qualified or not according to a preset tension judgment value, if the tensile strength of the welding point is qualified, then controlling the welding equipment to be separated from the welding strip welded to the welding point. By means of the method, the device and the electronic equipment, the welding efficiency of the cell module can be improved.
