The invention discloses a battery forming system. The battery forming system comprises a battery conveying line as well as a current collection sheet bending apparatus, a cap press-in apparatus, a first welding apparatus, a battery turnover apparatus, a second welding apparatus and a battery unloading manipulator which are arranged in sequence in a feeding direction of the battery conveying line, wherein a defective battery box is arranged at the tail end of the battery conveying line; a first short circuit detection apparatus is fixedly mounted between the cap pressing-in apparatus and the first welding apparatus; a second short circuit detection apparatus is fixedly mounted between the second welding apparatus and the battery unloading manipulator; a first welding point detection apparatus is mounted on one side, far away from the cap press-in apparatus, of the current collection sheet bending apparatus; and a second welding point detection apparatus is mounted between the second welding apparatus and the second short circuit detection apparatus. According to the battery forming system, the bending of a current collection sheet, the press-in assembly of a cap and a battery, the welding of the battery cap and a bottom cover, and the detection of a battery welding effect and whether a short circuit exists are realized, the battery production efficiency is improved, and the battery performance reliability is ensured.
