A manufacturing method of a battery module. Firstly, at least two identical electrode metal plates including a frame portion and a metal extending portion are formed by punching. Then, a frame is provided to cover the electrode metal plate to form the integrated battery core frame, and the frame includes the exposed portions to expose the frame portion and the metal extending portion. Thereafter, the electrode connection portion of the metal extending portion is removed. Then, the conductive wire or the chip fuse is arranged on the frame portion of the electrode metal plate for touching the electrode of the battery core and the electrode extending portion of the metal extending portion. Thereafter, a plurality of battery cores and the integrated battery core frame are assembled to have the first electrode and the second electrode of the battery cores touching the electrode touching portions. Finally, the electrode touching portion is connected to the first electrode by welding. |
