When the external stacker carries the tray 26 filled with batteries to the lifting frame 22, the staff can control the two cylinders 231 on the left and right to rise through the button, thereby driving the lifting frame 22 and the tray 26 to move upward. When the tray 26 is lifted into place, the thermistor module 242 and the positive and negative probe modules 241 will contact the batteries in the tray 26, so that the positive and negative poles of the battery are pressed with the positive and negative probe modules 241 respectively, and the probes in the positive and negative probe modules 241 can pierce the surface oxide layer of the battery tabs to achieve a good contact effect; the thermistor module 242 contacts the shell part of the battery, and can monitor the battery temperature in real time; after the pressing is completed, the power module 13 performs the capacity division process.

When the battery capacity separation process is completed, the lifting frame 22 descends, and the integrated machine returns to the initial state where the tray 26 enters the equipment. At the same time, the integrated machine will feedback a signal to the stacking system, and the stacking system will transfer the separated tray 26 to the next process, thereby completing the entire battery capacity separation process.
