For ease of understanding, the same components in the following embodiments are used. The same symbol is used to indicate. Referring to Fig. 1 in June, it is a block diagram of an embodiment of the battery grouping system of the present invention. As shown, the battery cluster system of the present invention includes an electrical module 10 and a processing module. The power module contains a plurality of batteries. The processing module 11 is electrically connected to the power module 10, which may be an arithmetic integrated circuit and a processing integrated circuit ’ or an integrated application integrated circuit; and the present invention is not limited thereto. The processing module " can assign a plurality of performance factors affecting the plurality of batteries to different weight values, for example, output power (p〇wer Efficiency) 1U, volume 112, voltage value, and current value (
