Disclosed are a mixed battery group and battery grouping method. The mixed battery group forms a battery via a serial connection between a primary power supply battery and an auxiliary power supply battery, wherein a unit voltage rated capacity of the auxiliary power supply battery is higher than that of the primary power supply battery. The mixed battery group provides an entire voltage output of a battery set to supply power externally, and also provides one or more auxiliary power supply sets having a voltage lower than the voltage of the battery to supply power externally. |
