In order to be suitable for load terminals (communication equipment) with different rated powers and/or meet different power-reserve duration requirements, a corresponding number of battery cabinets can be selected to be connected in parallel. That is, when the rated power of the load end is small and/or the demand of the standby time is small, only a small amount of even one battery cabinet 10 can be used for supplying power; when the rated power of the load end is larger and/or the demand of the standby time is larger, the output power is improved by connecting a plurality of battery cabinets in parallel, and the requirement of the rated power is met.

The parallel connection between the battery cabinets can be realized through a parallel connection connector 17, and then the electric energy is output through an output connector 18. It should be understood that the output power can be directly output to the communication device, or input to the rectifying device of the power cabinet 26, and then output to the communication device after rectification.
