Abstract: A charging system includes n first charging modules, a first switch matrix, a second switch matrix, and m first output apparatuses. Each first charging module includes a plurality of first power converters, each first power converter has one output bus, the output bus of the first power converter is connected to the first switch matrix. The first switch matrix is configured to connect or disconnect output buses of any two of the plurality of first power converters. The first output apparatus j is connected to a corresponding first charging module by using the second switch matrix. The second switch matrix is configured to transmit, to the first output apparatus j, electric energy on an output bus of a first power converter in any first charging module corresponding to the first output apparatus j.

Abstract: A charging system may include a plurality of power modules, a distributing switch module, and a plurality of charging ports. The distributing switch module includes a first distributing unit and a second distributing unit. The first distributing unit may connect a first part of power modules in the plurality of power modules to a first charging port, to distribute powers of the first part of power modules to the first charging port. The second distributing unit may connect a second part of power modules in the plurality of power modules to a second charging port, to distribute powers of the second part of power modules to the second charging port. Therefore, the first charging port may charge a first terminal, and the second charging port may charge a second terminal.
