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.

Abstract: A charging method, a charging apparatus, and a charging system are described. The charging method includes a first control module enabling a first link based on target charging power of a first to-be-charged apparatus and charging power of a first charging apparatus. The first to-be-charged apparatus waits for being charged on a first charging parking space. The first control module corresponds to the first charging apparatus. The first control module enables the first link and charges the first to-be-charged apparatus at a first shared charging power. The first shared charging power includes real-time charging power of at least one first charging apparatus and at least one second charging apparatus.

Abstract: A charging cabinet includes a power conversion circuit, an input interface, and a plurality of output interfaces. An input end of the power conversion circuit is connected to the input interface. The power conversion circuit converts an alternating current supplied by an alternating current power grid into a direct current, and then charges a plurality of battery packs by using the direct current.
