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.

Abstract: A battery module is configured to discharge to a terminal device, and the battery module includes: a detection and control unit, a buck-boost unit, and a cell pack. The detection and control unit is configured to: receive a terminal-required voltage sent by the terminal device; and control the buck-boost unit to discharge to the terminal device through the cell pack based on the terminal-required voltage.

Abstract: A vehicle-mounted power supply system includes a sampling circuit, a voltage comparison control circuit, a power conversion circuit, and a motor. The sampling circuit is configured to obtain an output voltage value of an output terminal of the power conversion circuit. The voltage comparison control circuit is configured to output a first power adjustment signal to the power conversion circuit when the output voltage value is less than a first target voltage value. The power conversion circuit is configured to increase an output voltage to a first target voltage based on the first power adjustment signal, to output the output voltage to the motor and increase an input voltage of the motor. When a voltage of a power supply is low, the input voltage of the motor can be maintained at a required level.
