Abstract: A refrigerating system include a heat management module, a direct cooling module, a plurality of heat exchange modules, and a plurality of cooling pipes. The heat management module may send, to the direct cooling module, control information that indicates that the charging pile needs to charge a terminal device. The direct cooling module may be configured to convert a gas refrigerant transmitted in a second pipe assembly into a liquid refrigerant, and transmit the liquid refrigerant to each heat exchange module and each cooling pipe through the first pipe assembly.

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.

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.
