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 includes one or more direct current-to-direct current conversion modules, a first power sharing bus, a second power sharing bus, at least one first output end, and at least one second output end. The direct current-to-direct current conversion module includes at least one first energy supply unit and at least one second energy supply unit. The first energy supply unit is coupled to the first power sharing bus. The second energy supply unit is coupled to the first power sharing bus and the second power sharing bus. The first output end is coupled to the first power sharing bus. The second output end is coupled to the second power sharing bus. A maximum output power of the first output end is different from a maximum output power of the second output end.

Abstract: In this application, a calendar day may be divided into a plurality of time periods. When a terminal that newly enters prepares to be charged in a first charging area in a plurality of charging areas in a first time period in a plurality of time periods and the charging station does not have an allocable power in the first time period, a charging power of each terminal in the charging station may be reallocated based on an actually used power of the first charging area in the first time period and a preset power allocation ratio of the plurality of charging areas.
