Device to be Charged with Multiple Charging Channels, Charging Method, and Charging Control Circuit with Multiple Charging Channels

A charging control circuit, comprising:

• a conversion circuit, coupled with a power supply device and a device to be charged, the device to be charged comprising a plurality of cells coupled in series and a system, the conversion circuit being configured to:
• receive input voltage from a power supply device;
• convert the input voltage into charging voltage for the plurality of cells and into power supply voltage for the system of the device to be charged;
• charge the plurality of cells according to the charging voltage;
• and
• supply power to the system of the device to be charged according to the power supply voltage;
• a first charging channel, in which the conversion circuit is disposed;
• a second charging channel, through which the input voltage and input current are received from the power supply device and applied to the plurality of cells to charge the plurality of cells;
• and
• a communication control circuit, configured to communicate with the power supply device to control at least one of the input voltage and the input current received from the power supply device to be able to be applied in a present charging stage of the plurality of cells, when the plurality of cells are charged through the second charging channel.
