A method of charging a battery by a charging system comprising a master charging circuit and N (N is a natural number) slave charging circuits. The method includes: sourcing a first current to a single-wired bus by the master charging circuit; absorbing (sinking) a second current from the single-wired bus by the N slave charging circuits connected to the single-wired bus; identifying a single-wired bus voltage formed on the single-wired bus at a particular time point by the master charging circuit; and identifying the number of slave charging circuits based on the single-wired bus voltage by the master charging circuit.
A charging system for charging a battery through a master charging circuit and N (N is a natural number) slave charging circuits, the master charging circuit and the N slave charging circuits being communication-connected through a single-wired bus, the master charging circuit comprising a single-wired master communication unit configured to supply (source) a first current to the single-wired bus and identify the number of slave charging circuits based on a single-wired bus voltage formed on the single-wired bus in a first mode, and to calculate a maximum charging current of each charging circuit according to the number of slave charging circuits and regulate the single-wired bus voltage according to the maximum charging current in a second mode, and the slave charging circuits comprising single-wired slave communication units configured to absorb (sink) a second current from the single-wired bus in the first mode and to identify the maximum charging current according to the single-wired bus voltage in the second mode.
A master charging circuit for transmitting power received from a Universal Serial Bus (USB) host to N (N is a natural number) slave charging circuits connected in parallel, the master charging circuit comprising:
