Electric power supplier, method for controlling supplying of electric power, and information processing device

A method for controlling supplying of electric power, comprising

• sending electric power to a first load from a power circuit via a first path;
• sending electric power to a second load, comprising a secondary battery, from said power circuit via a second path connected to the first path;
• detecting a signal from a second load which indicates that the battery is fully charged;
• disconnecting said second load according said signal;
• detecting a value of the electric power sent from said power circuit to the first and second loads;
• and
• electrically connecting and disconnecting a node between the first and second paths to or from the second load, based on a detected value of the electric power.

An information processing device comprising:

• electric power supplier having an alternating/direct-current conversion circuit which converts an alternating voltage into a direct voltage, and outputs a converted voltage;
• a first path, one end of which is connected to said alternating/direct-current conversion circuit, and other end of which is connected to a first load, said first path supplying output voltage of said alternating/direct-current conversion circuit to said first load;
• a second path, one end of which is connected to said first path, and another end of which is connected to a second load, comprising a battery circuit including a secondary battery, wherein said battery circuit detects whether the secondary battery is fully charged with electricity, and sends a detection signal which represents detection results to a current control circuit and said current control circuit generates a control signal for electrically disconnecting the node from said second load,
• a switch circuit which is formed in said second path;
• and
• a current detection circuit which detects a value of a current flowing through a portion of said first path between said alternating/direct current conversion circuit and a node between said first path and said second path, and controls said switch circuit to electrically connect or disconnect the node to or from said second load, based on a detected current value;
• and
• an information processing unit which is connected to said electric power supplier and driven by a voltage, applied thereto and sent from said electric power supplier;
• and
• wherein said information processing unit includes
• a memory which stores information,
• an operational input section which inputs an instruction,
• an input/output control section which performs inputting and outputting processing,
• a display section which displays information, and
• a processor which supervises a state of said operational input section through said input/output control section, reads out information from said memory and/or an external memory, executes processing based on read information, and controls said display section to display information corresponding to executed processing.
