<p><P>PROBLEM TO BE SOLVED: To charge a user who has actually used a plug socket with electricity charges. <P>SOLUTION: In an electricity charge adjustment system 1, a plug socket 2 is connected with the power supply plug of equipment P1 and P2 or an adaptor 3 and is used not only by the owner of the plug socket 2 but also by the others. The adaptor 3 includes a power supply plug connected to the plug socket 2 and an exclusive plug socket to which equipment P3 is connected, so that the plug socket 2 can be used by the others, and a power received from the plug socket 2 is supplied to the equipment 3. A watt hour meter 4 measures a power or electric energy to be supplied to each plug socket 2. A management server 5 stores the contact information of the adaptor 3, and calculates the electricity charges of the whole plug socket 2 on the basis of power/electric energy data from the watt hour meter 4, and calculates the electricity charges of the adaptor 3 on the basis of the charging source information and contract information from the adaptor 3, and defines charges calculated by subtracting the charges for the adaptor 3 from the whole plug socket 2 as charges with which the owner of the plug socket 2 is charged, and defines the charges for the adaptor 3 as the charges with which the user of adaptor 3 is charged. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
