Technology
Sony developed an
electrical outlet that manages power consumption for each user and for each electric
appliance. The company applied its Felica technology, a noncontact IC
technology used in the ticket gate of railway stations, to the new electrical
outlet. The IC chip incorporated in a power plug trades data with an electric
outlet to manage power consumption. The system can confirm what appliance
consumes how much power and control the power consumption of each appliance.
The company
developed two types for this authentification electrical outlet. One allows for
wireless information trading between the plug and the outlet, and the other
trades information via electric power line. A server manages the information
traded between appliance and electric outlet intensively via a network. This system will make it possible to supply power to medical devices and
refrigerators on a priority basis when power is in short supply. In addition, a
car owner can pay for charging fee even if he has his car charged by his friend
or acquaintance because the system can tell the power consumption of each
user.
