Systems and methods for an intelligent energy-saving power supply

摘要

The systems and methods described herein include an intelligent energy-saving power supply system which conserves energy by recognizing when a chargeable electronic device, such as a cellular telephone, has been detached from its battery charger and by then cutting off power to the battery charger to prevent energy from being consumed while not serving the useful function of charging the chargeable electronic device. In addition, these systems may optionally include a device which turns off the receiver circuit of an electronic device to additionally save power and an interface which displays the amount of energy conserved by using the energy-saving power supply system.

主权项

1. A power supply system comprising:
an electrical power outlet arranged to removably couple to a battery charger; a sensing device coupled to the electrical power outlet, arranged for sensing an outlet state representative of at least one of a voltage, a current, and a temperature over a period of time of the electrical power outlet; a switch arranged for controlling a coupling between a power source and the electrical power outlet; a processor coupled to the switch and to the sensing device, arranged for:
learning a plurality of outlet states of the electrical power outlet representative of decoupling and coupling of a chargeable electronic device to the battery charger,identifying decoupling of the chargeable electronic device from the battery charger,opening the switch to cut power from the power source to the electrical power outlet,identifying coupling of the chargeable electronic device to the battery charger, andclosing the switch to restore power from the power source to the electrical power outlet; and a web server coupled to the processor, wherein the web server is arranged for:
determining energy saved by the power supply system over a plurality of time periods, andgenerating for display a web page comprising an indication of the energy saved by the power supply system over a plurality of time periods.
