Abstract
In one embodiment, electrical appliances in a household are connected to a power supply through power limiters that are further coupled to a controller. The power limiters include power sensors. Abnormal power consumption situations are detected by the power sensors. A communication unit coupled to the controller is triggered to communicate the abnormal situations to a personal computing and communication device of in a communication network. A user may send instructions to the controller to change operation modes of the appliances. In another embodiment, subsystems of an electrical appliance are connected to a power supply through power limiters.
Claims20
A power management system comprising:
- (a) a power source;
- (b) a plurality of electrical appliances, wherein each of the appliances is connected to the power source through a power limiter, wherein said power limiter further comprising a power sensor;
- (c) a communication unit;
- (d) a controller that is coupled to the power limiters and to the communication unit;
- and
- (e) a means of detecting and communicating an abnormal power consumption status of anyone of said appliances.
A power management system for an electrical appliance comprising:
- (a) a plurality of subsystems, wherein each of the subsystems is connected to a power source through a power limiter;
- (b) a communication unit;
- (c) a controller pertaining to controlling at least operations of the power limiters and the communication unit;
- and
- (d) a means of detecting and communicating an abnormal power consumption status from anyone of said subsystems.
A method of power management for an electrical system comprising a plurality of subsystems, the method comprising:
- (a) connecting each of the subsystems to a power supply through a power limiter;
- (b) setting power limit of the power limiters by a controller;
- (c) detecting an event that power consumption of anyone of the subsystems reaches the power limit;
- and
- (d) communicating the event to an external computing and communication device through a communication link.
