| 20090033296 | DEVICE, METHOD, AND SYSTEM FOR IMPROVING ELECTRICAL POWER FACTOR AND HARMONIC POWER QUALITY THROUGH ACTIVE CONTROL OF POWER QUALITY IMPROVING ELECTRICAL APPLIANCES - A system, method and device for controlling and modifying the current drawn by an electrical load in a way that will improve the electrical power factor and harmonic quality of at least a portion of an electrical power system. In one embodiment of the invention, the invention includes a controller device that monitors the electrical current entering a site and modifies or corrects power quality of the current by directing how power will be consumed by the appliances at a site to improve the harmonic and power factor qualities of the electrical current entering the site. | 02-05-2009 |
| 20100253290 | Method and apparatus for smart battery charging - A method for managing the charging and discharging of batteries wherein at least one battery is connected to a battery charger, the battery charger is connected to a power supply. A plurality of controllers in communication with one and another are provided, each of the controllers monitoring a subset of input variables. A set of charging constraints may then generated for each controller as a function of the subset of input variables. A set of objectives for each controller may also be generated. A preferred charge rate for each controller is generated as a function of either the set of objectives, the charging constraints, or both, using an algorithm that accounts for each of the preferred charge rates for each of the controllers and/or that does not violate any of the charging constraints. A current flow between the battery and the battery charger is then provided at the actual charge rate. | 10-07-2010 |
