Abstract: The present invention provides a distributed energy storage system, and applications thereof. In an embodiment, the distributed energy storage system includes power units, wherein each power unit has a multi-cell battery; a battery manager that monitors battery cell voltages and temperatures; and a controller. The controller provides a first control signal that causes the power unit to store energy in the battery and a second control signal that causes the power unit to generate an alternating current. A server in communication with each of the power units stores data collected from the power units about the batteries and analyzes the data to determine how much available energy is stored in the batteries that can be used to alter a load demand of a power network, hi an embodiment, the batteries are lithium ion batteries capable of storing at least ten kilowatt- hours of energy.

Abstract: A power shedding device controls the application of power from an uninterruptible power supply (UPS). It includes circuitry for detecting an alarm signal indicative of a condition requiring the rationing of power from the UPS, and a plurality of power outlets for connection to a plurality of loads such as computers, printers, and other associated devices. A microprocessor controls the application of power to each power outlet pursuant to program control such that the application of power to a first power output is independent of the application of power to a second power output. Manually operable switches are provides for presetting shedding profiles for the power outlets during a shutdown procedure. The processor is responsive to receipt of an alarm signal to shed each power output in accordance with its corresponding manually preset shedding profile. A low UPS battery alarm results in an override of the shedding profiles if the remaining time to shutdown for an outlet exceeds a predetermined limit.
