Abstract:
In one embodiment, there is provided a power interchange system for distributing direct current (DC) electrical power. The power interchange system comprises a plurality of nodes comprising a first node and a second node. The first node comprises a first communication device and a first power source to power the first communication device. The second node comprises a second communication device and a second power source to power the second communication device. The power interchange system further comprises a wired cable connecting the first node and the second node. The wired cable comprises at least one first wire to convey DC power from the first power source of the first node to the second node to power the second communication device or from the second power source of the second node to the first node to power the first communication device.
Abstract:
This document relates to electricity management using modulated waveforms. One example modulates electricity to obtain modulated electricity having at least two different alternating current frequencies including a first alternating current frequency and a second alternating current frequency. The example delivers the modulated electrical power having the at least two different alternating current frequencies to multiple different electrical devices, including a first electrical device configured to utilize the first alternating current frequency and a second electrical device configured to utilize the second alternating current frequency. The modulated electricity can be delivered at least partly over an electrical line shared by the first electrical device and the second electrical device.

Abstract:
According to one aspect, embodiments of the invention provide a method of operating a UPS system, the method comprising receiving, at an input of a first UPS, input power from a power source, generating, with a first analysis circuit, a first signal indicative of a characteristic of the input power, receiving, at the analysis circuit, a second signal from a second analysis circuit of a device coupled to the power source, the second signal indicative of a characteristic of input power received at the second analysis circuit, analyzing, with the analysis circuitry, the first signal and the second signal, determining, whether an improper wiring condition exists at the input, in response to a determination that an improper wiring condition does not exist, providing output power to an output of the first UPS, and in response to a determination that an improper wiring condition does exist, de-energizing the first UPS.
Abstract:
A system for controlling an electricity supply to a load comprises at least one battery for storing energy. The system also comprises a controller for determining when to switch between a first mode wherein electricity is supplied to the load from a mains electricity circuit; and a discharging mode wherein electricity is supplied from the battery to the load via the mains electricity circuit. The determining is based on information associated with the electricity supply.
Abstract:
Aspects of the present disclosure involve systems, methods, and the like, for an energy interface system for interfacing alternative energy sources with a utility power source on a premises. The energy interface system provides flexibility in the use and distribution of utility energy sources and alternative energy sources based on several measurements and criteria of the interface system. For example, the energy interface system may allow for the energy consumption to adapt to changing parameters, such as utility rate schedules, cost of alternative fuels and utility premiums for consumption or generation of energy at particular times. The energy interface system also allows for deferment of charging or other high-energy loads to be recognized by the system at otherwise low-energy times. In addition, the energy interface system allows for monitoring and communication with the system for ease of configuring the system based on one or more criteria or measurements.
