Antenna coupling may be inductive and may operate in conformance to a wireless power and data transfer protocol. A transmission controller drives the transmitter antenna at an operating frequency, and either the wireless power transmission system or the wireless power receiver system may damp the wireless power transmission to create a data signal containing a serial asynchronous data signal.

An energy storage system (ESS) including a battery management system (BMS) arranged to monitor and control operations associated with charging and discharging electrical current from a storage element where the BMS is positioned within a cavity of a housing. A site controller coordinates operations of the ESS with a component of a power distribution system where the site controller is positioned within the housing's cavity. The storage element may include one or more battery cells. The ESS may include a frame defining the housing's cavity and including first and second side panels and a front access panel. The access panel may include at least one hinge in proximity to the first side panel where the hinge is arranged to prevent a portion of the hinge from extending beyond an edge of the first side panel as the access panel rotates from a closed position to an open position.

A control device of adjusting electric power remotely contains: multiple stations, multiple areas, at least one control module, and a content management system (CMS). A respective one station includes at least one load and at least one energy storage apparatus having at least one secondary battery. A respective one area includes the multiple stations. A respective one control module includes a microprocessor, a control unit, and a wireless communication unit. The CMS is configured to record and manage the respective one station and the at least one energy storage device and to command, control and order the respective one control module. The CMS is connected with the power supply unit and the respective one control module in a wirelessly and receives a power dispatching instruction sent from the power supply unit, and the power dispatching instruction has the respective one area, a starting time, and an ending time.

Controller (12) of power storage pack (10) communicates with controller (32) of electric moving body (30) in a state where power storage pack (10) is mounted to the electric moving body. Communication wiring (Lc1) connects a node of power line (Lp1) on power source terminal (Tp) side relative to first switch (RYp) and controller (12) of power storage pack (10). Overvoltage protection circuit (19) turns off second switch (SWc) inserted into communication wiring (Lc1) upon detecting an overvoltage of power line (Lp1) during communication between controller (12) of power storage pack (10) and controller (32) of the electric moving body.

A controllable electrical outlet may comprise a resonant loop antenna. The resonant loop antenna may comprise a feed loop electrically coupled to a radio-frequency (RF) communication circuit and a main loop magnetically coupled to the feed loop. The controllable electrical outlet may comprise one or more electrical receptacles configured to receive a plug of a plug-in electrical load and may be configured to control power delivered to the plug-in electrical load in response to an RF signal received via the RF communication circuit. The RF performance of the controllable electrical outlet may be substantially immune to devices plugged into the receptacles (e.g., plugs, power supplies, etc.) due to the operation of the resonant loop antenna. For example, degradation of the RF performance of the controllable electrical outlet may be less when the controllable electrical outlet includes the resonant loop antenna rather than other types of antennas.

A mesh network includes a plurality of nodes and a network head. The plurality of nodes includes a first node structured to generate and output a message to the network head in response to an event. The message includes at least one first information item associated with the first node, the electrical device monitored by the first node, or the section of the electrical distribution system monitored by the first node. The plurality of nodes includes a second node disposed on a communication path between the first node and the network head and being structured to add at least one second information item associated with the second node, the electrical device monitored by the second node, or the section of the electrical distribution system monitored by the second node to the message and to output the message to the network head.

A system providing connectivity management is provided. The system comprises: a content management server configured to manage connectivity for a network; one or more central controllers configured to collect connectivity information for at least a portion of the network for use by the content management server; and at least one outlet having one or more ports for receiving one or more plugs, wherein connectivity information is communicated between the outlet and the central controller through one or more wireless communication interface.

A system and method for restoring power in a closed-loop power distribution network. The network includes at least two power sources, at least one feeder and a plurality of switching devices positioned along the at least one feeder and being in communications with each other. The method performs a radial restoration process for restoring power and then determines that at least one of the sections is not receiving power after the radial restoration process has been performed. The method estimates power flow through each switching device and determines an available power capacity from each switching device. The method then determines if the unpowered sections can be powered by any of their neighbor and non-neighbor devices. The method virtually closes the switching devices to power the unpowered sections and updates the estimation of power flow through each switching device and determination of available power capacity from each switching device.

A system for wirelessly charging at least one device is disclosed. The device has a photovoltaic cell for converting incident light into electrical energy. The system also has a supply unit arranged to transmit a laser beam to the photovoltaic cell of the device. The supply unit is arranged to transmit the laser beam with a first divergence angle during a first mode and a second, narrower, divergence angle during a second mode following the first mode. The supply unit is arranged to change from the first mode to the second mode based on information relating to the location of the device.
