A vehicle-mounted charging device (12) includes a vehicle-mounted battery (18), a vehicle-mounted electronic control unit (30) and a modem startup control unit. The vehicle-mounted battery is charged with power supplied from external charging equipment via a charging cable (16). The vehicle-mounted electronic control unit is configured to perform charging communication, relating to charging of the vehicle-mounted battery, with the external charging equipment using an in-band modem (32). The modem startup control unit starts up the in-band modem when the vehicle-mounted electronic control unit performs the charging communication, and that stops a startup of the in-band modem when the vehicle-mounted electronic control unit does not perform the charging communication.

A system and method for inferring schematic and topological properties of an electrical distribution grid is provided. The system may include Remote Hubs, Subordinate Remotes, a Substation Receiver, and an associated Computing Platform and Concentrator. At least one intelligent edge transmitter, called a Remote Hub Edge Transmitter, may transmit messages on the electrical distribution grid by injecting a modulated current into a power main that supplies an electric meter. The Subordinate Remotes, Remote Hubs, the Substation Receiver, and the associated Computing Platform and Concentrator may contain processing units which execute stored instructions allowing each node in the network to implement methods for organizing the on-grid network and transmitting and receiving messages on the network. The Substation Receiver, Computing Platform and Concentrator may detect and infer schematic grid location attributes of the network and publish the detected and inferred attributes to other application systems including geospatial information systems maintaining the logical and physical network model.
摘要:
A system and methods for optimizing the performance of communication network utilizing an electrical distribution grid are disclosed. Optimization methods may include archiving historical message data and metrics from transmissions by Remote Hubs received on one or more Substation-to-Edge channels. Trends in the archived metrics over time are later analyzed to determine which combination of transmission variables such as frequency band, modulation method, drive voltage, and transmission time produce the highest message success rates overall. The results of such analysis may be used to provide feedback to the Remote Hubs or reveal necessary repairs to the network. Optimization may also be carried out locally by an individual Remote Hub by estimating the impedance of the transmission medium and adjusting either drive voltage or transmission band.

摘要:
For an array of installed energy harvesting devices, a method of gathering information about individual devices in the array and generating a layout or map of the installed devices based on the gathered information is provided. A communications gateway or a base station gathers the information and determines the positions of individual micro-inverters. The gathered information is used to generate a topological or geometrical map of the installed devices.
