A charging system based on a master-slave relationship includes a master charging device coupled with a target device, and at least one slave charging device electrically connected with the master charging device. An edge slave charging device among the at least one slave charging device is coupled with a power source. The master charging device determines a power-output distribution of the master charging device and the at least one slave charging device, and notifies the at least one slave charging device of the power-output distribution. The at least one slave charging device provides a supplementary power to the master charging device according to the power-output distribution. The master charging device further provides a specific power for the target device based on the supplementary power, so as to charge the target device in cooperation with the at least one slave charging device.

An intelligent circuit breaker is electrically capable of dimming a load using sine wave dimming and forward or reverse cut-phase dimming. The intelligent circuit breaker may include low on resistance transistors switching at a 100 kHZ or higher using pulse width modulation to achieve the sine wave dimming while filtering out the high frequency switching and allowing a line frequency pass through. The intelligent circuit breaker may include a wireless module for receiving one or commands to perform power dimming of the load. The intelligent circuit breaker may advantageously be constructed in a form factor which is compatible with standard circuit breaker panels.

A system and method for remotely monitoring, measuring and controlling power to an electrically powered device with the use of a temperature sensor is disclosed herein. The temperature sensor is configured to transmit temperature readings for room temperatures to the central command computer to prevent harm to equipment within the facility, wherein the central computer is configured to perform reactive operations for other equipment in order to prevent damage to the other equipment based on the temperature readings received from the temperature sensor.

A group of homes, businesses, or other electric power consuming premises are aggregated and commonly controlled to dynamically reduce loads in sufficient quantities, and with sufficient rapidity and duration, to participate as a market participant in the energy markets including participating as a peaking power plant. While the amount of reduced power consumption for a single premises is typically quite small, the total reduced consumption of an aggregation of just a few thousand homes or businesses may be on the order of hundreds of kilowatts. A premises power controller in conjunction with intelligent circuit breakers, which may include dimmers, enable dynamic management of individual loads in each premises.

An intelligent circuit breaker electrically is capable of being actuated and interfacing with a conventional circuit breaker. The intelligent circuit breaker includes a wireless transceiver for communicating with other intelligent circuit breakers, a breaker controller, memory, and a display. The memory may be used to temporarily store data of interest regarding the intelligent circuit breaker's status, power consumption, operating history, and the like. The intelligent circuit breaker may advantageously be constructed in a form factor which is compatible with standard circuit breaker panels.

A mobile terminal, a master data communication device and a mobile terminal charging system and method are provided. The method includes that: a mobile terminal determines whether or not a power supply device is a master data communication device and, if so, determines an appropriate charging mode for charging the mobile terminal. The disclosure not only enables a mobile terminal to select a plurality of adjustable charging modes to charge the mobile terminal but also enables the terminal to select a most appropriate charging mode to charging the mobile terminal, thus improving the charging efficiency.

The methods and apparatus described enable automatic configuration, or commissioning, of controller devices and load control devices through a low voltage communication network controlled by one or more controller devices. These methods and apparatus further enable expansion of the load control system by connection of additional loads and or load control devices and or controller devices which will reinitialize the low voltage communication network and automatically reconfigure the controller devices and load control devices connected to the network.

A controller, process, and apparatus can be configured to provide backup electrical power to various equipment used in hydrogen and/or ammonia production in response to a loss of power condition being detected. The loss of power can be due to unavailable power from renewable sources (e.g. cloudy day, non-windy conditions) or due to other power transmission problems. The backup electrical power can be provided in a way that can reduce the carbon intensity associated with the providing of the backup power. The backup power can also be provided to help avoid degradation of equipment that can occur from sudden losses of electrical power. In some embodiments, hydrogen powered turbines, hydrogen fuel cells, biofuel generators, and/or hydrogen powered engines can be utilized for providing the backup power.

The priority of a demand regulating control for a device is changed in accordance with a simple operation by a consumer. A demand regulating system has an operation unit that selects from among a plurality of consumption devices, on the basis of priority information and a regulating quantity, a plurality of control-target devices, which are targeted for demand regulating control reducing consumption of the resource. A control unit executes the demand regulating control on the basis of a control instruction; and an input unit receives a first operation by the consumer, and transmits first request information requesting a change in the priorities of the plurality of control-target devices, to the operation unit in accordance with the first operation. The operation unit, upon receiving the first request information, specifies the plurality of control-target devices, and changes the priorities of the plurality of control-target devices in the priority information.
