Patent number: 9600009Abstract: A method and system for managing an energy supply of a utility provider include calibrating one or more climate controlled spaces for a controller. The calibrating may include calculating a heating/cooling ratio for the one or more climate controlled spaces. After this calibration occurs, the system may determine if an energy supply surplus exists. If an energy supply surplus exists, then the system may start using the one or more climate controlled spaces as energy sinks for expending energy according to the heating/cooling ratio. The system may also determine if an energy supply deficit exists and if an energy supply deficit exists, then the system may start using the one or more climate controlled spaces as energy “sources,” in which a direct load control algorithm is used to reduce energy consumption by the one or more climate controlled spaces.Type: GrantFiled: October 6, 2013Date of Patent: March 21, 2017Assignee: COMVERGE, INC.Inventors: John Rossi, Wendell Miyaji

Patent number: 9002524Abstract: A system for establishing local control of a space conditioning load includes a switch for controlling a flow of energy for a space conditioning load. Control logic is operatively coupled to the switch, for receiving control parameters associated with a direct load control event from a utility provider. The control logic may also measure room temperature based on received temperature signals and determine if a room temperature is greater a comfort temperature range. The control logic may eliminate operation of a direct load control program if the room temperature is greater than or equal to the comfort temperature range. The control logic may log and signal back to the utility provider that the comfort temperature range is exceeded. The control logic may then restore local control of the switch and initiate a temperature setback control to a thermostat for the remainder of the control period.Type: GrantFiled: December 9, 2012Date of Patent: April 7, 2015Assignee: Comverge, Inc.Inventor: Howard Ng

Patent number: 8963492Abstract: A method and system provide for the cooperative charging of electric vehicles. By using power line communications, chargers of the electric vehicles who are serviced by the same distribution transformer can form self-contained local area networks due to the nature of power line communications. After the chargers of the electric vehicles are coupled to one another through power line communications, they can form a token ring network. According to this token ring network, a predetermined number of tokens can be assigned within the token ring network for permitting chargers with tokens to charge respective electric vehicles while chargers without tokens must wait until they receive a token to initiate charging.Type: GrantFiled: December 18, 2011Date of Patent: February 24, 2015Assignee: Comverge, Inc.Inventor: John Rossi

Patent number: 8903553Abstract: A method and system for controlling a unitary room air conditioner and for reducing peak loads can comprise a communications transceiver coupled to a relay or switch. This relay or switch can control the flow of electricity to a compressor of the air conditioner. The communications transceiver can receive signals which may direct the communications transceiver to open or close the relay or switch. In this way, the compressor can be controlled independent of the air conditioner's control logic. In other words, the operation of the compressor can be controlled with signals which originate outside of the unitary air conditioner and independent of the air conditioner's own internal control logic.Type: GrantFiled: May 1, 2009Date of Patent: December 2, 2014Assignee: Comverge, Inc.Inventors: Wendell Miyaji, John Rossi
