Apparatus and method for managing energy information profile of home based on smart plug

Abstract: The present invention relates to an apparatus and method for managing a home energy information profile based on a smart plug. According to the apparatus for managing a home energy information profile based on a smart plug according to the present invention, it is detected that an energy load device is plugged in or plugged out of the smart plug without adding an additional device such as an RFID tag, and an energy information profile is transmitted to a home energy management server when a corresponding event occurs, so that a user immediately change shape information of the energy load device. According to the present invention, a smart plug manages shape information on a load device plugged in or plugged out of the smart plug on the basis of a plugging in/plugging out event so that information on the load device may constantly match information stored in a home energy management server. Furthermore, energy information on the energy load device may be correctly managed based on the smart plug without adding an additional device such as an RFID.

Towards distributed enthalpy measurement in large-scale air conditioning systems

Abstract: Air conditioning systems are among the major energy consumers in buildings. Energy-efficient operation of AC systems is an important step towards better energy management in building automation, but requires efficient monitoring of the energy or enthalpy flows within the AC installation, which is currently still difficult because of the lack of appropriate equipment. This paper introduces a distributed data acquisition system for large-scale AC systems based on low-cost flow sensors implemented by means of standard printed circuit board technology and interconnected via a wireless sensor network. A critical issue for the system installation is the placement of the sensors in the air ducts to obtain representative measurements of the air flow. To this end, extensive aerodynamical simulations are carried out to analyze the flow distributions in typical building blocks for air ducts, particularly with respect to turbulences. The simulation results are compared with experimental data from the literature and are shown to be reliable.

Configurable hybrid energy storage system and method

Abstract: An energy management module (EMM) configured to electrically interconnect at least one first energy storage unit, at least one second energy storage unit, and a power bus; and configured to select a mode of operation. Each first energy storage unit has a first permissible charge rate; each second energy storage unit has a second permissible charge rate less than the first permissible charge rate. Under an energy storage mode of operation, the EMM is configured to allocate electrical current from the power bus among the first and second energy storage units. Under an energy balance mode of operation, the EMM is configured to transfer electrical charge among the first energy storage unit(s) and the second energy storage unit(s). Under an energy discharge mode of operation, the EMM is configured to deliver electrical current from the first and second energy storage units to the power bus.

Energy and power management integrated circuit device

Abstract: Provided is an energy and power management integrated circuit (IC) device. The energy and power management IC device includes a plurality of energy conversion devices for harvesting energy from respective energy conversion sources and converting the energy into electric energy, an energy management IC (EMIC) for converting the electric energy converted by the energy conversion devices into stable energy, a storage device for storing the energy or power converted by the EMIC, a power management IC (PMIC) for receiving and distributing the power stored in the storage device, and a plurality of output load devices for consuming the power distributed by the PMIC. Accordingly, it is possible to harvest energy in an environmentally friendly way and semi-permanently use the energy without changing a battery.
