20110282513 | SYSTEM, APPARATUS AND METHOD FOR CONTROLLING CHARGE AND DISCHARGE OF ELECTRIC VEHICLE - Disclosed is a technique using an electric vehicle. The technique enables a user to set the operation plan of the electric vehicle and the price of electricity used to charge/discharge an electric vehicle battery. The electric vehicle battery is charged, or the electric energy charged in the electric vehicle battery is collected, according to the set information. Accordingly, it is possible to charge the electric vehicle battery at the price approved by the user under variable pricing of electric energy. When the price of electricity increases or there is no operation plan of the electric vehicle, the electric energy stored in the battery is collected to operate electric devices or resell the stored electric energy to an electric power company, thereby obtaining economic benefit. As the spread of electric vehicles are extended, it can be expected to save a considerable amount of electric energy throughout the whole society. | 11-17-2011 |

Then, the repeater analyzes and manages the energy consumption rate of the individual user using the received information, and transmits information on the energy consumption rate to the meter or the central management server. The repeater may also analyze various information such as information on an energy consumption propensity of the individual user. The repeater immediately transmits essential information but transmits incidental information only when there is a request of the meter or the central management server. Accordingly, it is possible to reduce communication traffic between the central management server and the plurality of meters. | 03-08-2012 |
20120059533 | SYSTEM FOR REMOTELY MANAGING ELECTRIC VEHICLE - In a system for remotely managing an electric vehicle, a meter related to charge of the electric vehicle, installed in each parking lot, and a meter installed in each home communicate information related to the electric vehicle using a communication network constructed for the purpose of energy management. The meter in each home is linked with an in-home display (IHD) device installed in the home, and a user identifies and manages, in the home, information of the user's own electric vehicle through the IHD device.

20120059609 | SYSTEM FOR ELECTRIC ENERGY MANAGEMENT - A system for electric energy management inspects admittances or impedances at several positions on the same power line, and determines the presence of electricity theft based on them. Particularly, each of the admittances or impedances is calculated based on information on an amount of electricity measured by each watt-hour meter. Since information on amounts of electricity respectively measured at an upper place and several lower places on the same power line have a certain correspondence relation, the calculated admittances or impedances also have a relation. For example, the admittance or impedance at the upper place is necessarily corresponds to the equivalent value of the admittances or impedance at the lower places. Thus, it is possible to precisely determine the presence of electricity theft by monitoring whether or not the difference value is within an acceptable range in consideration of an error of measuring the amount of electricity, or the like. | 03-08-2012 |
20120059610 | ENERGY METERING SYSTEM, APPARATUS AND METHOD - Disclosed is an energy metering system, apparatus and method that enables an energy meter to reduce power consumed in communication when remotely inspecting the energy meter under an energy pricing system changed depending on time. To this end, the energy meter transmits information on energy consumption at only a changed time of energy price, and operates in a power saving mode except the changed time. If the information on the energy consumption is transmitted at the changed time, the information on the energy consumption in each period having the same energy price is secured, and therefore, a central server has no difficulty in calculating an energy consumption rate. Thus, it is possible to minimize power consumed in communication while transmitting all the information on the energy consumption, required in the central server. Particularly, a battery is used longer in an environment using the battery, thereby reducing maintenance/repair cost. | 03-08-2012 |
20120059775 | ENERGY METERING SYSTEM, ENERGY METERING METHOD AND WATT HOUR METER OF SUPPORTING DYNAMIC TIME-VARYING ENERGY PRICING - The present disclosure is disclosed to record in detail and manage information on energy use history of a user under various energy pricing systems where energy prices are changed in time. To this end, an energy meter receives time-based energy price information from a remote server, and time-sequentially records a record including time information of relevant unit time for each unit time, energy price information applied to relevant unit time and energy consumption information at the relevant unit time, whereby the information on how much, when and at what price the user has used the energy can be accurately and quite obviously managed. The energy use history can be used in various fields as data for promoting reasonable energy use, and as a base for calculating energy use charge. | 03-08-2012 |
20120060151 | SYSTEM AND METHOD FOR UPDATING FIRMWARE - The present disclosure can update firmware of home electronic devices using an energy meter installed at each energy consumer house. The energy meter receives firmware from a remote server managing the firmware of home electronic devices and transmits the firmware to home electronic devices. The energy meter may bypass the firmware of the home electronic devices received from the remote server, or pre-download and transmit to the home electronic devices at a time the update is to be implemented. | 03-08-2012 |
20120060152 | SYSTEM AND METHOD FOR FIRMWARE UPDATE OF METER, WATT HOUR METER WITH FUNCTION OF REMOTE FIRMWARE UPDATE - According to the present disclosure, an energy meter installed at each energy consumer receives in advance a new firmware from a remote server, and updates its own firmware at a future time. The energy meter may receive update time information designating a future time when downloading the firmware, or may execute the update in response to update execution instruction from the remote server once the firmware is downloaded. The firmware update may be executed for each module unit. Communication traffic can be dispersed because the download is given to each energy meter in advance before a time firmware or firmware module update is to be executed. A large load is prevented from being loaded to the remote server at once. It is easy to manage or control a plurality of energy meters because the update can be executed in a lump. | 03-08-2012 |
20120232816 | APPARATUS AND METHOD FOR ENERGY DISPLAY - The present disclosure enables comparison of an energy consuming propensity of each energy consumer with that of other energy consumers. To this end, energy usage information of each energy consumer and comparison conditions (size of house, the number of families, energy consuming regions) are collected, and energy consuming propensities of other energy consumers are compared with energy consuming propensity of each energy consumer similar in terms of living environment, and the comparison is shown. A variety of statistical information for comparison is provided through an IHD (In-Home Display) installed at each house, whereby the energy consumers can easily and conveniently evaluate his own energy consuming propensity. An objective evaluation of his or her position related to energy consumption of other energy consumers promotes more active energy conservation and more rational energy consumption by being stimulated by the energy consumption of other energy consumers. | 09-13-2012 |
