A power receiving device may include a billing processing unit, a power control unit, and a notice control unit.

Abstract: Devices, methods, and programs for providing a notice indicating whether a device supports an authentication function. A method for providing notice may include performing communication with a device, making a determination whether the device is a power supply target, selectively transmitting power to the device based on a result of the determination, and providing a notice indicating whether the device supports an authentication function based on the result of the determination. A power supply device may include a communication unit, a determining unit, a power control unit, and a notice control unit. Another method for providing notice may include performing communication with a device, and providing a notice indicating whether the power supply device supports the authentication function based on a result of the communication. A power receiving device may include a communication unit and a notifying unit.

Abstract: There is provided a management apparatus for an electrical apparatus, the management apparatus including a communication unit configured to receive conduction state information from an electrical apparatus, a storage unit configured to store reference conduction state information of the electrical apparatus, and a determination unit configured to compare the conduction state information of the electrical apparatus with the reference conduction state information of the electrical apparatus to determine a state of the electrical apparatus.

Abstract: A physical-quantity receiving method includes: providing, during receipt of a physical quantity, a user with a notification that the user is under obligation to make payment for the received physical quantity, and providing the user with an inquiry about whether to continue receiving the physical quantity; and making payment for the physical quantity per a unit time by electronic money after a lapse of the unit time, or making payment for a unit physical quantity by electronic money after receipt of the unit physical quantity, when continuing receipt of the physical quantity.

Abstract: A battery control unit includes: a storage section holding remaining amount data that indicates a remaining amount of a battery; and a control section managing the battery in a fashion of separating the battery into a first region and a second region, by a way of separating the remaining amount data into first remaining amount data and second remaining data and of allowing the storage section to hold the first and second remaining amount data.

Abstract: There is provided a power consumption management device including a power measurement unit configured to measure power consumption of an electrical device, an environmental factor measurement unit configured to measure a factor of an environment in which the electrical device is used, a storage unit configured to store a predicted value related to the power consumption in which a value of the factor of the environment is designated as a parameter, and a calculation/control unit. The calculation/control unit obtains the predicted value related to the power consumption stored in the storage unit based on the value of the factor of the environment measured by the environmental factor measurement unit and compares the obtained predicted value related to the power consumption to an actual measurement value related to the power consumption obtained based on a power consumption value measured by the power measurement unit.

Abstract: There is provided a power management device including a storage unit configured to hold a correspondence relationship between first identification information held by a power supply target and second identification information held by a user in advance, and a power management unit configured to issue a power supply instruction to a power supply device that supplies power to the power supply target based on the correspondence relationship between the first identification information and the second identification information.

Abstract: There is provided an energy management device that sets a priority in a plurality of electric devices when power limitation is performed, receives a status signal from a predetermined electric device that is a priority changing target, and generates a control signal configured to change the priority of the predetermined electric device to be higher based on the status signal when the power limitation is performed.

Abstract: There is provided an information processing device including a characteristic detection unit that detects a characteristic of a battery and a characteristic of an operating device that operates using electric power obtained from the battery, a symbol setting unit that sets one symbol on which information corresponding to the detected characteristics is reflected, and a display control unit that causes the set symbol to be displayed.
