Abstract:
An energy planning system that proposes an appropriate energy plan for a home includes: a sensor that senses a state of an energy facility in a home; a predictor that predicts a future lifestyle of a resident of the home; and a proposer that determines information about an energy plan for the home based on a result of the sensing by the sensor and the lifestyle predicted by the predictor, and outputs the information.
Abstract:
A storage cell management apparatus includes a power conversion unit, a determination unit, an allocation setting unit and a distribution unit. The power conversion unit is configured to perform an operation of storing power in a storage cell and an operation of discharging power from the storage cell. The determination unit is configured to determine an application of power discharged from the storage cell as one of a plurality of applications. The allocation setting unit is configured to determine an upper limit of an amount of power that can be supplied to each application, using a distribution ratio determined for the plurality of applications. The distribution unit is configured to supply the power stored in the storage cell for the application determined by the determination unit, with the power not exceeding the upper limit determined by the allocation setting unit for the application.
Abstract:
A price setting device includes: an acquisition unit that acquires a collection of forecast information; a price setting unit that determines unit prices of electricity during a target period; and a period setting unit that determines the target period. Each of the collection of forecast information is related to an area of areas (A1 to Az) to which at least one electric power supplier supplies electricity, and includes forecasted date and time if a corresponding area is to be affected by an anomalous event. The price setting unit is a unit price of electricity in an accommodating area to be higher than a unit charge in a target area during the target period. The target area is an area to be affected by the anomalous event. The accommodating area is an area capable of interchanging electricity with the target area.
Abstract:
A vehicle storage battery management device includes a charge level acquiring portion, a power capacity acquiring portion and, a power capacity deriving portion. The charge level acquiring portion acquires data of a charge level, which indicates a ratio of a capacity of a storage battery installed in an electric drive vehicle to a full charge capacity of the storage battery, from the electric drive vehicle. The power capacity acquiring portion acquires data of an amount of charging power supplied to the storage battery or data of an amount of discharging power discharged from the storage battery. The power capacity deriving portion derives a unit capacity of the storage battery based on the amount of charging power or the amount of discharging power, and a change in the charge level that occurs according to the amount of charging power or the amount of discharging power.
Abstract:
Vehicle power device supplies storage battery with charging power from power conversion circuit to charge it with connector attached to inlet of electric vehicle. Stress detector detects force exerted on junction by tensile strength of electric cable. Controller is configured: to start an output operation of charging power through power conversion circuit if the detected force is below a first threshold (K1); to raise an alarm through display and sound output device if the detected force is the first threshold (K1) or more when power conversion circuit outputs the charging power; and to stop power conversion circuit outputting the charging power if the detected force is a second threshold (K2) or more when power conversion circuit outputs the charging power, where K2>K1.
Abstract:
A meter device measures an amount of electric power received by a facility of a consumer from a power grid. A discharge device supplies, to a power wiring, electric power of a battery for travelling, which is mounted in an electric vehicle. A control device controls the discharge device so as to adjust an amount of electric power to be supplied to the power wiring from the battery. A communication portion of the control device acquires, through communication with the meter device, information regarding an amount of electric power as measured by the meter device. An adjustment portion of the control device adjusts the amount of electric power to be supplied from the battery to the power wiring so as to be equal to an amount of electric power corresponding to at least part of the amount of electric power measured by the meter device.
