Abstract: An energy management system has an integration control portion that performs control to charge a storage battery with a power of such an amount that a power consumption including a power supplied by a supply portion is equal to or smaller than a target value indicated by power consumption target information recorded in a recording portion when a power consumption detected by a detection portion is smaller than the target value, and to supply a building with a power with which the storage battery is charged such that the power consumption including the power supplied by the supply portion coincides in amount with a power equal to or smaller than the target value indicated by the power consumption target information recorded in the recording portion when the power consumption detected by the detection portion is larger than the target value.

Abstract: A charging start time and preliminary air conditioning time are calculated based on the departure time that is set with a control/operation device (S108), and the charging time and preliminary air conditioning time are set (S110). Then, a control is executed to start charging when at the charging start time (S112 to 116) and preliminary air conditioning may be started when the amount of charge is sufficient for preliminary air conditioning and a preliminary air conditioning starting trigger is detected, that is locking or preparation for leaving house is detected, for example (S118 to 128).

Abstract: Use start date-and-time is input by use of U1. Times T1 and T2 to achieve SOC 1 and SOC 2 are set. Charging is started at T2 and is continued until it is determined that SOC 2 is achieved. Thereafter, charging is started at T1 and continued until it is determined that SOC 1 is achieved by the input use start date-and-time.

Abstract: An electricity charging system includes: a charger portion that charges a storage battery; a detection portion that detects an amount of charge stored in the storage battery; and a control portion that controls electric power that is supplied to charge the storage battery by the charger portion so that the electric power changes by a predetermined rule, according to the amount of stored electricity detected by the detection portion.

Abstract: A charge instructing device installed in a space such as an indoor space in which the security is ensured reads key information (ID) stored in a vehicle key held in a key holding unit and transmits the read ID to an electric powered vehicle. Electric powered vehicle performs authentication by checking the ID transmitted from charge instructing device against registration information stored in advance. The result of the authentication is then transmitted from electric powered vehicle to charge instructing device. Charge instructing device permits a charger to charge electric powered vehicle according to the result of the authentication transmitted from electric powered vehicle.

Abstract: An HV-ECU acquires electric power information from an electricity transmission line by using a modem. The electric power information includes information regarding the amount of carbon dioxide having been emitted in the generating process of the commercial electric power supplied from an electricity transmission line. When the CO2 emission amount is below a pre-set CO2 emission amount, the HV-ECU inputs the commercial electric power, and outputs a command to charge an electricity storage device to a motive power output device, so that the motive power output device executes a charging control of the electricity storage device.

Abstract: A charger can read an ID code from a transponder key of an immobilizer system of a contract vehicle. When an owner of the vehicle connects a vehicle and charger with a charging cable and brings the transponder key close to a reading portion, the read ID code is transmitted from charger toward vehicle where authentication is performed. Vehicle transmits an authentication result to charger. Preferably, these transmission and reception can be performed by power line communication employing a vehicle cable.

Abstract: An information apparatus of a vehicle that allows the request for the required information to be reliably made is provided. When a vehicle and a charging device are connected to each other for transmission and reception of electric power in order to charge a main battery, a main control ECU receives the contents from a server depending on the contents requesting information stored in a request storing unit and stores the received contents in a contents storing unit. Preferably, prior to receiving the contents, the main control ECU notifies of the content of the contents requesting information to inquire of an operator performing the charging whether the contents are received based on the contents requesting information.

Abstract: A control device controls first and second inverters such that alternating voltage is generated across neutral points of first and second motor generators. When the value of a signal representative of the remaining amount of fuel in a fuel tank becomes lower than a predetermined threshold value, the control device controls the first and second inverters such that the voltage level of the alternating voltage is changed in order to notify a user external to the vehicle of the low remaining amount of fuel.
