You may make it perform. As a result, the amount of energy generated can be converted into the amount of gasoline and returned to the user, and energy saving awareness through energy creation can be increased.

  Here, the effect | action performed by the energy information management system 10 of this embodiment in which a process is performed as mentioned above is demonstrated concretely.

  First, in the information management device 12, energy creation is created by a device for creating energy creation such as the solar power generation device 22 provided in the house. Of the created energy, the amount of excess energy that is sold without being used is calculated from the detection result of the buying and selling power amount sensor 34.

  The created excess energy generation amount is accumulated every predetermined period and accumulated in the data accumulation unit 42 of each information management device 12. In addition, the excess energy creation amount is calculated every predetermined period, and the calculation result is accumulated in the center server 14.

  When the user wants to confirm how much the excess energy creation amount has been created in the house, the display unit displays the excess energy creation amount by operating the operation unit 44 of the information management device 12.

In the case of FIG. 5B, when the power difference is 100 Kwh, the EV travel distance of PHV is 5.0 km / Kwh, and the fuel efficiency of PHV is 20.0 km / liter, 100 Kwh × 5 km / Kwh / 20 km / Liter = 25 liters, and an example of displaying 25 liters when converted to gasoline is shown. In this way, by converting the excess energy creation amount into the distance traveled by the car and the amount of gasoline displayed on the monitor 50, the energy creation amount is expressed as a familiar travel distance and the amount of gasoline. Can be increased.

  In addition, when refueling at a member gas station where a contract for reducing excess energy creation is performed, a member store pre-registered in the navigation device 36 is selected and destination guidance is provided, so that the member store Be guided to. Here, in a member store such as a gas station, by acquiring an ID for identifying a user by inputting a card, an operation panel, etc., information on the excess energy creation corresponding to the ID is acquired from the center server 14, The value converted into the gasoline amount is displayed on the GS monitor 64.

  For example, as shown in FIG. 8, when the power difference is 400 Kwh, the EV travel distance of PHV is 5.0 km / Kwh, and the fuel efficiency of PHV is 20.0 km / liter, 400 Kwh × 5 km / Kwh / 20 km / liter = 100 An example of displaying 100 liters when converted to gasoline is shown. Here, by performing point reduction, gasoline discount, etc. and charging, it is possible to raise awareness of energy saving by energy creation for the user.

  Further, when refueling is performed here, for example, when the refueling amount for today is 50 liters, 100 liters−50 liters = 50 liters becomes the gasoline conversion value after refueling, so the gasoline conversion value exceeds the energy creation. By transmitting to the center server 14 as an amount, the value of the excess energy creation amount is updated, and the amount of reduction of the consideration for the excess energy creation amount is subtracted.

  In the present embodiment, the example in which the excess energy creation amount is reduced by converting the excess energy creation amount into a gasoline amount and performing a discount or the like has been described. However, the present invention is not limited to this example. The amount may be converted into predetermined points such as eco points, and points may be returned in cooperation with companies such as gasoline manufacturers, housing manufacturers, and automobile manufacturers. In addition, as a point return method, the center server 14 manages the cumulative value of the excess energy creation, and when the user accesses the center server 14, information such as a certificate representing the excess energy creation is obtained. Then, it may be output by printing or the like, and the points may be reduced such as discounting at the time of charging. Or you may make it apply to the user by applying the eco point of Unexamined-Japanese-Patent No. 2009-134450 already applied by this applicant, and you may make it apply another method.

  In the above embodiment, when the excess energy generation amount is converted into the gasoline amount, the example in which the electric energy is converted into the gasoline amount using the travel distance per kWh and the fuel consumption in the EV of PHV has been described. However, the conversion method is not limited to this, and for example, the amount of power of the excess energy creation may be converted into a charge, and the gasoline amount corresponding to the charge may be calculated. In this case, the information management device 12 or the navigation device 36 acquires gasoline price information from the member store via the network 18 or wireless communication, and obtains the gasoline amount that can be acquired by the excess energy creation amount and displays it on the monitor 50 or the like. This makes it possible to take into account fluctuations in gasoline prices. When the gasoline price information is different for each member store, the gasoline amount converted from the excess energy creation considering each gasoline price information may be displayed in a list for each member store. This makes it possible to select a member store to be used from among the member stores displayed in the list according to the user's will.

  In the above-described embodiment, the amount of energy generated by subtracting the amount of energy consumed at home from the amount of energy generated by the solar power generation device 22 is converted into the travel distance and gasoline amount of the car and displayed. The amount of energy generated is reduced, but the total amount of energy generated is converted into mileage and gasoline amount without subtracting energy consumption, and the value is reduced or reduced. It may be.
