Abstract: A VGI system includes a plurality of BEVs, a plurality of pieces of EVSE, and a server. The server determines whether the BEV exchanges electric power with a power grid with the use of second EVSE provided in a second area, the second area being different in manner of management of power supply by the power grid from a first area where predetermined first EVSE is provided, the first EVSE being normally used by the BEV. When the server determines that the BEV exchanges electric power with the use of the second EVSE and when the second area is higher than the first area in contribution to DR in exchange of electric power by the BEV, the server grants an incentive higher than in exchange of electric power with the power grid with the use of the first EVSE.

Abstract: An operation management server manages a vehicle equipped with a battery able to store regenerated electric power. The operation management server includes: a processor that generates a message to be transmitted to the vehicle; and a storage that stores traveling histories of a plurality of vehicles. The processor estimates a transition in a power storage amount of the battery on a planned travel route of the vehicle based on a travel plan of the vehicle and the travel histories of the vehicles. The processor generates the message for proposing execution of external power supply from the battery to an outside of the vehicle before the power storage amount reaches a predetermined amount, when an estimation is made that the power storage amount will exceed the predetermined amount on the planned travel route.

Abstract: A server includes an acquisition unit configured to acquire information on power control including at least one of power supply from an electrified vehicle to an electric power system and charge from the electric power system to the electrified vehicle, and a control unit configured to control display during use of an Internet service with a terminal owned by a user of the electrified vehicle. The control unit is configured to, when the electrified vehicle accedes to a request to perform the power control, generate a program command to reduce display of advertisements on the terminal as compared to when the electrified vehicle does not accede to the request to perform the power control.

Abstract: A power management apparatus includes a communication unit (acquisition unit) that acquires information about supply and demand of electric power for a power bank (power storage device), and a processor (controller) that controls electric power received by an electric vehicle from the power bank. The processor sets a power exchange ratio of electric power received from the power bank to electric power supplied to the power bank, depending on the supply and demand of electric power. The processor determines an amount of electric power to be received by the electric vehicle from the power bank, based on an amount of electric power supplied from the electric vehicle to the power bank, and the power exchange ratio.

Abstract: A hot-dipped aluminum coated steel sheet including, on the surface thereof, a coating layer consisting of 2 to 15 wt % of Si, not greater than 1.2 wt % of Fe, 0.005 to 0.6 wt % of Mn, 0.002 to 0.05 wt % of Cr and the balance of Al and unavoidable impurities, and an alloy layer disposed between the coating layer and the steel sheet, having a thickness of not greater than 7 .mu.m and having a mean composition consisting of 20 to 50 wt % of Fe, 3 to 20 wt % of Si, 0.1 to 10 wt % of Mn, 0.05 to 1.0 wt % of Cr and the balance substantially consisting of Al. This steel sheet can be produced by conducting coating in a coating bath consisting of 3 to 15 wt % of Si, 0.5 to 3.5 wt % of Fe, 0.05 to 1.5 wt % of Mn, 0.01 to 0.2 wt % of Cr and the balance substantially consisting of Al, or by adjusting the sum of the concentrations of Zn and Sn in the impurities in the coating layer to not greater than 1 wt %.
