  • Patent number: 9469203
    Abstract: Battery information output equipment allows a driver of an electric vehicle 10 of an electricity consumer 2, now parked, to input what battery capacity is required at two or more points of time on or before the time at which the electric vehicle is scheduled to come into use, considering an operation schedule for the vehicle, and transmits the usable capacity at each point of the times, i.e., maximum capacity minus capacity required at each point of the times, to a power supply/demand management center 3, so that charge and discharge of a battery 17 is controlled by a charge/discharge command from the power supply/demand management center 3 such that use of battery capacity for power supply and demand leveling is kept within the usable capacity at any point of the times.

  • Patent number: 9340117
    Abstract: The invention judges a total power supply/demand condition of the electricity consumers 2 as a whole according to an individual power supply/demand condition of electricity consumers 2, judges a total usable capacity of all batteries 17 according to a usable capacity of the batteries 17 of electric vehicles 10 parked at electricity consumers 2, obtains required charge/discharge amounts of all the batteries 17 according to a result of comparison of the total power supply/demand condition of the electricity consumers 2 as a whole with the total usable capacity of all the batteries 17, subjects the batteries 17 to charge/discharge controls according to the required charge/discharge amounts, the power supply/demand conditions of the electricity consumers 2, and the usable capacities of the batteries.
