Battery information output equipment allows a driver of an electric vehicleof an electricity consumer, 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, so that charge and discharge of a batteryis controlled by a charge/discharge command from the power supply/demand management centersuch that use of battery capacity for power supply and demand leveling is kept within the usable capacity at any point of the times.

Battery information output equipment for power supply and demand leveling system

The invention judges a total power supply/demand condition of the electricity consumersas a whole according to an individual power supply/demand condition of electricity consumers, judges a total usable capacity of all batteriesaccording to a usable capacity of the batteriesof electric vehiclesparked at electricity consumers, obtains required charge/discharge amounts of all the batteriesaccording to a result of comparison of the total power supply/demand condition of the electricity consumersas a whole with the total usable capacity of all the batteries, subjects the batteriesto charge/discharge controls according to the required charge/discharge amounts, the power supply/demand conditions of the electricity consumers, and the usable capacities of the batteries.

Power supply and demand leveling system

A load distribution system includes a plurality of servers, each having a memory device in which are stored a plurality of data files for transmission to a plurality of client stations, and a control server which is connected to the plurality of servers for controlling the distribution of transmission requests from client stations as loads on the servers by acquiring transmission counts for data files that are transmitted by the plurality of servers, and determining which server should respond to a transmission request as a data transmission server based on which server has a transmitted data count which is the smallest.
