A higher usage fee is set for external supply power as predetermined contract power increases. A battery management system includes: a contract power information acquisition section configured to acquire contract power information indicating the contract power; a power-in-use estimation section configured to estimate power in use in the storage plant in a target time zone in future; a discharge plan creation section configured to create a discharge plan in which discharge power from the battery is supplied as power to be used in the storage plant when the power in use in the target time zone exceeds the contract power; and a discharging control section configured to discharge the battery on the basis of the discharge plan. The power in use in the target time zone is estimated by the power-in-use estimation section.

A method for manufacturing a carbon fiber sheet, the method including a carbon fiber forming step of heating a resin sheet to a carbonization temperature at a heating rate of 15,000&#xb0; C./sec or higher, thereby forming a carbon fiber from the resin sheet. In the carbon fiber forming step, the resin sheet is preferably irradiated with an energy ray having an output density of 130 W/mmor higher and an amount of irradiation energy of 0.05 J/mmor more.

An electrolyte membrane thickness measurement apparatus includes a detecting medium supplying portion configured to emit a detecting medium, a detecting portion configured to detect a metal catalyst, and an analyzing unit. A thickness direction profile of a detection signal is generated by the detecting portion, and first and second inflection points are determined in the thickness direction profile based on the intensity of the detection signal by the analyzing unit. The distance between the first and second inflection points is evaluated as the thickness of the electrolyte membrane by the analyzing unit.
