Abstract: A charge/discharge control apparatus includes: a controller which performs a discharge control to discharge a rechargeable battery and a charge control to charge the rechargeable battery using excess power which is power, among generated power, which is not to be consumed by a load; and a setter which sets a threshold value for remaining energy in the rechargeable battery, according to a planned discharged energy amount which is planned as a discharged energy amount to be supplied from the rechargeable battery to the load during a specified time period. The controller performs a discharge prohibition control to prohibit a discharge of the rechargeable battery when the remaining energy in the rechargeable battery is equal to or below the threshold value prior to the specified time period.

Abstract: A power management method includes: receiving a surplus power value, indicating an amount of surplus power; receiving an inquiry regarding a power supply using the surplus power in a first time period; and issuing, in accordance with the inquiry, first power identification information in association with an accumulated value of the amount of surplus power corresponding to the first time period, the first power identification information allowing a power supply apparatus to supply power using the surplus power corresponding to the first time period. When a first power supply request associated with the first power identification information and requesting a power supply to a first load is received, the power supply apparatus is caused to supply an amount of power equal to or smaller than the accumulated value of the amount of surplus power, to the first load, as first power that does not cause a fee charging process.
