PROBLEM TO BE SOLVED: To provide a storage battery control system and a power supply system, effectively utilizing a storage battery provided in the power supply system.SOLUTION: A storage battery 13 charges power supplied from a commercial power system A and a fuel power generator 11, and discharges and supplies the charged power to a load L. A control unit 13 performs at least one of preliminary discharge control to calculate an estimated charge amount of the storage battery 13 during a first target period, to discharge the storage battery 13 in a period before the first target period, in such a manner that the power storage amount of the storage battery 13 in the first target period comes to have a magnitude enabling charging the estimated charge amount, and preliminary discharge control to calculate an estimated discharge amount of the storage battery 13 during a second target period, to charge the storage battery in a period before the second target period, in such a manner that the power storage amount of the storage battery 13 in the second target period comes to have a magnitude enabling discharging the estimated discharge amount.SELECTED DRAWING: Figure 1 【課題】 電力供給システムに備えられている蓄電池を効果的に活用する蓄電池制御システム及び電力供給システムを提供する。【解決手段】 蓄電池１３は、商用電力系統Ａ及び燃料発電機１１から供給される電力を充電するとともに、負荷Ｌに対して充電した電力を放電して供給する。制御部１３は、第１対象期間における蓄電池１３の予測充電量を算出するとともに第１対象期間における蓄電池１３の蓄電量が予測充電量の充電が可能な大きさになるように第１対象期間よりも前の期間において蓄電池１３を放電させる事前放電制御と、第２対象期間における蓄電池１３の予測放電量を算出するとともに第２対象期間における蓄電池１３の蓄電量が予測放電量の放電が可能な大きさになるように第２対象期間よりも前の期間において蓄電池を充電させる事前充電制御と、の少なくとも一方を行う。【選択図】 図１
