PROBLEM TO BE SOLVED: To appropriately control a consumption power of a load and an output of a backup power-supply to reduce cost and elongate a backup time period.SOLUTION: A backup power-supply system 1 connected with a load (a base station )40 that operates by receiving supply of a power from a main power supply (a commercial power source 51), and supplying a power to the load 40 during the stop of the main power supply, comprises: an accumulator battery 20 whose battery residual quantity can be detected; a fuel cell 30 whose output is lower than a consumption power of the load 40 at a normal time; and a control device 10 acquiring battery residual quantity information of the accumulator battery 20 and information concerning an operation situation of the load 40, during the stop of the main power supply, restricting the operation of the load 40 depending on the battery residual quantity of the accumulator battery 20 and the operation situation of the load 40, and thereby, performing control so as to reduce the consumption power of the load 40. |
