A backup power system according to the present disclosure comprises a battery, a charging circuit, an electricity storage unit, a first load, a second load, and a control unit that controls the charging circuit. The control unit increases the input current of the charging circuit at a first rate of change in response to a start-up signal. Upon detecting that the charging voltage of the electricity storage unit has risen to a first voltage at which the first load can be driven, the control unit controls the charging circuit so that the input current of the charging circuit is increased at a second rate of change lower than the first rate of change. The charging circuit is controlled by the control unit so that the input current increases at the second rate of change, and the charging voltage of the electricity storage unit rises to a second voltage at which both the first load and the second load can be driven.
本公开的备用电源系统具备蓄电池、充电电路、蓄电部、第一负载、第二负载以及控制所述充电电路的控制部。所述控制部响应于启动信号来使所述充电电路的输入电流以第一变化率上升。当所述控制部检测到所述蓄电部的所述充电电压上升到能够驱动所述第一负载的第一电压时,所述控制部控制所述充电电路,以使所述充电电路的所述输入电流以比所述第一变化率低的第二变化率上升。所述充电电路被所述控制部控制为所述输入电流以所述第二变化率上升,所述蓄电部的所述充电电压上升到能够驱动所述第一负载及所述第二负载这双方的第二电压。
