The backup power supply system (1) supplies power to one or more loads (3) when the power supply (2) fails. A backup power supply system 1 includes a plurality of power storage devices C1 and a switching unit 12. The plurality of power storage devices C1 are charged by a power source 2. The switching unit (12) switches the electrical connection between the plurality of power storage devices (C1) to a first state in which the plurality of power storage devices (C1) are connected in parallel with the power source (2) or a second state in which the plurality of power storage devices (C1) are connected in series with each other. A switching unit (12) switches the electrical connection to a first state when the plurality of power storage devices (C1) are being charged, and switches the electrical connection to a second state when the power supply (2) has failed.
备用电源系统1在电源2发生了故障的情况下向一个或多个负载3供电。备用电源系统1包括多个电力存储设备C1和切换单元12。多个电力存储设备C1由电源2进行充电。切换单元12将多个电力存储设备C1之间的电连接切换为多个电力存储设备C1与电源2并联连接的第一状态或多个电力存储设备C1彼此串联连接的第二状态。切换单元12在多个电力存储设备C1正在被充电时将电连接切换为第一状态,并且在电源2发生了故障时将电连接切换为第二状态。
