To provide a power supply system for which it is not necessary to alter hardware even in a case where a system configuration of an IoT system consisting of multiple load apparatuses to which power is supplied from the power supply system, is changed and it is necessary to change the number of output terminals, voltages of the output terminals, ON/OFF control timing of power, a battery to be connected as a power source and the like.SOLUTION: On the basis of information in information storage units 122-124 storing therein voltage information to be allocated to external output terminals 111-114, ON/OFF information, switching timing and a switching method of the external output terminals 111-114, a power supply system control unit 130 switches voltages and ON/OFF of the external output terminals 111-114 and even in a case where batteries 141-143 of different voltages are defined as a power source, voltage information of the batteries is stored in a power source information storage unit 121, thereby measuring a residual battery power capacitance and a deterioration state without altering hardware of a power supply system.SELECTED DRAWING: Figure 1 【課題】電源システムから電力が供給される複数の負荷機器からなるＩｏＴシステムのシステム構成が変更になり、出力端子数や各出力端子の電圧、電力のＯＮ／ＯＦＦ制御タイミング、電源として接続される電池等の変更が必要な場合においても、ハードウェアの改変の必要がない電源システムを提供する。【解決手段】外部出力端子１１１〜１１４に割り当てる電圧情報、外部出力端子１１１〜１１４のＯＮ／ＯＦＦ情報および切替えタイミング、切替え方法を格納した各情報格納部１２２〜１２４の情報をもとに電源システム制御部１３０が、外部出力端子１１１〜１１４の電圧、ＯＮ／ＯＦＦの切替えを行うとともに、電圧が異なる電池１４１〜１４３を電源とした場合においても、電源情報格納部１２１に、電池の電圧情報を格納することにより、電源システムのハードウェアの変更なしに電池残量、劣化状態を測定することができる。【選択図】図１
