PROBLEM TO BE SOLVED: To provide a power supply device system that protects a power storage device on the basis of information of power restrictions or the like. SOLUTION: The power supply device system 10 includes: a power storage device 12 connected to a load circuit; a limit-value detecting means for detecting a limit value that limits input/output power with respect to the power-storage device 12; a current-value acquiring means for acquiring a current value flowing to the power storage device 12; and a relay circuit part that is provided between the power storage device 12 and the load circuit so as to switch the power storage device 12 and the load circuit to a connected state or a disconnected state. When a value detected by the limit-value detecting means is a prescribed value and a current value acquired by the current-value acquiring means exceeds a threshold continuously for a prescribed period of time, the relay circuit part puts the power storage device 12 and a load circuit in the disconnected state.
