Claim 5:
6. The backup power-supply system according to claim 4, wherein
a load out of the plurality of loads other than the particular load is defined as a non-particular load,
an amount of a drop of the output voltage at a start-up of an operation of the particular load is defined a voltage-drop amount,
an amount of a return of the output voltage of the power storage unit at an end of an operation of the non-particular load is defined as a voltage-return amount, and
the threshold voltage is determined based on a voltage difference obtained by subtracting the voltage-return amount for the non-particular load from the voltage-drop amount for the particular load.
