An auxiliary power supply device includes a storage circuit having first and second electrical double layer capacitors connected in series between first and second nodes, a first switch element having a first terminal coupled to the first node, and a second terminal, a first discharging resistor provided between the second terminal and a fourth node, a second discharging resistor provided between the fourth node and ground, a second switch element having a third terminal coupled to a third node between the first and second electrical double layer capacitors, and a fourth terminal coupled to the fourth node, and a measurement controller. The measurement controller performs a procedure to compute a capacitance value of the storage circuit as a first process, and a procedure to connect the first switch element and connect the second switch element as a second process.
