1. An AC generation circuit attached to a secondary battery, comprising:
a circuit configured to generate an alternating current at both ends of the secondary battery;
a current limiting element connected between a positive electrode side of the circuit and a positive element of the secondary battery and/or between a negative electrode side of the circuit and a negative electrode of the secondary battery; and
a capacitor connected in parallel to the current limiting element,
wherein the circuit includes two or more in-circuit capacitors and generates the alternating current by switching a connection relationship of the two or more in-circuit capacitors in series or in parallel with respect to the secondary battery.
