Abstract
A waveform designator designates a given waveform of an AC signal by specifying a frequency as a reference. A signal controller causes a storage battery to output a response signal based on its own power. A detector detects a frequency component in the response signal corresponding to the reference frequency of the AC signal based on a product of the reference frequency and the response signal. A calculator calculates a complex impedance of the storage battery based on the frequency component in the response signal. A noise determiner determines presence or absence of a noise signal corresponding to the reference frequency of the AC signal before the signal controller causes the storage battery to output the AC signal. A noise controller either avoids or removes the noise signal.
