  • Publication number: 20220373602
    Abstract: In a battery measurement apparatus, a signal control unit, provided on a first electrical path connecting electrodes of a storage battery, causes the storage battery to output a predetermined alternating-current signal or inputs a predetermined alternating-current signal to the storage battery. A response signal input unit, provided on a second electrical path connecting the electrodes, inputs a response signal of the storage battery in response to the alternating-current signal through the second electrical path. Based on the response signal, a calculating unit calculates information related to a complex impedance of the storage battery. A magnetic flux passage area, surrounded by the storage battery and the second electrical path, is formed. A size of the magnetic flux passage area is set such that an error between an actual complex impedance of the storage battery and a complex impedance calculated by the calculating unit is within a range of ±1 m?.

  • Publication number: 20210018570
    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.
