  "textContent": "The battery degradation detection device includes an impedance measurement unit and a degradation detection unit. The impedance measurement unit measures impedances of a battery at a plurality of frequencies. The impedance for at least one of the plurality of frequencies, measured by the impedance measurement unit, has a positive imaginary component. The degradation detection unit detects degradation of the battery on the basis of real components of the impedances at the plurality of frequencies detected by the impedance measurement unit.",
