Abstract
A secondary battery system includes a secondary battery having an electrode body impregnated with an electrolytic solution containing metal ions. The secondary battery system measures an impedance of the secondary battery. The secondary battery system detects high-rate deterioration caused by uneven concentration of the metal ions in the electrolytic solution impregnated into the electrode body.
