Abstract:
A deterioration state detection apparatus for detecting a deterioration state of capacity enabling charge or discharge of a nonaqueous electrolyte secondary battery includes: an acquisition unit that acquires a capacitance of the nonaqueous electrolyte secondary battery: and a determination unit that determines the deterioration state of capacity enabling charge or discharge of the nonaqueous electrolyte secondary battery, from change of the acquired capacitance.
