The control device acquires an electricity storage amount that is the amount of electricity stored in the secondary battery, and V/K indicating the magnitude of change in OCV of the secondary battery with respect to temperature change of the secondary battery. The control device determines whether or not an SOC unevenness occurs in an electrode surface of the secondary battery by using the acquired electricity storage amount and V/K."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Diagnostic apparatus for secondary battery and SOC unevenness detection method","description":"A diagnostic apparatus for a secondary battery includes a control device.
