The controller turns on the changeover switch to apply a voltage to the capacitor from the second battery, the detection circuit subsequently detects a potential difference or a discharge current, and the diagnostic unit diagnoses at least one of the capacitor, a lowermost first switch, and the second switch."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Diagnostic apparatus and diagnostic method","description":"A diagnostic apparatus includes a capacitor capable of being connected in parallel with a first battery, first switches that switch the connection state between a plurality of the first batteries and ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11307256","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
