The protection circuit turns off the first switch device and the third switch device when an overdischarge of the secondary battery is detected."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery pack","description":"A battery pack has a secondary battery, first and second switch devices provided between the secondary battery and a load or a charging unit, a protection circuit detecting an overcharge, an overdisch","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8524385","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.
