Each sub-circuit includes voltage dividing resistors, a reference voltage generator, and a comparator. The voltage dividing resistors generate a voltage division signal by dividing an output voltage of the battery cell. The reference voltage generator generates a reference voltage. The comparator compares the voltage division signal against the reference voltage. Each comparator is powered with voltage across the battery cell associated with the sub-circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Protection device for secondary batteries, and battery pack and electronic equipment employing same","description":"A protection device includes a voltage detector having N or more sub-circuits each for monitoring a specific battery cell to output a detection signal when at least one of the battery cells outputs an","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8471526","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.
