The battery backup system further comprises a power supply configured to convert the source voltage to a charging voltage and control circuitry electrically coupled to the power supply and the battery and configured to communicate the charging voltage to the battery to facilitate charging the battery when the source voltage is available. The control circuitry is configured to measure one or more parameters of the battery to evaluate battery health. When the battery polarity is reversed, battery terminals through which the battery is electrically coupled are shorted to one another, or the battery is removed, the control circuitry is configured to decouple the charging voltage from the battery."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Fault-tolerant battery management system and method","description":"A battery backup system comprises an input terminal configured to receive a source voltage from a power source, and an output terminal electrically coupled to the input terminal and a battery and conf","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11527911","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.
