The battery management system double-checks whether the pre-charging of the capacitor is completed based on a voltage across the capacitor and a voltage across the main contactor. The battery management system keeps a contact of the main contactor in an open operational position when the voltage across the capacitor is less than a first threshold voltage or the voltage across the main contactor is equal to or higher than a second threshold voltage."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery management system, battery pack and electric vehicle","description":"A battery management system protects a main contactor from inrush currents, wherein the main contactor opens and closes a charge/discharge path connected between a first battery and an electrical load","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11271412","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.
