The estimation apparatus estimates the internal state of the energy storage device by using a voltage value and an energization amount in a predetermined voltage range of the energy storage device or at a predetermined measured voltage value, or based on information on the shape of a discharge curve of the energy storage device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Estimation apparatus, estimation method, and computer program","description":"An estimation apparatus estimates an internal state of an energy storage device having a positive electrode, a negative electrode including a negative active material that contains SiOx, and a nonaque","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11480619","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.
