Based on a predetermined amount of an infinitesimal change in the parameter and an evaluation function that is obtained using a result of the comparison, the calculating portion numerically calculates a slope of the evaluation function and renews the parameter based on the slope. As a result, the secondary battery control unit has the calculating portion capable of identifying the parameter of the equivalent circuit while reflecting effects of deterioration of the secondary battery and capable of being integrated to a vehicle-mounted microcomputer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Secondary battery control unit","description":"A secondary battery control unit has a calculating portion identifying a parameter of an equivalent circuit based on an estimation error that is obtained by a comparison between an actual output value","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9827868","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.
