The battery management integrated circuit further includes a top input directly electrically connected to a positive output of the battery and configured to receive power from the battery that is defined by a current having a magnitude that is at least an order of magnitude greater than current received by the inputs and a voltage equal to a sum of voltages of all the cells. The battery management integrated circuit is configured to calculate a voltage difference between one of the inputs and an adjacent one of the inputs to determine a voltage of a top cell of the battery cells and to correct the voltage of the top cell to form a corrected voltage as a sum of the voltage of the top cell and a calculated voltage drop across the fuse in the electrical path between the top cell and the one of the inputs. The vehicle further has a controller programmed to balance the cells according to the corrected voltage of the top cell."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Automotive battery system control according to corrected top cell voltage","description":"A vehicle has a battery including a plurality of cells connected in series, and a battery management integrated circuit including a plurality of inputs each being directly electrically connected to a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11489346","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.
