The system is configured to control the current source to drive the battery with a current cycling profile, and to measure current signals between anode and cathode, and voltage signals derived from the voltage meters. An impulse response is then calculated for each of the anode and cathode, to dynamically estimate open-circuit potential and impedance of each of the anode and cathode. Battery aging, battery capacity fading, and other diagnostics are provided in real time. This invention can characterize each individual electrode of a battery, even when the battery is cycling away from equilibrium states, which is important for electric vehicles."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and apparatus for real-time characterization of batteries with a reference electrode","description":"The disclosed battery system comprises a three-electrode metal-ion battery configured with voltage meters connected between anode and cathode, between anode and a reference electrode, and between cath","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9847558","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.
