In one embodiment, measurement circuitry measures a first terminal voltage at a time immediately prior to or at a beginning of the first pulse of the calibration packet, and a second terminal voltage, in response to the calibration packet, at a time during the partial relaxation time period of a battery. Control circuitry determines a partial relaxation time voltage (VPRT) at the battery's first SOC using the first and second terminal voltages and determines a temperature of the battery by correlating the VPRT at the first SOC to a temperature of the battery at the battery's current SOH."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and circuitry to determine temperature and/or state of health of a battery/cell","description":"Techniques and circuitry, in one embodiment, determine a temperature of a battery by applying a calibration packet to the battery's terminals and at the battery's first SOC, wherein the calibration pa","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9726554","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.
