In various embodiments, EIS testing of the battery may be conducted using various test waveforms, such as test waveforms with different voltages, currents, and/or frequencies, to identify and/or predict battery subcomponent and/or interface failures. In various embodiments, EIS testing of the battery may be used to determine when battery conditions are suitable for charging."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery analysis via electrochemical impedance spectroscopy apparatus (EISA) measurements","description":"Electrochemical impedance spectroscopy (EIS) may be used to measure the internal components of a battery or interfaces between connections inside a battery in order to determine a state of one or more","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11502340","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.
