The method includes: setting a test discharge current (I4d) and a test end voltage (Vend) for the rechargeable battery (4) to be used during the test; at a first point in time (T0), starting a test run measuring a current (I4) from the rechargeable battery (4) and a voltage (V4) over the rechargeable battery (4); at a second point in time (Tend), when the V4 becomes equal to the Vend, terminating the test run; and registering the time period elapsed between T0 and Tend as a measure of the status of the rechargeable battery (4)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and system for testing a rechargeable battery","description":"A method of testing a rechargeable battery (4) connected to a DC bus (5) of a converter (11) of a power supply system (10) including a control system (12) for controlling power transfer between a powe","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11249140","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.
