In the case of executing the cell abnormality determination process during the equalization process, the controller provides the detected voltage of a target cell to be subjected to the equalization process with a compensation value corresponding to a voltage change based on energy transfer in the target cell due to the equalization process between the first time and the second time, and calculates the voltage difference at the second time."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Management device and power supply system","description":"A controller executes an equalization process of equalizing capacities of a plurality of cells, and a cell abnormality determination process of, of detected voltages of the plurality of cells, calcula","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11949257","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.
