The battery management system includes a control unit that transmits an open cell detection signal, to enable a balance unit for a first time period and to disable it for a second time period, and to enable an under-voltage comparison unit and an over-voltage comparison unit for a third time period. The under-voltage comparison unit compares a voltage with a first open cell threshold and outputs a first comparison result in the third time period. The over-voltage comparison unit compares a voltage with a second open cell threshold and outputs a second comparison result in the third time period. A judging unit determines whether a connection between a first battery unit and the battery management system is inoperative based on the first and second comparison results."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Open cell detection systems and methods","description":"An open cell detection system includes a battery management system.
