In the freezing determination, the freezing determination section executes freezing determination current control for supplying a current at a freezing determination current value at a freezing determination time in a direction to charge the non-aqueous electrolyte secondary battery. When a voltage value output from the battery voltage output section exhibits a transition that rises once to a peak value during execution of the freezing determination current control, and then decreases with time, it is determined that the non-aqueous electrolyte is in a frozen state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Non-aqueous electrolyte secondary battery system","description":"A non-aqueous electrolyte battery system includes a battery voltage output section for outputting a voltage of a non-aqueous electrolyte secondary battery and a freezing determination section for perf","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9728819","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.
