  • Patent number: 12044742
    Abstract: A battery management system includes a displacement sensor configured to detect a displacement of a cell group including a plurality of battery cells connected in parallel, and a control unit. The control unit is configured to record the displacement of the cell group at a predetermined time interval for a first diagnosis period from a first time point to a second time point during charging of the cell group. The control unit is configured to determine a first displacement curve from a history of the displacement over the first diagnosis period. The control unit is configured to determine whether the plurality of battery cells is nonuniformly degraded based on the first displacement curve.

  • Patent number: 11628164
    Abstract: Salsolinol is a metabolite of alcohol and is cytotoxic, so that the salsolinol has been studied as a diagnostic biomarker for a liver disease and a liver cancer, but the salsolinol has not been reported as a therapeutic agent for the liver disease or the liver cancer. Since the salsolinol regulates tumor-related genes and inflammation-related genes specifically for men, it is experimentally found that the salsolinol has an effect of alleviating a liver cancer and an alcoholic hepatitis. Therefore, the salsolinol is contained together with a pharmaceutically acceptable salt as an effective ingredient and is provided as a pharmaceutical composition for treating the liver cancer or a health functional food for preventing and improving the alcoholic liver disease to have an effect of treating the liver disease and the liver cancer or preventing and improving the liver disease and the liver cancer.
