  • Publication number: 20250076401
    Abstract: A battery management apparatus includes a control circuit configured to determine an internal resistance value for each of one or more battery cells included in a battery pack by using a current change amount of the battery pack and a voltage change amount of the one or more battery cells, and diagnose defects in the one or more battery cells by using internal resistance values of the one or more battery cells, in response to charging the battery pack, where the control circuit is configured to determine the current change amount of the battery pack and the voltage change amount of the one or more battery cells based on a current change request time point requiring a charging current change based on a voltage of the battery pack reaching a predetermined voltage during the charge of the battery pack.

  • Publication number: 20210135268
    Abstract: An electrode for an enzymatic biofuel cell may include: a substrate; an electrode positioned on the substrate; and an enzyme pattern containing an enzyme in which a metal-immobilized peptide is expressed positioned on the electrode. The metal-immobilized peptide expressed at the enzyme active site strongly binds to metal deposited electrode surface. In this manner, the enzyme active site facing to electrode was controlled to be in close proximity such that electron transfer efficiency of the electrode can improve.
