  • Patent number: 12181534
    Abstract: A method and a device for testing a battery state determines if a battery is faulty. A first impedance test is conducted to determine the internal resistance of the battery, wherein the battery is energized with an electrical current flow with a certain frequency and a resulting voltage response of the battery is measured. A load high-current test of the battery with a test pulse HRD test is conducted next. Then, a second impedance test is conducted. The measurement results of the tests are recorded and stored, and then evaluated by arranging such results offset in relation to one another, in such a way that the battery state can be derived therefrom, in particular whether the battery is faulty.
