Abstract
A method for checking a battery state for at least one battery of at least one motor vehicle. A. determination of cell voltage differences of particular cell voltage values of at least two battery cells of the at least one battery at different points in time. B. comparison of the cell voltage differences with at least one predetermined cell voltage reference value assigned to the at least two battery cells, and determination of respective deviation values between the cell voltage differences and the at least one cell voltage reference value. C. determination of the battery state of the at least one battery, wherein, based on the particular deviation values, it is determined whether an inadmissible degradation of the battery state is imminent.
