Abstract
The invention relates to a method for determining a current state of charge value (SOC, SOC, SOC) of a battery of a specific battery type, wherein a field of characteristic curves is provided, which, for certain different predetermined temperature ranges (ΔT), specifies an internal resistance (Ri) for the specific battery type in dependence on the state of charge (SOC) for the specific battery type, a current temperature (T) of the battery is measured, a current internal resistance value (Ri, Ri) of the battery is determined, and, on the basis of the current temperature (T) and the current internal resistance value (Ri, Ri), the current state of charge value (SOC, SOC, SOC) of the battery is determined by means of the field of characteristic curves.
