Abstract
Disclosed is a method for determining the ageing (SoH) of a battery (1, 2), such as a lead battery, a nickel metal hydride battery, a lithium ion battery or a capacitor for a vehicle. Several parameters (5.1 to 5.n) of the battery (1, 2) are detected or determined and two parameters (5.1 to 5.n) are predefined as a pair of parameters (5.1 to 5.n, 5.1 to 5.n) and are correlated in such a way that the parameter ranges that form the basis of each parameter (5.1 to 5.n) and value pairs (X1, Y1 to Xn, Ym) of the predefined pair of parameters (5.1 to 5.n, 5.1 to 5.n) that result from said ranges are weighted in classes.
