Abstract
A method for determining the charge state of a battery in a motor vehicle includes steps of applying a measuring voltage to a coil, cyclically reversing the polarity of the measuring voltage if the absolute value of the secondary current flowing through the coil exceeds a predetermined threshold value, scanning the secondary current, reconstructing the curve of the secondary current based on the scanned secondary current values, and determining the charge state based on the curve of the secondary current values.
