摘要： The present invention relates to a method for determining the state of charge of a vehicle battery (150) of a vehicle, a starter relay of a starting device (100) for an internal combustion engine of the vehicle for engaging a starter pinion in a ring gear of the internal combustion engine having a first winding (121) and a second winding (122) which can be controlled independently of one another, the first winding (121) being controlled in predetermined control states and voltage values that are established in the course of these control states being determined and the state of charge of the vehicle battery (150) being determined depending on the determined voltage values.
