Methods for monitoring the state of charge of a battery of a motor vehicle are disclosed in which the battery current is determined at moments at which the battery charging voltage has decreased to a defined limit value. The battery current thus determined is transmitted to an evaluation unit, which generates an alarm signal if no discharge of the battery is measured by means of the determined battery current in a defined period. The limit value for the decrease of the battery charging voltage is selected such that the algorithm as a result can identify whether the state of charge of a battery lies above or below a threshold above which a certain electrical functionality of the battery can be guaranteed.
