Abstract
A method for determining the amount of charge which can be drawn from a storage battery includes determining a response signal profile within a time interval to an electrical stimulus to the storage battery. The method also includes linearizing the response signal profile and determining the amount of charge which can be drawn as a function of a degree of change of the linearized response signal profile in the time interval. A monitoring device for a storage battery is provided that includes measurement means for measuring at least one of voltage and current of the storage battery over time intervals. The monitoring device also includes evaluations means that are designed for carrying out the method.
