Abstract
A method for detecting the state of electrical connection of an energy store, e.g., a battery, to a vehicle's electrical system includes ascertaining operating variables, e.g., battery current IB and generator current IG, essentially in time synchronous fashion. When there is a change in the generator current IG of the generator during a transitional time, the energy store is checked for the value of the battery current IB for the detection of a compensating effect in the form of a current delivery or a current consumption.
