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.

A method for detecting a state of an electrical connection of a battery to a vehicle's electrical system, comprising:
- recording, in an approximately synchronous manner, operating variables including a battery current and a generator current of a generator coupled to the electrical system;
- and
- ascertaining the value of the battery current when a change occurs in the generator current of the generator during a specified transitional period, whereby a compensating effect of the battery current in the form of one of a current supply and a current consumption is ascertained;
- wherein the transitional period is equivalent to a characteristic time constant of the generator and a controller associated with the generator.

- and
- ascertaining a value of the battery current when a change occurs in the generator current of the generator during a specified transitional period, whereby a compensating effect of the battery current in the form of one of a current supply and a current consumption is ascertained;
- wherein, if the generator current is changed by a predetermined current amount during a predetermined time span, an analysis of the battery current during the specified transitional period is made.
