Abstract
A device and a method for detecting a missing electrical connection of an energy store to an energy-supply system, particularly an electrical system of a motor vehicle, in which at least one current-sensing device senses at least one current flowing in the energy-supply system or energy store, at least one dispersion of the current being determined and compared to at least one threshold value in order to detect a missing electrical connection of the energy store to the energy-supply system.

1-11. (canceled)
A method for detecting a missing electrical connection of an energy store to an energy-supply system, the energy-supply system being an electrical system of a motor vehicle, the method comprising:
- sensing, by at least one current-sensing device, at least one electrical current flowing in the energy-supply system or energy store;
- determining at least one dispersion of the current;
- comparing the determined dispersion to at least one threshold value;
- and
- detecting a missing electrical connection of the energy store to the energy-supply system, based on the comparison.
A device for detecting a missing electrical connection of an energy store to an energy-supply system, the electrical-supply system being an electrical system of a motor vehicle, the device comprising:
- at least one current-sensing device configured to sense at least one electrical current flowing in the energy-supply system or the energy store;
- and
- at least one processing unit configured to determine a dispersion of the current, to compare the determined dispersion of the current to at least one threshold value, and to detect a missing electrical connection of the energy store to the energy-supply system.
