Abstract
An energy store device, especially for a motor vehicle, includes at least two energy sources, which are connected via an electrical connection, and at least one safety element, the safety element being deformable and/or expandable in order to sever the electrical connection between the energy sources. In a method for severing electrical connections of an energy store device having at least two energy sources, a short-circuit risk is determined with the aid of at least one determination device, a propellant is activated following a determination result of the determination device, and at least one safety element is deformed and/or expanded by the activation of the propellant, in order to sever at least one electrical connection of the energy store device.
