The present invention relates to a method for providing a predetermined pyrotechnic energy output to a pyrotechnic separating device for separating an electrical line, such as a cable, a wire, a conductor path or the like, leading to an electrical energy source, such as a battery or an accumulator, for outputting and/or receiving electrical energy, in which: a temperature of or in the vicinity of the electrical energy source is detected; and, when the detected temperature exceeds a predetermined temperature threshold, the pyrotechnic separating device is remotely activated to separate the electrical line at a location spatially remote from the electrical energy source.
