8. A pyrotechnical disconnection unit for at least impairing an electrical coupling at an electrical energy supply, comprising: an electrically conductive connection section via which the electrical energy is conductible from the energy supply, a housing, in which the connection section is arranged, and a pyrotechnical substance accommodated in the housing in direct contact with an inner side of a base of the housing and arranged adjacent to a heat source, which is a characteristic for a critical operational state, the pyrotechnical substance being designed and/or controllable in such a way that its pyrotechnical effect is unfolded when reaching a predefined operational state, wherein the pyrotechnical substance is attributed to the connection section in such a way that thermal energy from the pyrotechnical effect of the pyrotechnical substance directly effectuates complete disintegration of at least a portion of the connection section, thereby at least directly limiting the electrical conductivity of the connection section inside the housing.
