Pyrotechnical Disconnection Unit, System for Electrically Charging an Electric Energy Cell, Mobile Device and Charging Device

摘要

The pyrotechnical disconnection unit for impairing, preferably interrupting, an electrical charge coupling between a chargeable electrical energy cell, particularly comprising an electrical energy storage and an energy converter, and an electrical energy supply, such as a charging device, provides an electrically conductive connection section, such as an electrically conductive cable, an electrically conductive path or such, via which electrical charging energy is supplied from the energy supply of the electrical energy cell, a housing, in which the connection section is arranged, and a pyrotechnical means accommodated inside the housing being designed and/or being controllable in such a way that it unfolds its pyrotechnical effect when reaching a predefined operational state, wherein the pyrotechnical means is attributed to the connection section in such a way that the pyrotechnical effect of the pyrotechnical means at least limits, preferably suspends, the electrical conductivity of the connection section inside the housing.
