Abstract
High-voltage vehicle electrical system comprising a high-voltage battery terminal having a high-side terminal contact and a low-side terminal contact and a high-voltage output having a high-side output contact and a low-side output contact. For reliable isolation of a short-circuit current by using levitation, at least one series circuit arranged between the low-side terminal contact and the low-side output contact and consisting of a first switching relay and a pyrotechnic isolating device is provided.
