High-voltage on-board electrical system and method for operating a high-voltage on-board electrical system

摘要

High-voltage on-board electrical system comprising a high-voltage battery connection with a high-side connection contact and a low-side connection contact, and a high-voltage output with a high-side output contact and a low-side output contact. For safe disconnection of a short-circuit current using levitation, at least one series circuit consisting of a first switching relay and a pyrotechnic disconnecting device is provided between the low-side terminal contact and the low-side output contact.
