Publication number: 20250309635Abstract: An electronic power distributor arrangement for a vehicle on-board network having at least one load path emanating from an on-board battery, which splits into at least one or more load channels to each of which electrical consumers are connected. Each of the load channels is subdivided into a conductor path applied onto a circuit board, and a supply line leading to the consumer. The load path includes a switch unit that switches off the load path in the event of a thermal overload of one of the supply lines. An evaluation device is assigned with the switch unit, and the evaluation device is to determine a thermal overload of one of the supply lines based on the conductor path temperatures of the conductor paths.Type: ApplicationFiled: March 26, 2025Publication date: October 2, 2025Applicant: Lisa Dräxlmaier GmbHInventor: Michael WORTBERG
