Local high voltage safety interlock for HV components in a vehicle with feedback to the vehicle system

摘要

A high voltage (HV) safety lock for HV components in a vehicle has an HV plug, including a safety bridge arranged in the HV plug and connected to a central vehicle control via an internal bus system within the vehicle or a simple switched signal via a decentral control and regulating unit of an HV component. The safety bridge is connected to an LV power supply configured with electric isolation from the HV system.
