Abstract
Systems of an electrical vehicle and the operations thereof are provided. High-voltage interlock (HVIL) determines if a high-voltage system, such as a power source (e.g., vehicle battery), a load (e.g., vehicle motor), and conductors therebetween, have been properly connected. If not, battery contactor is not allowed to be closed or, if already closed, opened. A redundant HVIL system is provided to mitigate the false positives associated with an HVIL component failure.
