Abstract
A vehicle includes a high-voltage (HV) energy storage system (ESS), an HV device having HVIL source and return (SR) pins and an HV receptacle, an HV cable, and an HV terminal assembly. The assembly includes a tray portion and retainer for aligning the HV cables with the HV receptacle. An HVIL jumper device is connected to the tray portion and electrically connectable to the HVIL SR pins. The assembly includes a cover portion removably mountable to the tray portion to provide a suitable EMF shield and weather seal. The cover portion includes an HVIL shorting plug. HV electrical energy is supplied from said ESS to the HV device only when all three of the HVIL components, i.e., the HVIL SR pins, the HVIL jumper device, and the HVIL shorting plug, are electrically interconnected to form a closed HVIL circuit, while at the same time the HV cable is properly connected.
