Abstract
A high voltage wiring system for an electric powertrain is disclosed. The system includes a power conversion unit sealed in a first enclosure. The system also includes at least one second enclosure configured to be sealed and having at least one cable disposed therein. The disclosed system further includes a plurality of wiring termination compartments configured to provide a plurality of electrical termination points. The plurality of wiring termination compartments are separately encased in a material configured to provide a sealed barrier between an outside environment and the plurality of electrical termination points. The disclosed system further includes a source of at least one pressurized gas configured to substantially prevent the ingress of moisture into the first enclosure, the at least one second enclosure, and the plurality of wiring termination compartments.
