Contamination avoidance combination high voltage interlock cover

摘要

The present disclosure is directed towards a high voltage interface cover system for inhibiting liquid contamination of high voltage connection areas of EV's and HEV's. This liquid contamination may come from atmospheric precipitation or road splash which comes in contact with the surface of either the HVDC connection block cover and/or the high voltage main device cover, and flows into the interface seals connecting them. The cover system comprises a pair of interlocking covers which provide a tortuous path for liquid contamination to penetrate the interface.

主权项

1. A cover system for high voltage electric vehicle and hybrid electric vehicle applications comprising;
a high voltage connection block; a high voltage device comprising a separate component from the high voltage connection block, but spaced from the connection block a predetermined distance and connected to the connection block by an interface, distal from a top opening of the high voltage connection block and a top opening of the high voltage device creating an exterior space between the interface and the top opening of the high voltage connection block and the top of the high voltage device, the high voltage device being selected from the list including a traction inverter, DCDC converter, and onboard charge module; a first cover, for covering the top opening of the high voltage connection block; a second cover for covering the top opening of the high voltage device, the second cover being relatively planar but having a raised edge along the side proximal the connection block, wherein the first cover partially overlaps the second cover raised edge and the exterior space when installed in a vehicle.
