The way that I see shielded power cables being grounded to chassis is at a point of feed-through there is a clamp across the shield (outer insulator removed at that point) to both mechanically secure the cable as well as providing electrical contact to ground. I have seen this done with the HV cable pair in the Prius where it goes from the battery in the trunk that has two contacts on its shell that line up with a cutout in the trunk separating sheet metal and immediately next to that cutout is a blank metal space where the two power cables are routed and clamped down and grounded. The cutout is then covered by a metal cover behind the back seat. Any point along the cable can be used for grounding using a clamp, though preferably not in areas where water can access the cable to avoid corrosion and loss of contact. Note that this grounding is typically done in *one* spot only, to avoid ground loops. So, find a weather-protected spot along the cables where the chassis is conveniently close and preferably where you need to mount the cable anyway and scrape the chassis clean to clamp the cables against it or use a stand-off clamp that you screw to the chassis for ground and mechanical support and clamp the cables with.

However, because we are doing the vehicle for a SAE Design competition, if we use shielded HV cable then we do not need to put into conduit. We need to ground the shield to the chassis. I thought there would be some sort of connector for that. On Wed, Feb 3, 2016 at 4:34 PM, Cor van de Water via EV <[email protected]> wrote: > Ah, that is quite a different beast.
