Someone was kind enough to point out to me that Tesla and CHAdeMO equipped cars actually use a different communication protocol than the Bolt EV (CAN bus versus IEEE.1901 respectively).
My question is, could that affect charging efficiency? I know that CAN has to run through the car's ECU, but I'm not sure whether that would add additional parasitic losses. This question is probably more loaded and involved than I think, but I thought I'd ask anyway.
*I just noticed that we actually have a dedicated "Charging" forum. Please move this post if that is more appropriate.
