Effects of Communication Protocol on Bolt EV Charging Efficiency

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.

I thought in the US the Tesla supercharger connector was a modified version of the SAE Type 2 plug and in Europe the standard Type 2 Mennekes plug.

In any event, I can't see why a communication protocol would affect charging efficiency. It's just signaling.
