The truth about Electrify America's progress and Traveling with the Mach E

[ChasingCoral]

Tesla’s is purpose built, that’s for sure.

CCS was the industry basically saying “well, we already have this plug, let’s just bolt some DC contacts below it. That’s okay - it works, but it’s not great - makes it unnecessarily large versus a design which carries power over the same contacts whether AC or DC.

Plus, it is very annoying we have to have CCS1 and CCS2 with different configurations for NA and EU.

Though that was the baseline: menekes in the EU and SAE J1772 in the US. It was a zero sum game from that perspective, whereas they could have harmonized.

The main thing I scratch my head about is: what was the point of making a Frankenplug which keeps Menekes and J1772? Is it so people who already have them don’t need to use an adapter or use a new charger for level 1-2 with future cars?

It seems very short-sighted. What if the multimedia industry decided to add 7+1 audio jacks to a digital video connector instead of rolling out the very compact HDMI?

The advantage is backward's compatibility. Maybe they were afraid if everyone had to have new plugs it would delay EV market penetration.

Seems shortsighted, though. The more vehicles they build, the more cemented the bandaid design becomes. Companies could have included for free both home charging cables and adapters to menekes or j1772 (like Tesla did, which puts to bed any notion they are trying to hold owners hostage to their network).

also I suspect delaying market penetration was a goal...

VHS vs Betamax all over again.

I also think that the J-1772 connector is future proof to in the sense that I think you will be able to do C2G (car to grid) via your J-1772 and compatible home charger, or use your car has an emergency power source like the Chademo can with an invertor at this moment(converting DC to AC), but I'm not sure about the Tesla connector.

Was over at Northgate mall's Bed, Bath & Beyond yesterday for a curbside pickup and saw a lady charging this beauty at 150kW. Not a Mach-E but man, sexy nonetheless!

I guess that is part of "Beyond".

I thought only CHAdeMO had V2G at this point, not J-1772 or Mennekes. Did I miss something?

Nothing is “future proofed.” Eventually vehicles will come along which need or can make use of higher power, and the charging infrastructure will evolve, independent of the connector interface. At best it is “today proofed.”

Not at this time but they are working on a standard to come and I believe J-1772 will be compatible with that.

Edit: I thought that is what I meant in my post, sorry if I didn't explain it correctly.

Yes but at least right now J-1772 can go has high has 350kW, so it can go a long way.

J-1772 can go to 19kW, I believe. 350kW requires the dedicated DC contacts of CCS.

Yes I think you're right, the only connector used when connected to a DCFC for the J-1772 part of the connector is the one pin that makes the hand shake with the vehicle.
