I’ve not studied the technologies, but it seems to me this is mostly about
Ford/GM looking to provide a better charging experience for their customers. It
reminds me of the VHS vs. Beta competition in the late 70’s. From everything
I’ve read, the Supercharger network provides a better experience than the
competition. Once other auto manufacturers can leverage this network to provide
a similar experience, that should accelerate the adoption of all EV’s. I think
Tesla owners are worried that this will result in long lines at the
Superchargers. My hope is that the Supercharger network can meet the increased
demand. And hopefully other charging networks can help by offering a similar
charging experience. We recently stopped at the Bucky’s in Crossville and that
was amazing.

Rob,

As it is, standards wise, the CCS1 connector in the US is included in the SAE
J1772 specification. That specification, even by its’ title, is “recommended
practice”, and they have been stupid slow to update it over the years. CCS
signaling is now being included in superchargers- although for NACS they use
DIN 70121 and plug and charge per ISO 15118.

I agree there needs to be a standard, but the US government doesn’t seem
interested in dictating any one thing which has been IMO both good and bad -
good in that Tesla was able to go off on their own when the specs didn’t meet
their needs for both L2 and DC fast charging, and bad in that we now have a
mess of J1772 L2, J3068 L2, CCS1, CCS2, CHAdeMO, and NACS in the US.

If you’ve not read through the standard, it’s worth a read.

Also, one other thing about NACS vs J1772/3068/CCS is *anyone* can go read the
spec, instead of having to pay a Fee for the privilege.

While I do agree that for the success of the EV market there needs to be one
uniform charger port, there just isn’t enough DC chargers, I’m not a fan of
NACS platform. There needs to be a set IEEE standard put in place that the
industry adheres itself too, if not with the constant change it will be
confusing and it will create less options. There is a reason that the end of a
gas pump has been the same since the 1940s. By letting the market create
multiple private platform connectors it won’t be stable. Just my two cents, ha.

I was shocked by the news just over a week ago that Ford was moving to the
NACS port but now that GM has done it as well, has left me gobsmacked. I never
would have thought that either of these companies would ever latch on to the
Tesla network. Being a Bolt and Spark owner I am thrilled to have access in the
near future to all of the charging networks (sorry about our 50 kW max). More
options is better for us all. This should help to build out the charging
network and make it ubiquitous, which will simplify the transition to EV for
all the people nervous about switching from ICE to EV. Looking forward to
figuring out how to park at Tesla Supercharger with the charging port on the
wrong side/end of the car.
Thanks for sharing Marty!!
