Grayson Brulte: You're going to standardize
NACS. What does that process
look like? How will you take what Tesla
built with the NACS and standardize it for
across the industry for use?
Dr. Rodney McGee: Typically, a lot of
standards start off at the very conceptual
stage where experts basically say, how
do we want this to work? And so you
literally start with a blank piece of paper
and then you get some proposals and
then, in, you basically, coalesce on a single
sort of solution. That process typically
takes some time because, you're
creating something where there was
nothing before - or there were things
before, but they were different, had different
requirements.
The NACS standardization process is a
bit different: Today that connector represents
both a majority of use in full EV
and also a [large] market share in
charging stations, especially DC [fast]charging
stations. So, what we're going be
doing in the standards is really capturing

the existing mechanical connector to
make sure that when other manufacturers
want to be interoperable with it, they
have a standard to follow that will ensure
that things work well.
Brulte: The J3400 Standard covers only
the connector, not other aspects of the
charging process?
Christian Thiele: The J3400 is just focused
on the charger unit - the fixture
itself. We have other standards that are
working for the interoperability point of
view, the communication point of view.
The standards back in the day were always
focused just on the vehicle; the vehicle
was a standalone entity. Now there
are communication protocols
that are
Working with Portland General Electric, Daimler Trucks North America (DTNA) in 2021 opened the 'Electric Island' site with eight charging
stations suitable for electric cars, buses, box vans, and semi-trucks. Such stations could accommodate the CharIN Megawatt Charging System
(MCS) standard, which complies with the SAE J1772-based combined charging system (CCS), and is focused on Class 6-8 commercial vehicles
with large battery and packs and the ability to accept a >1 MW charge rate. (Image: DTNA)
