What makes no sense is trying to use EV's is driving long distances.
Use
the right tool for the job. It makes about as much sense to buy an EV
for
interstate travel as it does to buy a push mower for an acre.
Get a PIH. The idea of electrification of transportation is to stop
burning
away our limited oil supplies just going to and from work and daily
local
travel. Save it for where it is needed most. Aircraft and long
distance
travel. It makes no sense to try to force EV's to go long distances
where
it makes no sense, and then to complain it takes so long to charge a
250
mile battery. The problem is the *wrong* car for the job. Not the
wrong
charger.

What’s The Story With EV Superfast Charging?

One of the top things I criticize conventional automakers about is EV
fast
charging — or lack thereof. Well, since automakers and charging
companies
have adopted the term “fast charging” for rather slow 50 kW charging,
what I
technically push is “superfast charging” (I know, it’s a great
“technical”
term. To match it up with industry terminology a bit more, I’ve also
termed
it Level 4 charging.”) If this is all a bit new to you, here’s a brief
summary of the key points as they stand today:
The fastest non-Tesla EV fast-charging stations out there can charge a
~200-mile electric car like the Chevy Bolt (if it has the capability)
from
0–80% in approximately 1 hour, or 30–80% in approximately 35 minutes.
Driving for a couple of hours, and then charging for an hour, and then
driving for a couple of hours, and then charging for an hour, just
isn’t a
convenient way to take a road trip. The story is probably even less
convenient if you are stopping at shorter intervals to charge due to
charging stations not being widespread enough to be placed exactly
where you
want them.
Tesla Superchargers are up to 120 kW in output capacity, and can thus
charge
a Tesla approximately twice as fast as the fast chargers noted above.

Exciting as it may be, turning a 6-hour road trip into an 18-hour road
trip
isn’t likely to win over many people in the mainstream car market.
Faster CHAdeMO & CCS Charging Standards Compete With Tesla
Supercharging
We’ve gotten word in the past year that the two open fast-charging
standards
(CCS and CHAdeMO) have increased their max rates to 150 kW, CHAdeMO
doing so
as recently as this past month. However, as far as I know, there isn’t
a
single superfast-charging station out there as part of a network
drivers can
use (presuming their cars are even equipped to make use of it), and
there
are no public announcements of companies planning broad
superfast-charging
networks. So, I contacted our good friends at Fastned, a charging
network
leader based in the Netherlands, to see if they had any knowledge on
the
matter that they could share.
The helpful spokeswoman for the company directed me to this recent
article
on the Fastned blog, which has a number of interesting tidbits in it,
and is
a great summary on EV fast charging in general.
First of all, it’s worth pointing out that there’s unlikely to be much
movement on superfast charging until automakers have cars on the market
that
can make use of it, and such cars are in the works. Today, the Kia Soul
EV
is the only non-Tesla electric car that has a charging capacity up to
100 kW
(the max is typically 50 kW), but the fully electric Hyundai Ioniq is
supposed to have the same, and Volkswagen Group (including Volkswagen,
Audi,
and Porsche) has made announcements that make it clear future electric
models should have capability up to or even above 150 kW (the Audi Q6
e-tron
planned for 2018 and the Porsche Mission E planned for ~2020, for
example).
Yes, Volkswagen is particularly popular on vaporware forums, but the
plans
seem legit, so let’s not be too cynical. Still, these cars are years
away,
and there’s no strong sign that the automaker is aiming to bring about
a
genuinely satisfactory superfast-charging network.
Oh yeah, something I don’t recall seeing previously is that the
next-generation Nissan LEAF might be able to use 150 kW CHAdeMO
superfast
charging, but Fastned mentions this in the blog as well. Nissan has
been
heavily involved in rolling out a somewhat decent (depends who you ask)
fast-charging network in the US and Japan, and one would presume that
it
would work hard to upgrade these stations to provide up to 150 kW.
… But Who Will Build The Superfast-Charging Networks?
Even if Volkswagen, Mercedes, BMW, Nissan, etc., are planning
long-range
electric cars with superfast-charging capability, I’m quite skeptical
that
the automakers will work to develop a widespread, well-planned network
that
matches the Tesla Supercharger network. In the past, I’ve pushed
automakers
to simply partner with Tesla (Tesla has welcomed the option with open
arms),
but there’s no sign they want to cede the victory to Tesla on this
matter,
even if it means offering their customers less-than-adequate products.
Of
course, as I wrote the other day, these automakers actually want the
transition to electric cars to happen slowly, so this comes as no big
surprise.
Fastned and the free market to the rescue? The remaining option is that
outside companies will build the convenient, superfast charging
networks
customers desire. This is a daunting task, as capital expenditures for
these
high-power charging stations are not at all small, and siting +
permitting
are also huge challenges. I know many people think that there isn’t a
strong
financial business case for such an effort. However, Fastned is in this
game
for the long haul, and it is doing great work to help enable our
electric
future. From the blog:
“Many Fastned stations are already prepared for 150 kW chargers. We
have
grid connections that support charging four cars simultaneously at 150
kW.
Our other stations can easily be upgraded with a larger grid connection
as
well. More capacity can be added in the future by introducing on-site
battery buffering and/or by further increasing the capacity of the grid
connections. The layout of our stations is already designed for maximum
throughput of cars.”
Of course, timing is key here. As I said, these are huge investments.
You
don’t want to put the cash forward 3 years before it’s useful. Also,
you
need the actual chargers to be available (I’m sure companies like ABB
are
working on this, but I have no idea how far they are from having a
product
on the market). On these matters, Fastned adds:
“We expect to install the first 150 kW chargers at Fastned stations in
2017,
depending on introductions of cars with 150 kW capability by the car
makers
and the availability of these high powered chargers.”
So, there’s Fastned, which is based in the Netherlands and expanding
into
Germany and maybe other countries in Western Europe. But what about the
USA?
What I’ve heard so far on the matter is … crickets singing.
The fast-charging networks for non-Tesla cars are already criticized
quite a
lot for the charging stations not being placed in the most convenient
locations for long-distance travel (like, on dealership lots far off of
the
Interstate that are locked up at night) and for pretty bad reliability,
meaning that you can’t be that sure a charging station you go to use
will
actually be in service ...
