CCS Electric Car DC Quick Charging Trails CHAdeMO By Two Years in
California

CCS is lagging behind CHAdeMO in charging station deployment in a big
way

CHAdeMO is more common in California than CCS

As PlugShare’s data shows, CCS charging station growth has a long way
to
catch up to CHAdeMO and Tesla Supercharger numbers

As in Europe, more U.S. sites are now including dual standards for DC
quick
charging

BMW and Volkswagen have committed to installing both CCS and CHAdeMO
compatible quick charging units
]
In the United States, there are three competing standards for quick
charging
electric cars: the Japanese-designed CHAdeMO system favored by Nissan,
Mitsubishi and Kia; Tesla’s proprietary Supercharger standard currently
only
used by Tesla’s own plug-in cars; and the Combined Charging System
(CCS), a
standard supported by a total of seven different U.S. and European
automakers which was designed to be the new de facto standard for all
North
American and European electric cars.
CCS has a lot going for it too. It is more compact and less
mechanically
complicated than CHAdeMO, since it simply adds two high-powered DC
connectors underneath the standard J1772 (U.S.) and Type 2 (European)
AC
charge connectors. It shares the same communication and signal pins
used for
low-power AC charging, resulting in just one charging port capable of
both
AC and DC rather than the two discrete charging ports called for with
CHAdeMO.
Yet while the majority of automakers in Europe and North America
support CCS
over CHAdeMO, figures from PlugShare show that there are far fewer
publicly-accessible CCS charging stations in the U.S. than there are
CHAdeMO
ones.
Even in electric-car friendly California, a state with one of the most
well-supported public charging infrastructures in the union, the
numbers of
public charging CCS points trail CHAdeMO ones by around two years.
That’s according to [ PlugShare.com ] (via ChargedEVs) which has been
tracking the number of publicly accessible electric car charging
stations
around the world since late 2011.
Its data shows as of the end of last month there were 324 CHAdeMO DC
quick
charging stations, 224 Tesla Superchargers, and just 104 CCS quick
charging
stations available for the public to use in the Golden State. Tesla
reached
104 Supercharger locations in California last spring, while the number
of
CHAdeMO quick charging stations passed the same marker a year earlier
than
that.
In total, those quick charging stations — 652 in total — combine with
more
than 6,597 public Level 2 charging stations to give the highest number
of
public charging stations of any U.S. state, around four times the as
many as
Texas, which has the second highest electric car public charging
provision
of any U.S. state.
As for CCS? When it was first ratified as a standard, automakers who
supported it — including BMW, Volkswagen, General Motors, Ford and
Daimler —
argued that CCS should be the only officially supported standard for
public
quick charging of electric cars in North America and Europe.
But thanks to the popularity of the Nissan LEAF electric car and
Nissan’s
proactive support in funding the installation of CHAdeMO-compatible
quick
charging stations in key market areas, CHAdeMO has been given something
of a
stay of execution by virtue of its popularity and the fact that dual
standard charging stations aren’t much more expensive to build and
install
than single-standard units.
In Europe, where CHAdeMO exists alongside CCS, Tesla Supercharging and
the
three-phase AC quick charging used by the Renault ZOE hatchback, most
providers have resolved to continue providing cross-standard support
where
possible, with most new installations consisting of triple-head
CCS/CHAdeMO
and three-phase Type 2 installations to cater for all cars. (It’s worth
noting too that European-market Tesla Model S cars use a modified,
lengthened Type 2 charging inlet rather than Tesla’s proprietary
Supercharge
connector, allowing customers to use either DC Superchargers or AC
three-phase charging where available.)
Of late, even Volkswagen and BMW — who recently announced a massive
push on
CCS quick charging infrastructure across the U.S. for owners of the
Volkswagen e-Golf and BMW i3 — have promised to install dual-head
CCS/CHAdeMO units at high-traffic locations so electric car drivers of
all
makes and models can benefit from the extra infrastructure. Initially,
both
firms had been reluctant to support the CHAdeMO standard.
Which brings us to the inevitable question. Which standard should you
choose
on your next electric car?
For now — and ignoring Tesla’s proprietary Tesla Superchargers —
CHAdeMO is
the most popular rapid charging technology by far, with many more
CHAdeMo-compatible cars on the roads than CCS-equipped models.
With more charging stations too, you’re more likely to find a CHAdeMO
charging station than you will a CCS unit.
Sadly, it’s not that easy.
Along with the higher number of charging stations come higher numbers
of
users. To date, there are 75,000 CHAdeMO-equipped Nissan LEAFs in the
U.S.,
along with small numbers of Mitsubishi i-Mievs and Kia Soul EVs.
Combined,
we’d estimate there are no more than about 11,000 BMW i3, Chevrolet
Spark EV
and Volkswagen e-Golf cars in the U.S.
Do the math, and you’ll see that while there are far more CHAdeMO
stations
in the U.S., the ratio of cars to charging stations is far more
favorable
for CCS than CHAdeMO, at least in key markets like California.
