Department of Energy - Chademo vs. CCS

According to the DOE site today (some articles where quoting the information source)

Chademo Locations: 2,492 (Interesting that Chademo quotes 3,000 but I wonder if that counts the total number of station points as some locations have 2 or more stations/charging points at the location)

CCS Locations: 2,258

So, in spite of the joined forces of GM and Germany, CCS doesn't yet have numerical advantage. Guessing that will happen in a year or so given trends.

Most of the DC fast chargers that I've seen in Oregon don't even have the CCS connection, only Chademo.

I use Blink and the West Coast Electric Highway chargers.

CHAdeMO has major disadvantages and deficiencies that the single number in the OP do not expose:

1. 50 kW or less power
2. Concentration in urban areas
3. Typically 1 - 2 taps per location
4. Frequent poor maintenance and out of service or unavailable.

For most EV owners today the point of a DC charging network is to enable reliable and convenient long distance driving. In the USA CHAdeMO is for the most part anything but since it was designed to support extended local driving with 24 kWh LEAFs.

CCS has been growing due to the EA expansion, and as a political sop EA adds ONE 50 kW CHAdeMO tap to locations that typically have 4 - 8, 150 - 350 kW CCS taps. Saying the CHAdeMO and CCS are equivalent at those locations is ridiculous.

If you count the total handles, Chademo shows even a wider lead, and there are still more multi station Chademo stops, mainly on the coasts.

CHAdeMO in the USA is in caretaker mode, and a neglected one at that.
I showed you the data from the AFDC database: of the last 200 CHAdeMO locations installed in the USA, 70% are from EA. Of the remainder I am willing to bet good money that with few exceptions, CHAdeMO is the step-child with one plug. I'm not sure about EVgo or Chargepoint but the EA installations put the CHAdeMO plug on a station that also has CCS and only one can be used at a time. How is that for a hint ? :lol:

I don't know how much more obvious the data can be.

Asia might be somewhat different, since Japan and China have agreed on a joint standard that will at least provide low power backwards compatibility with CHAdeMO but I cannot imagine it being competitive if the new standard is faster.

Europe has embraced Type II CCS. End of the CHAdeMO story there, it is in formal caretaker mode.

Two more Chademo and two CCS stations opened up this week about 30 km away. All are 200 kw.

^^ And for you, Tesla just announced that their 50 kW CHAdeMO adapter is now compatible with Model 3.

Where is the Chademo located?

Thanks

Kelowna Airport in the B.C. interior. We have driven by it a few times but haven’t stopped yet.

That’s kinda cool.
