Likelihood of a CHAdeMO adapter for the Model S

[iridium]

Here's another vote for wanting a CHAdeMO adapter. Washington and Oregon recently put in nearly 50 high current DC CHAdeMO chargers along all the major roadways as part of the West Coast Electric Highway project. In a sense, we already have a complete Supercharger network installed up here that Model S owners can't use until Tesla puts out an adapter.

+1

I was surprised how many are up here. With an adapter getting around the northwest would be no issue.

I am waiting 'patiently' but want to go to Hood/Bachelor soon.... please. ( and not a 20+ hour trip to get there)
these adapters should have been out before the car!

Hey, I'm looking forward to the adaptors too, but let's not go crazy. Would you rather have the car without the adapter or the adapter without the car.

ya, the car rocks even without being able to go skiing this year! but it would be nice ;>

But, since there is a network in place, it would be nice to be able to use it ( when I got my car I had no Idea there was a CHAdeMO network in OR/WA already so no question about the car vs adapter )

I agree, being in an area with a substantial network and being locked out of it with such a premium car is a real drag.

I'm sure that is how Roadster owners feel about the Supercharger Network.

Generally speaking, how quickly do we anticipate a Model S charging on a CHAdeMO charger like those in Washington and Oregon? I assume it's not nearly as quick as a Tesla Supercharger but does anybody had a feel for what kind of charge speed we can expect?

 

[ahimberg]

I think the installed CHAdeMO is ~50kW, where supercharger with a model S is up to ~90kW. So about half the rate of a supercharger, but still >5x faster than a typical J1772 (or 2.5x faster if you find a high amp J1772 AND you have twin chargers on your model s)

Regardind Supercharger only charges above 50 kW for a while (about 40% of the average charging time), I assume with CHAdeMO it will take almost same time as Supercharger when SOC is over 60% and maybe one and a half times when under.

Rather than post a boring > 1 hour video, I plotted a graph for ya ...

Edit: This was done in ~20F weather so there weren't any effects of tapering the charge to keep the battery temps down.

Yes, Ecotality has installed a bunch of Chademo stations in the PHX area lately. an adapter to allow the MS to use that would do wonders for the charging options for MS owners here. I'd dare say having one would actually impact sales for the MS.

Update: just checked as of today there are 22 Chademo stations in the greater PHX metro area. And they are nicely spread out around town.

I think with the Chademo adapter on a 50kw station the charge times will be very close to the Supercharging times due to the steep decline in charge speed during the session. Here is a great study on fast charging between a 25KW charger and a 50kw charger: http://www.americas.fujielectric.com/sites/default/files/DC%20Quick%20Charging%20-%20FEA%20Comparison%20Study%20%20%2825kW%20vs%20%2050kW%29%207-3-12.pdf. 50kw charger is only 7-10 minutes faster charging a Leaf than a 25kw charger. My guess is that a Supercharger will only be 7-10 minutes faster than the adapter on a 50kw Chademo charger on the Model S.

I just noticed all the CHAdeMO charging stations in the bay area, a place I travel to often on the weekends, so now I'm really hoping for an adapter.
Would make the trip from Sacramento to Golden Gate bridge to Santa Cruz a lot faster

The DC chargers in WA and OR are either 60kw and 50kw, depending on when they were installed.

Here are the spec sheets:

The DC chargers in WA and OR are 60kw.

"CHAdeMO ... option"
Does that mean they have J1772 or some other connector as well?

 

[EarlyAdopter]

They do also have J1772's on each station, but I think the "CHAdeMO option" indicates that the DC charging unit is modular and potentially upgradable to other DC connectors and charging protocols in the future.

I keep forgetting so I'll just ask...

Is the J1772 capable of the full 60 kW or limited to lower than that?

 

[EarlyAdopter]

J1772 is typically just 208v AC @ 30A = 6kw. I believe that's the max the connector has been UL certified to. So way less than a DC rapid charger.

 

[ChadS]

Yeah, the state (WA anyway, I'm not positive what OR did) put out an RFP for CHAdeMO stations, and then after Aerovironment won, begged them to put in J1772 stations as well - for free. Aerovironment, like most companies only makes 30A J1772 stations so 30A is all they got. Too bad, as 70A units all over WA and OR would have been awesome for the Roadster.

... and for Model S.

... and for Model S.

Very true. I left that out because Supercharger buildout OR a CHAdeMO adapter the Model S would be better for the S. But we don't have either of those here yet, so yeah 70A L2's on the West Coast Green Highway would be a very welcome addition. (I did try to get the state to have them put in before this all happened, but given that they were begging for any L2 and AV didn't have 70A units, it was a no-go).
