CCS1 and CCS2 --> CHAdeMO Adapters

[JoeS]

This one is quite new on the market - I just sent A2Z a query as to whether they've tested it with our North American i-MiEVs (2012-2016) or with an old Tesla Model S CHAdeMO adapter.

Awfully pricy, even with the $100 off STATEOFCHARGE Tom Moloughney coupon code.
Initial announcement but not a review (yet) by Tom:

Initial reviews on the mynissanleaf.com forum are positive -

Unlike another competitor -

With CCS1 proliferating and CHAdeMO being phased out we may still have some options, including using a Tesla Supercharger Magic Dock...

For our CCS2 worldwide members, here's a brief video and further discussion on the mynissanleaf forum:

A chap on the German forum has successfully tested a ccs to chademo adapter (sold by evniculus) on a 2011 I-MIEV but it didn’t work on a 2014 C-Zero?

Good news, after a FW update the adapter now works with both versions…

Ordered the A2Z CCS1->CHAdeMO adapter from Canada out of fear of the impending 25% tariff and received it on January 30.

After buying a 18650 battery (it was not supplied) and charging the adapter, I successfully used it at a nearby EVgo station. An initial cockpit error on my part resulted in an initialization error on the EVgo diplay (scary), but a second try was successful as the car started charging!

IT WORKS!!

There is a basic translation mistake between the car through the adapter to the EVgo charger: the car started charging at 50%SoC (per CaniOn) but EVgo indicated it was at 80%! The current readings matched.

This old i-MiEV's battery needs help and started charging at 20kW at 50%SoC (per CaniOn) which I did not consider unusual and comparable to a regular CHAdeMO charge, but which rapidly decreased and was normal for this particular car (my worst i-MiEV recently purchased, and sacrificial in case this test blew something up). It's 31.3Ah, and I'm still balancing the cells which were pretty catawampus a couple of months ago but are getting better, slowly.

I ended the test at 56.5%SoC (but indicated 90% by EVgo) and the power level was down to 6.7kW and the battery shows 360vdc with an unbalanced pack. Next time I'll try it on one of my more robust-battery i-MiEVs to see what the power levels are.
Edit: judging by the pack voltage, who's to say that the pack itself is not at 90%?

I also purchased an A2Z NACS->CCS1 adapter and hope to give it a try to see if an i-MiEV can charge at a Tesla Supercharger.

All in all, I'm pleased and can't wait to try this adapter with my Tesla's CHAdeMO adapter as my old Tesla is not retrofittable to CCS1.

I'll be contacting A2Z to discuss the SoC% readout discrepancy.

Here's where I charged: https://www.plugshare.com/location/93993

So, my attempt at using the A2Z Tesla (NACS)->CCS1 + CCS1->CHAdeMO adapters in series to charge my i-MiEV at a Tesla Supercharger proved unsuccessful. The photo below shows the car at a Tesla V3 charger but nothing happened and it was silent followed in a few minutes by a timeout. When I tried it with a V4 charger there was some clicking in the handle but it also didn't work and gave me an error message.

Looks like the EVgo SoC display was correct or at least more accurate than what the car displayed? It therefore looks like the car’s CHAdeMON circuit calculated and transmitted the SoC based on cell voltage? Doesn’t seem to be adapter related, might try a ‘native’ CHAdeMON to verify behaviour?

I’d say the balancing looks worse than it actually is, 30mV is actually quite good, all things considered..

Here in Europe not all superchargers are ‘open’ for non-Tesla EVs, not sure if the same applies in the US?

 

[michael8554]

Is a Mitsubishi MIEV one of the brands/models that Tesla have opened up access to Superchargers in the USA?

 

[JoeS]

No, Tesla has NOT opened up Mitsubishi for access to their Superchargers. I simply had my fingers crossed that it *might* work. Nothing ventured, nothing gained.

Only the later V3 and V4 Superchargers work with CCS1 (for authorized vehicle brands), their location and availability clearly identified on the Tesla app. CCS1 is the North American standard, whereas I *think* that CCS2 applies to the rest of the world.

I also own an older Tesla which cannot be retrofitted for use with the CCS1->Tesla (NACS) adapter; however, I do own a CHAdeMO->Tesla adapter (which I've used often on my long trips, especially in Canada), and one of these days I'll get the courage to try these CCS1->CHAdeMO + CHAdeMO->Tesla adapters in series. With an electric car out in the boonies one can never have too many adapters...

has the A2Z-NACS->CCS1 charged successfully on a CCS EV ?

 

[JoeS]

has the A2Z-NACS->CCS1 charged successfully on a CCS EV ?

Yes, I tried it on a friend's Bolt (just before I did my experiment) and it worked just fine using my Tesla app. I have given away my previous Lectron Tesla (NACS)->CCS1 adapter so wasn't able to try that combination on the i-MiEV.
