Hi Guys, new to Nissan Leaf (Just bought one). Is it possible to connect the DC Chademo connector to CCS via an after market cable? 8KW CCS is too slow... :D
 
Not that I know of, and not likely.

Chademo and CCS use different communication methods and messages. It might be possible to have a small computer that would pretend to be a CCS car on the CCS side, and a Chademo charger on the other side, and control a power relay to make the real connection once everyone is ready. A large amount of software development and testing would be needed. This isn't a cheap or simple cable.

Yes, as Cademo slowly fade of into oblivion.. will be necessary. :shock:

It's Type 2 AC connector and a CHAdeMO DC connector. Type 2 and CCS are different things; CCS ports have a type 2 connector, but not all Type 2 ports have the CCS DC connector (2 large DC pins and all the protocol that goes with).

Yep, although CCS2 is Type 2 + DC pins so it is not too surprising that OP is mistakenly calling the AC port 'CCS'

The connector on the right in the photo above is a J1772 connector. As mentioned, CCS incorporates this connector, but the LEAF cannot use CCS. Wow--I just confused myself.

So your specifications should read that the LEAF supports 6.6 kW J1772 charging (not CCS) and 50 kW DC CHAdeMO fast charge.

I just saw on Wikipedia that a CHAdeMO 2.0 specification allows for up to 400 kW at 1000 V. I wonder if this will be implemented on LEAFs, and if this suggests a continued CHAdeMO future.

This is a CCS plug and connector:

Australia uses the Type 2 connector for AC charging, not the J1772
 
As a further visual aid, https://greentransportation.info/ev-charging/range-confidence/chap8-tech/ev-dc-fast-charging-standards-chademo-ccs-sae-combo-tesla-supercharger-etc.html has some pics.

Under "China’s fast charging system(s)", Type 2-Germany is Mennekes Type 2, is in wide use in Europe. The Type1 in that table is our J1772.

Under "DC Fast charging standards – CHAdeMO, CCS, Supercharger, China", in Europe, their CCS plug is Combo2, which is Mennekes Type 2 up top + two extra pins.

In the US, our CCS flavor is Combo1 aka SAE Combo which is J1772 up top + 2 extra pins below.
