Unfortunately, there is no easy place to mount the socket (thanks Toyota), and you wouldn't want to replace the J1772 socket as then you wouldn't be able to charge at home anymore.
Theoretically you could install a Supercharger port on any EV. There are just 3 problems to solve: you need a compatible inlet, a sufficient connection from that inlet to your battery, and the appropriate hardware/software to execute the protocol.Michael Bornstein said:theoretically you could install a Supercharger on a 40 kWh Model S
Making our cars work with ChaDeMo requires solving the same 3 problems. The difference is the inlet is readily available (but it's not cheap!) and the chargers are public (well I'm not sure how many Nissan dealers would like the idea of us charging there though...) The protocol stuff is not easy to figure out (this is what Tony's working on now I believe), but at least we don't have to commit fraud to get it to work.As for the Chademo charger that some Leafs use, it would take more than a simple converter.
To be clear, adding quick charger support (whatever kind) requires a separate inlet that connects directly to the battery via high-voltage DC (more like ~390V, as Tony pointed out) - it's a separate system from the J1772 inlet and on-board charger (although those systems could somehow be involved in the protocol implementation.)The Chademo is 480VDV and the J1772 is 240VAC
There are ChaDeMo chargers that output less than 50kW. Some output 44kW and some output as little as 25kW. One of the DCFC manufacturers rationalized that since some cars taper so quickly down to that level, that there was no point to engineer it for more than 25kW. The Misubishi i comes to mind as a vehicle that can't take a lot of juice.fooljoe said:ChaDeMo can supply around 50kw.
Michael Bornstein said:Whether or not Tesla allows it is besides the point. RAV4 EV's don't have a Supercharger port. I once spoke to a Tesla tech and was told that theoretically you could install a Supercharger on a 40 kWh Model S (if they exist) even though Tesla doesn't market the ability. Therefore you could theoretically install a Supercharger on a RAV4 EV. Theory aside, would Tesla authorize the installation? I doubt it. I have heard that some Supercharger stations include a J1772 plug (specifically the one at Harris Ranch), though I haven't personally seen it. I know that the station at Laval Road doesn't have one.

Tesla designed their car to take electricity from almost anywhere. Every car is delivered with a J1772 adapter and they have a half-dozen different wall plug adapters for their mobile charging cord (EVSE). They also have special high power contactors in the car to allow the SuperCharger to deliver DC current directly to the battery from the same charge port, bypassing the on-board charger. A Leaf does not have these contactors because it has separate charge ports for AC charging from the wall and DC charging from a CHAdeMO station.jrustin22 said:Michael Bornstein said:Whether or not Tesla allows it is besides the point.

I don't understand then why do I see a Tesla Model S being charged at a ChargePoint station, using the J1772 Plug if they are not compatible.
I guess Tesla wired the model S to use the J1772 and the supercharger.
TonyWilliams said:With our JdeMO(tm) project to install CHAdeMO in the Rav4 EV, there is no involvement with Tesla or Toyota, or their dealers. We will mount the CHAdeMO socket under the hood; there is no change or interaction with the existing J1772 AC power inlet.
Toyota worked with Tesla to quickly make a compliance car. It was never their intention to make a viable long distance EV. That is the reason you don't see any quick charge connection on the RAV4 EV. Toyota is a member of the CHAdeMO alliance but they just didn't bother to engineer it into the car.Bugatti said:I am not sure whether or not it is possible but I do know that Tesla and Toyota partnered up to make this car so that makes me wonder whether or not it would be possible to charge.
