Just learned on a Nissan Leaf Test Drive

My friend took me to look at a Nissan Leaf. Lots of ooogles at my S model. I did learn 3 interesting things about their product/package:
1) Brakes operate using magnets so that there are no pads to replace. I do not know the effects of power consumption to do this vs activating disk brakes. Also, the TESLA is quite a bit heavier than the Leaf. (4,647 lbs vs 3,340 lbs).
2) Nissan Leaf has an option to use a quickcharge network which delivers 480V DC through a much larger Plug, (about 5" dia.). Can our Tesla S utilize this network or is the SuperCharger network the only one possible?
3) Nissan is allows each buyer 10 free rental car days per year for trips where they don't take their Leaf. I believe I understood that the car must be left at the dealer during this rental time.

@jat - I guess I can see that, but honestly, I (personally) would never drive a car that's that ugly.

@jat - Also, you have to take into consideration that the average person WOULD need an ICE car in addition to the Leaf, given that their loaner program isn't sufficient or practical for those who take more than a few trips.

@Tanner - assuming you drive ~40mi/day, the fuel savings of the LEAF would allow you to rent an ICE for a weekend every month. So, I wouldn't say it doesn't work as a sole car.

So please give me an education on the CHAdeMO charging (that must be the large round plug on the left) VS the Tesla fast supercharge. What are the issues with being able to connect to this type of charger in the US? where does the supercharger connect to the TESLA? I understand there are CHAdeMO local where I live in Tennessee and it could be quite handy to use... especially for a trip.

@pencil2man - AFAIK, there is one CHAdeMO charger in TN at a Cracker Barrel. CHAdeMO is 45-50kW, while the Supercharger is 90kW (rumors of upgrades to 120kW). Currently, there is no adapter to use a CHAdeMO charger with the Model S, though Tesla has said there will be in Europe and there are rumors of it in Japan. The Model S only has one charge port, which is used for both AC and DC charging.

is there an incompatibility that the S can't be charged through others higher rate charging systems? I may have misnamed it, but I understood from a Leaf owner there are multiple quicker charge stations which use the larger round port on the left of the charge cover/area on the car.

I have that port on my Leaf but have never used it. There are very few stations that have it. In our area the top parking lot company has put in a number of 240v ChargePoint terminals which is great, because you're normally parked there a while. However, we were hoping that Walgreens would have rolled out the high voltage terminals with ChargePoint when they started their network, but they just have 240v. If ultimately we can get retail locations like Wagreens and Starbucks etc to install high voltage charging stations, EV use could really gain traction. I'm purchasing a ModelS primarily for the range. With the range that we have in the car, there is little need to get a quick charge, unless you're planning on very long trips.

@pencil2man - that port is CHAdeMO. The great thing about standards, is there are so many of them. At its basic, it is just a regulated DC voltage supplied to the batteries, plus a protocol (whether serial like SAE1772 or Tesla vs relay closures with CHAdeMO) that exchanges information between the car and charger. As long as the capabilities and requirements of both overlap, it should be possible to build a converter. See many threads about CHAdeMO support in the Model S, but the bottom line is we don't know if it will ever be available in the US. My personal feeling is yes, but only if it takes off (CHAdeMO has the installed base of cars and chargers, while SAE-DC has most of the manufacturers).
