I doubt there will be much improvement in charging power until Nissan installs a 35+ kWh battery.
No need to look up that 1975 act. I have the Nissan warranty book right in front of me with an obvious disclaimer that makes it crystal clear that using non-nissan equipment violates the warranty.TomT said:I suggest you look up the Magnuson–Moss Warranty Act...

I think you're missing something.... I think it's quite a bit more money to buy and install DCFC than 10-20 kW AC. Further, I think the 10-20 kW AC will be "backward compatible" with existing vehicle J1772 ports that can only go as high as 6.6 or 3.3 kW. So, I think there's an argument to be made for the competitiveness of the 10-20 kW AC choice, from the standpoint of decision-making as to installing public EVSE, especially if, in the end, it costs not "that" much more installed cost than under-10kW AC.

Nissan just won't come out and say that.

GaslessInSeattle said:I would love to be able to do 20kW charging on the Leaf. currently, the unmodified Leaf is not even fully J1772 compliant. Nissan failed to meet the protocol even though it was well established before the Leaf went into production. the Leaf can't understand the pilot signal from a 20kW, or anything over 70A station including the CS 100, even though it can handle a charge from such stations because it regulates the charge on board. clipper creek is allowing Sun Country to install dual amp CS 100's that will charge the Leaf as well as all other EV's, but only at their respective rates determined by the charger in the car. I imagine these will be available to the public eventually. All of the stations that are slated for WA state will be 20kW capable. Sun Country is talking about expanding all over the US as it has with it's 1,000 stations across the Canada, so a 20kW mod for the charger in the Leaf could prove quite valuable fairly soon.
If there is a high amp mod out there that works, I'd consider it after my Lease ends. I suspect there are going to be tens of thousands of cheap used 2011-13 Leaf's unloaded on the market in the next year or two as the original leases end which could make the total cost of purchase and modification very affordable.
GregH said:No doubt a new 80A capable EVSE is a lot cheaper to install than a DCQC (at the station level). That wasn't my point. I was merely speculating as to the future momentum of this movement. In the next few years are we likely to see more 80A EVSEs or DCQCs in public locations? If you were building a new EV to market in 2015 or 2016 and you were trying to decide what kind of charging capabilities to include, would you (the manufacturer) pay for a higher power on board charger or just slap on the DCQC interface?
Or from the consumer side, would you rather have a DCQC port or an 18kW onboard charger? (assuming both cost the same.. although the incremental cost of the 18kW charger is probably a lot higher than the DCQC port). Yeah I know.. why not both right? It's just a matter of $$...
Some of the Teslas can pull 80A AC... is there a push from the drivers to have 80A EVSEs installed in public? How successful have they been?

jlsoaz said:So, the question becomes, could the Leaf (I have a 2012) be modified to accept this fast(er) AC charge. I"m assuming that initially Nissan would say "uh, no, we're not going to do it" but my question isn't whether Nissan would want to, but, just in theory, what would it take, technologically, approx. how much might it cost, and what concerns there might be about wear-and-tear on the battery (as with DCFC).
