I specifically asked Mark about Chademo vs. SAE L3. He said Nissan is staying with Chademo.
In a separate thread it looks like they will be adding inductive charging under the vehicle in 2014.

open circuit voltage. The only time this used is when the car has been at rest for some time (length?). Once you start driving, The car does not know the OCV, but can make an approximation by counting amp hours consumed among other calculations to provide the current state of charge for the battery while in use. Once you turn the car off and let it rest, the computer can then get another reading of the OCV when you start your next trip.highcountryrider wrote: Sorry, what is OCV in this context?
Would this imply that if you've been driving for a (long) while and/or the battery is low and you want to get a more accurate estimate of DTE, that you might (pay attention to your driving speed for a few miles to smooth your average consumption, then pull over and) shut the car off and "reboot" it?palmermd wrote:open circuit voltage.

I find this particularly interesting in that I sometimes will come back out to the car after stopping somewhere briefly on the way home to discover that I suddenly have noticeably less charge remaining than I had when I parked it a half hour earlier. It is of course particularly noticeable when I stop with just a bar or two of charge left because I come back out and discover the remaining bars entirely gone and immediately get the out-of-charge warnings. I had wondered if turning the car off and on *caused* a loss of charge (to fill the brake backup power capacitor or something) -- and that perhaps it was safer to head straight home rather than trying to squeeze in another errand if my charge was getting low. Interesting to think that perhaps part of what I'm seeing is just a correction of the previously estimated state-of-charge.palmermd wrote:open circuit voltage.

They have helped by making less expensive hardware, and CHAdeMO chargers are finally getting their UL approvals.edatoakrun wrote:Any discussion of how Nissan can assist in US DC Charge infrastructure development?
I think I heard that the 6.6kW will actually be in the front of the vehicle, with the layout of the components under the front hood being somewhat redone for the next model refresh.TonyWilliams wrote:Oh, they had an answer... no.
