+1 Nissan have been terrific hosts!

Its slow but posted about 20 pix on FB yesterday. And yesterday was non stop from 8 am till nearly 10 but today promises to be the most exciting but also the part we will be least able to talk about but just the opportunity to be part of all this has been truly wonderful
Agreed Wednesday was great! We got detailed tours of the Oppama plant where all our LEAFs were assembled and another tour of the Zama plant where our battery modules were made. We also met with Andy Palmer, Roel De Vries, Simon Spoule and Jeff Kuhlman to give our suggestions on how they can improve their LEAF messaging. I will say that I felt they were sincerely listening, so we felt heard.
We have no pictures from the battery plant, but we got lots of pictures of the manufacturing plant. I don't have Facebook, so I haven't seen Dave's pictures yet, but we all have pictures of similar things. I'll post what I got when I have a chance, but I'm generally regarded to be the world's worst photographer!
Some notes on the 2013 battery:
- The module case was modifiied to reduce weight and materials used. They claimed a 30 kg weight reduction for the LEAF battery just from that change.
- The changes to the 2013 battery module chemistry were mainly intended to reduce cost. (There has been some mention of improvements in thermal capabilities, but the battery experts did not confirm that. They indicated there may be small changes in battery characteristics, but weight and cost were the two major changes.)
- The 2013 battery modules are compatible with the 2012/2012 LEAFs.
Some notes on the drivetrain:
- The redesign of the motor was intended to improve efficiency. They said efficiency is improved in the speed range of 40 MPH to 60 MPH.
- There is also some efficiency improvement which comes from integrating the motor and inverter together and thereby reducing wiring losses. It is clear that the main reason to integrate the electronics is to achieve optimum manufacturing efficiency. With this change, the 2013 LEAF assembly is more similar to the assembly of other Nissan cars than was the 2011/2012.
- I asked about the reduced torque, but I didn't get a satisfactory answer. However, they did confirm that with the lower weight of the car, 0-60 times are improved by about 3%. (I will point out that the torque on the specification sheet is peak torque only. It is possible that torque over a range of speeds could be higher on average, even with a lower peak.). I will try to learn more about the drivetrain today, I'd possible.
- They are continuing to work on the GOM, even after the 2013 release. We should see something in the future.

Hopefully we get a 150 mile range LEAF at a similar price point within 5 years.
Yeah, the battery changes for 2013 are incremental improvements. The current LEAF battery technology will likely continue to be tweaked going forward. We may hear more in today's meetings, but, as Dave said, we likely cannot say anything about some of what we will see/hear today.

From the looks of things they want you to have leather if you get the top of the line audio system and 17" wheels. Maybe this is a USA only marketing thing that Nissan Japan HQ doesn't follow closely, but I do represent a small contingent that don't like being forced in to leather seating to get other options.
Like you, I also prefer cloth to leather, but I think all of that is set in stone for 2013.
I hope Nissan continues to work on R&D for charge station finding built into the car. Someday it would be great if the Nav could show you which nearby charging stations were _available_, in other words it would be updated to mark which stations were already being used by someone else at the time. Also, it would be great if they had better pictures / directions to the charging stations. They could look at sites like http://www.plugshare.com/
" onclick="window.open(this.href);return false;, http://www.recargo.com/
" onclick="window.open(this.href);return false;, https://na.chargepoint.com/index.php/charge_point
" onclick="window.open(this.href);return false;, etc. for ideas.
We may meet people in this area today. We will give them your feedback.

Will a LEAF ever charge at a Tesla Supercharger or SAE Combo-plug station? I don't know if Nissan has even considered making adapters for these. I am guessing not, but it seems worth asking just in case.
We discussed this some on Tuesday night and Nissan is clearly frustrated by the whole SAE combo plug issue. In any case I can ask if they plan to offer any interoperability options in the future.
