Without the CVLI, you have little to judge actual or potential
capacity loss until 15% is lost, and the first Capacity-Bar disappears.

I want to know now, not March 2013 !!!

I would also like to know how things are going with the battery pack for the same reason. I'm not a total data hound, but I do appreciate having the ability to investigate and monitor the health of any system we own. For example, we have detailed information on our PV system since it went online, and I now have the confidence to monitor it less closely than when new. Having historical perspective, I have not gone crazy looking for a replacement for a panel with a cracked facesheet, but I am monitoring output while shopping around. Similarly, if I had visibility of cell-pair performance, I could build a personal confidence in the health of our Leaf investment and know better what to do if/when capacity starts to slip. Unless the price is outrageous, we'll pay to have the CVLI done when the car is a year old in September.

Digressing, I expect that the ability to read this data from the car will eventually be divined by the likes of ingineer and garygid. Keeping it as an in-house secret until then may be seen by Nissan as a competitive need or (presumed) requirement to ward off potential lawsuits like those currently with Honda Civic Hybrid mileage, but I think it is unproductive. The sad part is that this same data and more, is currently available to owners of heritage NiMH RAV4-EVs. All one needs is a working Palm, an interface cable, and some homebrew software, all available from within the owner community.
 
Took my Leaf in for the update and was set on having the CVLI done. Made sure I arrived with only 1 bar and had printed copies of the relevant service manual pages. The customer liaison didn't really like me asking for specific tests but I made enough of a nuisance of myself that the actual Leaf specialist came out to talk to me and things went a lot better at that point. Was very informative and even let me look at the setup. Seemed to actually appreciate an informed customer instead of resenting it like the front man.

We paged through all the cell-pairs, identified the max and min (3733mV and 3668mV respectively). Was hoping to find a bad cell to explain my reduced capacity, but he said 65mV max-min wasn't bad.

Wouldn't give me a printout, though. Very apologetic but apparently in the class they really drove home that under no circumstance could this information be given to customers. Really didn't want me to even take pictures of the setup so I was stuck with committing the values to memory. While I disagree with this policy - it's my car afterall - I don't blame him for not wanting the risk his job for a stranger. Was actually pretty friendly and I walked away feeling like they at least tried to appease me as much as they were permitted.

Pretty cool setup. At one point he was able to consult with Nissan engineers at a remote site (would have been late for Osaka so not sure where) and the remote engineers were able to directly read and examine the canbus messages. Ran out of daylight so I will bring it back on Monday for more tests (this time at max battery charge). Hopefully we'll get to the bottom of why my capacity is low.

dont worry about it. pretty soon, you can monitor it yourself on a daily basis for a few hundred dollars. Phil has a monitor in the works that will tell most all.

no pricing announced but guessing it will be $150-250
