Good point about the manufacture date. However if the serial is not on the every module (like on every module in Prius) you would not have a clue if someone had aready mixed old and new.... I created small program for scanning and checking quickly the dates in Toyota. Will have a loook at the Nissan serial structure - whether it follows the pattern .... As for the "card" - if I get one - we can experiment ....Turbo3 wrote:...... knowing the battery serial number might tell you something about when/how the battery was manufactured if enough people report their data. Parts of the serial number might change based on chemistry or other interesting factors.
I would guess the "Battery Programming Card" generates a special code number required to marry the VCM and BMS ECU using the battery's serial number. A CAN trace of the process would tell us more about what is going on. I would thing the PCMCIA card includes an encryption chip so it is not going to be easy to bypass it. I don't recall seeing that card for sale so probably only dealers can get it.
