To date we have been running the Brusa NLG513 charger in manual mode limiting the pack voltage to 388V, sacrificing some range for charging safety. We recently have been working on the programming to read the individual cell voltages through the Nissan BMS such that we could turn the Brusa charging parameters on/off, amperage up/down as the pack charged. We have been having one heck of a time getting the data out of the BMS. And now we know why.
We think this is a 2013 BMS, but the wiring from a 2012 is every so slightly different. If anyone has a table from Nissan to confirm which diagram we should be following? If anyone has a new/used version of this same BMS to share with the project?
Thank you for the information about the ability to program the BMS. How can we access the firmware in the 70f3236bm1gc chip? Which read write programmer is suitable?
