do you mind that the app are you developed could upgrade firmware for 30/40/62 BMSs too? I just two heavily degradated 62kWh packs with the same firmware version. I know about other 62kWh packs not degradated with higher firmware version. Probably they need other than module repair also firmware...

please share photos of the internal of the ariya BMS with detail of the eeprom and main chip code.

disappeared the user? in any case he was suggesting his sw https://forum.kolyandex.su/viewtopic.php?f=23&t=1112

he knows well that chip, he did already dump and reprogram many times because it is a garage specialized in this. Tomorrow I'll ask him to show me the pin that have to be soldered and what program he uses. BTW direct chip reading!

Finally I was able to dump both eeprom memories from a 40 and 62 kwh bms, thanks to the help of the master ECU programmer that is borrow me his garage. His is expert in ECU programming ans super skilled. We desoldered both eeprom of the two processors available in each BMS and read them. The...

not related with service manual, but to your question about different component in different countries. I usually check part number (not harness) exploring models in https://partsouq.com/ where you can select region for leaf models.

HI @explorer232 I've only NAM documentation. is it so different from the EU one? can you share where the difference is?

I only know that they build the module but no idea if soldered or laser welded (I suppose laser welded). So I can't help and I didn't mount the pack by myself, I hope that person did some detailed foto, but was not involved in any deep analysis, is just a driver that ordered a vivne pack through...

I've a report with video regarding a env200 VIVNE pack with a serious problem in a cell. Not yet posted because I've to obfuscate the battery identifier to respect the ownser privacy. Because env200 vivne packs are build from catlm module soldered together by Vivne and these modules assembled by...

Yes, it should be a 24kWh BMS, I've a similar one. thhank you for sharing. Strange that the env200 40kWh bms has the same hardware architecture of the 24kwh leaf, but different to the 40kWh leaf.

Great @ramdoor :) you can start adding front/rear photos of different models with zoom to the main processors an eeprom codes

no, but I'll do editing the original post. is it ok?

I posted photos of a 2012 model. No idea if it is similar to a 2013 one.

if you a so unbalanced cell for a new pack, you can have more issue too, please enable leafspy log, put leafspy enhorizontal en grab a video during heavy load or long accelerations, then share all here. This could give a good idea of the issue of the cells that could be more respect the flaky...

for sure you can help dumping the memory content of the eeprom (probably the same as shown in previous pthotos in the thread). waiting for you contribution :) cheers

Yes, you can directly connect leafpsy to the battery that is a passthrough to the bms, so probably you can connect directly to the bms (BTW I didn't test). See Dala's docs how to do: https://github.com/dalathegreat/Nissan-Leaf-Battery-to-OBD2 Mapping pins to the BMS pins you can directly connect...

is it a 24kWh BMS? strange I was able to dump with 8bit mode. Should I try putting the ORG to vcc too and see the result? In any case I did dump without removing from board.

ground. The chip is set to 8 bit configuration

Houch! I've the leafspy snapshot for the 40kWh BMS but not for the 24kWh one that I received as donation because seems has a failure in can communication. So I do not have any leafspy snapshot for his memory dump

I should have it somewhere, Iĺl check!
