HI, I have bought a Nissan leaf 30 kWh battery that I will use as battery storage for my solar system. but it seems that the BMS system on the battery is broken because I can't get the Can bus from the battery. is there anyone who has i can buy a BMS 293A04NP4A from ?

Is the BMS internal to the battery? (That is, is the BMS contained inside the big metal enclosure that all the battery modules are in?)
I disassembled two full Leaf packs. I've got a big box of miscellaneous scrap whatnot out in the shop. If the BMS was inside the battery box, then I probably have one. Let me know, or upload a pic of the part, and I'll poke around out when I'm out there this weekend to see if I have one laying around. You'd be welcome to it, as I certainly have no use for it myself. (I'm not one of the rich guys, but I am using Batrium on my Leaf-based powerwall -- and I'd use the DIY-BMS if I had it to do over again.)
Cheers, John

Hi John
thanks, it will be nice if you have one you don't need. The BMS is located on the side of the long stack battery. (you can only BMS inside the Leaf battery if you have an inverter for high voltage battery, mine is at 180-600 vdc)
Cheers, Tommy

Thanks for the pic and explanation of where it was located. I should have one, if it hasn't been tossed out. I will look when I'm out in the shop this weekend. If I find one, it's yours for nothing but the cost of sending it your way. Where are you located?
Also -- just curious -- what HV inverter are you using? Those seem to be somewhat rare and expensive beasts, for those of us doing homebrew powerwall projects. That's why I tore my Leaf packs down to reconfigure them as 14s, for a more typical inverter (Growatt).

I went out in the shop last night and dug around. I found all the Nissan leftover bits that I still have, but I regret that a lot of the electronics appear to have been discarded. I have the big plug modules, and a lot of the wiring harness / balance leads, but I could not find anything that looked like the BMS part. That stuff must have gotten tossed in the trash, and I'm sorry I wasn't able to send one to you.

Hi,
I've a BMS from a 30 kWh pack. But it's says 293A04NR5A. I don't need it, it's left. I even have contacts. The question is where are you located? I'm in Sweden.
Looking to buy 30kwh Leaf BMS. Is it still available?
Sorry for the late reply, yes, I still have it!

Hi, I'm interested in the Nissan leaf BMS if anyone have for sale, preferably the 30kwh 2013 or later.
