Will I need to ask dealer to pair the battery or do swap BMS? Benefit of this that I would be able to cell my 8 bar battery.
If you use the tool, you won't need a dealer at all. If you don't use the tool, you'll need a dealer to activate, not swap, the BMS, which my local dealers refused to do. Some are more willing to do so. Keep in mind the BMS is located inside the battery pack, so when you swap the pack, you swap the BMS. "Pairing the battery" is the same thing as "pairing the BMS"--you're linking the BMS to the VCM (vehicle control module).
Either way, you'll have your old 8-bar battery that you can sell for solar projects, etc.
Yes, that's what I talk about. From that perspective I start to realize the amount of work, even for DIY. I keep forgetting it's not a toy but 1.5 ton car, even if it looks like a toy. BTW I don't see any difference in 2012 and 2013 bodies.
Yes, and you might have to swap a good number of the wiring harnesses, and be super careful, because the pinouts may differ. Keep in mind that while the body did not significantly change from 2012 to 2013, it was a refresh, so many of the connectors, wiring, and harnesses are totally different. You'll essentially have to rebuild the entire car and your donor car better have basically all the parts.
Can you advice on if it's BMS reset victim or not? I updated previous post with the link.
I don't know if this is a BMS reset or not. The 51 miles seems like a reasonable, but low, estimate for a 70% charged 85% SOH pack. If not a BMS reset, I suspect this pack is about to hit 11 bars soon. Any way to get a Leafspy reading of that battery pack?
Keep in mind the miles remaining is affected by outside temperature. If that picture was taken on a 2011, 2012, or 2013+ S-trim when it was really cold, it might be severely lowering the estimated range, due to the inefficient heating system.
If a BMS reset occurs, I fully expect the range estimation to be the full estimate when charged (~100 miles), as the BMS would be telling you to expect max range. Then, as you drive the car, the range estimation should plummet very quickly because for each mile you drive, you're using 2 or 3 miles of the 100 mile range.
Is this prospective battery pack a gen1 or a gen2 pack? Personally, I would only be interested in buying Gen2 packs. Gen1 packs will degrade very quickly. https://youtu.be/fqAbiyZqp1w
Thanks LothSahn, you're just priceless source of Leaf knowledge!
You are very welcome!
