Hi Dex’s Chris, I have worked on a couple dozen Nissan Leaf batteries and I know exactly what you try to do. Unfortunately, the descriptions from the Nissan dealer are deceiving. Let me clarify:
The control (round) plug is entirely different between the 2011/12 and later versions Leaf. When a dealer orders a replacement pack for a 2011/12, it will be a new pack specially made using the *old* connector. Actually the pin signals are electrically the same between the two (see also the service manuals) but mechanically the two are not compatible. There are other differences, for example the car expects 4 temp sensors while the 2013+ pack has only 3. Confusingly the dealer does order two conversion adapters. Those are not plug adapters, but metal brackets that attach the rear of the pack to the frame above the rear axle. Reason is that the designers of the 2013+ packs chose to use two smaller bolts for each of the two brackets, while the 2011/12 packs attach that bracket with a single larger bolt, the same one as the rest of the pack is attached to the frame with. I have no clue why and you could drill 2 holes in the old bracket and reuse it if you like. However, also the 2 plastic belly pan sections under the pack do not fit when installing a different pack, so the dealer also orders new belly pan covers. Then there is the issue of the 2nd high voltage plug. That is why all except one of my battery swaps were: - Open both packs - Swap the new modules into the old enclosure, also retaining all the old wiring and the old BMS (LBC). - Bolt the old enclosure together and reinstall on the original vehicle - Because you keep the BMS with the car, no reprogramming required. NOTE that BMS wiring is different between old and new pack, so make sure to swap *all* wiring to the new cells when you install them into the old shell with the old BMS. Too many people wanted to cut corners and plugged the new cell’s sense wiring harness into the old BMS. Mechanically it fits. The smoke escapes instantly. Hope this helps, Cor.

Since the 2013-2015 pack, instead of one single HV connector, has 2 HV connectors on the front of the pack, one for the motor, the other for the cabin heater: 1) How was cabin heat is supplied from the pack in the 2011-2012 LEAFs as there's no connector on the front of the pack for cabin heat? 2) Please confirm that dealerships use an adapter cable that mates the 2013-2015 pack ports to the 2011-2012 vehicle (best case scenario) 3) If no adapter, is the motor HV connector identical? In other words, if installed as-is, without any mod, the net effect is loss of cabin heat. (worst case scenario). -------------- next part -------------- An HTML attachment was scrubbed...
