I'v replaced old 2012 Leaf cells with 2013 cells...

Tue Dec 11, 2018 3:11 pm

Hi all,
I've just completed a battery cell swap on my 2012 52000 mile gen 1 Leaf after the original battery was down to 74% SOH so I brought a 2013 battery of the later chemistry and just swapped the battery modules leaving the BMS and original bus bars and wiring in the original battery case.

So far so good! Its all working ok and I've been on a 40 odd mile run and the SOH, Ahr and Hx have slightly improved already.

I hope to keep updated with progress on this forum :D

I've put a few pics on facebook under scorpioelectronics/uk

Good work! You can help a lot of people by documenting the process in as much detail as possible.

The BMS is learning the new capacity of the battery pack.
I've done a few long journeys in 5 days and the Ahr has gone from 48ahr to 54ahr.
The SOH has gone from 73% to 83% and HX has gone from 65% to 76%.
And the Gids have increased from an average of 205 to 233.
So far so good!
I've put some leafspy screen shots of the various screens on the scorpioelectronicsuk Facebook page.

I've been looking for someone who has done this for a while.

I'm looking to do the same as have newer gen2 cells and going to throw into a n older leaf with gen1 cells in.

Question is is it a case of swap out and plug and play?

No programming of anything and was there an order for disconnection inside the pack as was told there is.

Thanks

I would read the posts by Cor at http://www.mynissanleaf.com/viewtopic.php?f=51&t=21997.

Remember that you are dealing with deadly high voltages and a pack that weighs over 600 lbs attached to the bottom of the car.

'19 Bolt Premier
'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Hi Thanks for the reply,

Getting the pack from under the car on my drive would be a task which im thinking about how todo without shelling out more cash .

Im happy to work on the leaf and have all the high voltage equipment to do safely and aware of the dangers too so thats covered.


Thanks for the link too i will have a good read of this.

Im also searching all over for as much info on this module swap like:


1. Any order to follow inside the pack to ensure no issues (like doe the battery controller need removing first and connecting last etc)
2. Is there any programming of the BMS etc once you swap the modules or is it just a case of the BMS relearns as car cycles. (This thread indicates its relearns yes)


Thanks again
