Leaf cell discharge curves

There is lots of speculation about various leaf cells having different discharge curves. I can confirm that 2010-2012 cells have a different discharge curve to 2015, as I repacked a battery and retained the original LBC. I now have a fuel gauge that is very non-linear, with lots of capacity available in the turtle-0-1 fuel bar range

Does anyone have the discharge curves of the various cells that Nissan used over the years?

ZE0 (2010-2012MY)
AZE0-0 (2013-2014MY)
AZE0-1 (2015-2016MY)
AZE0-2 24kWh (2016-2017MY)
AZE0-2 30kWh (2016-2017MY)
ZE1 40kWh
ZE1 62kWh

TIA for any help

Re: Leaf cell discharge curves

I'd just like to second this request, been looking all over and can't find much at all online...

If you can reach the proprietor of MUXSAN in the Netherlands he probably has that data.

Re: Leaf cell discharge curves

Ok, I'll start the ball rolling with the link below. It gives the ZE0 2010-2012 24kWh and ZE1 2018 40kWh discharge curves. Can someone please post these as pictures so they are available here forever, I don't know how long the link will work

Re: Leaf cell discharge curves

Thanks for that,

The 30kWh battery seems to be the mystery, can't find a thing regarding it. Having watched my own 30kWh on Leafspy whilst discharging, what I can say is it's quite a different discharge curve to the 24kWh version.

Different from the ZE0 (2010-12), yes. The battery chemistry was changed in late 2013, then again around 2015 when the lizard batteries were released. These changes added nickel and cobalt, from what I understand. The ZE0 cells were LMO (lithium manganate)

My experience has shown a significant difference between ZE0 and AZE0-1 (2015, so probably a lizard pack

But it would be good to have the discharge curves to more fully understand the differences

Re: Leaf cell discharge curves

The battery chemistry was changed in late 2013
A small correction: the chemistry was changed from the original chemistry, which I've dubbed the "Canary" pack, to the much improved "Wolf" version, in April of 2013. So January through March builds have the old, bad chemistry, while April (possibly with a tiny number of exceptions) was the beginning of the better batteries.
