Large format EV cells from electric car

I just wanted to share a picture of two modulesone of my buddies hooked me up with...

They came from an EV Fiat 500e

6S (24v)
4.2v per cell max
I think its about 1.5 to 1.8 kwh total

Still trying to figure out what to do with them, but I am thinking of building a small solar setup and use it for my bench power for charging / testing 18650 cells. Would pair up well with the input voltage for my iCharger and other hobby chargers.

I know a guy that could put them to good use.

Sweet find. How old are the packs? Cycle life?

Really not sure the background on them... but they seem pretty healthy. They came from a group of people who build DIY electric cars and no longer needed these packs as they opted for other with a better storage density.

They take and hold the max charge, no self discharge, and everything is very well balanced cell to cell. I haven't done a full charge / discharge since I am not used to working with such a large capacity, but my iCharger is capable of an external load for discharge so I plan on doing that sooner or later.

I have a total of two modules. I really wish they were 7s, but I am not complaining. I think the Victron SmartSolar charge controller have adjustable thresholds so I might give that a shot. Right now I am just using a hobby charger and various 24v loads like lights, chargers, and DC-DC to use them for 12v items.

Here is some more pictures....





Here is two 12v SLA batteries out of an APC unit... 17Ah@ 24v




Compared to the pack made by Bosch / Samsung




Its about the size of a regular car battery...

My biggest regret is I had the chance of buying as many as I could carry (on a pallet) for $100/kwh, but I wasn't really ready for them at the time. They really seem like quality, and a lot easier than building up the capacity one 18650 at a time.

Wow that's a great price

Not sure what country you are in but if that was in the US and that deal come up again I'll take some of them!

Hello,
located continental northern Europe,
so far I have been handling 1400+ kwh of second life ev/phev batteries since 3Q2016.

Best batteries to source are:
1) YUASA LEV40/50 cells to be found in Mitsubishi Outlander PHEV, Mitsubishi I-miev, Citroen C-Zero, Peugeot i-On
2) Nissan Leaf Gen 1 + Gen 2, all 24Kwh, Gen 3 = 30Kwh battery not good since they changed the terminal lay-out
the Nissan E-NV200 is same spec as Leaf gen 3

3) VW E-Up, OK, one can dismantle the pack and take individual cells out.

4) Tesla Pods/modules, OK, but high end priced.

Will try to get my hands on a GoPro or similar and do teardown vid's to share here.

Beginning of March, I expect 2 more Mitsubishi Outlander PHEV batteries, with Yuasa LEV prismatic cells,
like in pictures

hi carel,

i think there are many guys who would appreciate if you would offer batteries here in this forum

Carel does offer them as well others. Check under the Marketplace section

Instead of retyping everything, here is a link to some info I found when researching used EV cells..

"Salvaged EV cells index, Leaf, Volt, Tesla, etc"

Hi Carel. I have found a possible source to obtain EV batteries, from the Mitsubishi Outlander and Nissan Leaf.

Question... what in your experience/opinion makes the Outlander YUASA LEV40 the best battery?

From my research the Outlander batteries are only 12kWh, whereas the Nissan Leaf are on average 24kWh. Also,the Nissan Leaf have more cells available to harvest.

I am almost ready to purchase, and am leaning towards the Outlander battery, but just wanted to make clear why the Outlander is the best option. Also, is there a particular Outlander battery pack part number that is better than others?

Depending on how many cells I use I intend to offer the remainder for sale to help cover my costs. I am in Australia so am only intending on making them available to Australian buyers due to the crazy costs for international shipping.

Thanks, Mark

Hello,

Leaf cells are pouch cells
Yuasa prismatic,
I tend to buy priced per kwh battery, in my area Leaf is just overpriced,
I mainly look at Outlander PHEV's, and there are many around,
many more than Leafs

GS YUASA are used in a hybrid PHEV SUV, with a range of only 22 miles, so expect little use/wear on the battery,
in our area it's more a tax thing than going eco green, most business drivers drive on gas only,
all this in contrast to the ev Leaf, much more wear on those batteries.

The pouch cells are contained in this thin aluminium pancake can, the Yuasa has a firm robust prismatic cell,
well I have handled nearly 1.5Mwh of battery since 2016,
with only one cell returned due to a dent in the outer shell, I missed when inspecting.
Nothing wrong with capacity, but client wanted it replaced.

My take go for GS Yuasa, and pay per Kwh

Yes, had noticed the Outlander packs were cheaper, and also noticed mention of LEV50 cells in some packs for sale. Do you have a per Kwh price that I could use for analysis? As right now I have no way to establish whether the price is reasonable or not.

Hello,
Different time zone.
Mitsubishi
Outlander PHEV 12Kwh
LEV40 prismatic cell 40Ah
10 packs in in metal encasing,
packs contain 8 LEV40 prismatic cells, hence the oem name LEV40-8
10 x 8 = 80 cells in total @3.75 V nom
125A max charge 300A continuous discharge voltage range 2.75V-4.1V

Mitsubishi i-MIEV EV 16Kwh
LEV50 50Ah prismatic cell
10 packs LEV50-8 + 2x LEV50-4

A rare car, but if late build model, low mileage, usually not a bad buy

These cells a very nice to use;
M8 male terminals, easy to reconfigure in a multi-S x multi-P configuration
7S x multi-P 24V systems
14-15S x multi-P for 48V systems
80 cells make a very nice 15S 5P 200Ah 11.25Kwh 56,25V battery bank + 5 spare cells,

Pricing;
Take into account what brand new freely available big li-ion cells would cost. (CALB, Winston etc)
Don't buy the brand of the car, or replacement cost of the battery as pricepoint, but Kwh
Water + fire are deal breakers, inspect car, see photo's, Mitsubishi packs are very easy to dismantle.
(be safe!!! unplug car 12V system = controll on pack contactors, take out safety plug on top)
M10 bolted + makita powertool < 15minutes to inspect inside pack + take voltages in yard
(Nissan Leaf: top-lid is glued, and takes about 1 hour + it is destructive)

target pricing should be about 150/Kwh or way better, buying volume.


Think on how to transport, lift pack, store pack on your premises, before you start.
If shipping, build crate on pallet, find ADR compliant trucking, fill out DGD documents, get MSDS, uncoded stickers un3480.
Lot of work but doable, in my area Northern Europe, my trucking company, extra cost of ADR compliant shipping is 35 per pallet.
Very little extra that convinces me to abide the Law.
