Cost to replace an i-miev battery?

Citroën Service Box lists the original 2011 C-Zero battery (same as iMiEV) as 81,000€

Hi kiev I did a search and found your posts on the battery replacement. Luckily I don't need a new battery but I did asked about the price at the dealer. They quoted 100,000 Dkr. which is about $15,000 US. There are still low mileage iMiev/CZero/iOns around for much less.

22000 euro for bateri

Ocober 2019: replacement battery for i-Miev from dealer in Canada is CAD$29000 plus 15% sales taxes.

yep, ridiculous that Mitsu hasn't budged on the price of replacement batteries during a period in which the global cost of EV packs has fallen from around $500/kWh (2010-2012) to approx. $140/kWh nowadays. This is getting serious as our 2012 batteries fall off warranty and begin to finally show greater than 20% depreciation. Mitsu actually dropped the I-MiEV price by 35% in the early JDM versions due to the "rapidly falling cost of batteries", and that had to be one factor in the 20% price drop on the 2014 model versus the 2012 premium edition, given that it had most of the same features...
c'mon Mitsubishi, we got excited with the OBC warranty extension, in recognition of the only significant design flaw on this vehicle. How's about stepping up with some better battery options for extending the lives (or EVen the range) of our beloved bubble cars?

Well... Here we are in 2020

And here I am with a 2010 I-Miev, with only 27000 miles on it, that can only just cover 25 miles on a full charge!
So this thread is more relevant now that it was when it was first posted but there is still no good news regarding official replacement costs I see.

I have an OBDII dongle and a metered plug on their way to me so I can gather some data and figure out what's going on with the pack I have but, regardless of mileage, at 10 years old it could just be regular degradation. We'll see...

So I'm looking at 18650 3.7v 5000mAh Li-ion cells. Using these would of course mean assembling my own battery packs from scratch BUT... To purchase just over the required replacement capacity for the standard I-miev, the batteries I have found so far would only cost £660 in this format. That sounds too good to be true.
Am I calculating the capacity correctly? Is 5000mAh = 5Ah? Is there another factor I'm not considering?

EDIT: Never mind, I'm likely looking at FAKE cells... smh.

5000mAh (5Ah) 18650 doesn`t exists.

But. cappacity isn`t everithing.
Odher parametters is important too. Maximum charger and discharge current.

I find only one 18650 cells whot can yous in ION because have hign charge/discharge current is Molicel.

But better fit in LEV50 dimension 21700

Thanks for the advice. I did edit my post having realised I was looking at fake cells.
RE: your 21700 link. To replace the entire battery pack of an I-miev, equal the cars original capacity, with these would cost around £4,250 just for the cells. This is pretty good.
£5000 seems to be a consistent figure wherever I look and which ever form factor the (genuine) batteries come in.

Battery prices are meant to be falling rapidly. Perhaps high demand is what is keeping the consumer retail price up.
Either way, there doesn't seem to be any substantial support for the battery packs for these cars yet.

Posting this thread here as we're likely going over a lot of old ground already covered otherwise.

What we're really waiting for in 2020 is this fated reduction in battery cost to filter down to us lowly home gamers.

 

[Enginerd]

20 x 21700 LG M-50 cells ordered and on their way for initial testing.

This is enough for a 100 Ah cell, double the capacity of the LEV-50 used in the car currently, lighter and in the same form factor.
If I can get it to work, a full pack (at the price I paid for 20) would cost £5200 just in cells!! but give the car a real world range of about 170 miles.

Of course I could assemble replacement cells with the original capacity for half that initially, £2,600 or less.
Could even design the packs to be upgradeable at a later date by doubling up on cells.

This will definitely be a fairly expensive project... Still doing it though.

Anyone got first hand experience of a decent spot welder to put batteries together with?

Looking at this at the moment...

Yes. I have a KWeld unit. Made in Germany and works really well. I bought it to build an eBike battery. Two pieces of advice: make sure the charge/discharge rates on the cells are compatible with the car (125 amps on quick charge, up to 150 amps discharge), and make sure whatever you use to build the packs, be it nickel strips or something heavier duty, can handle the amperage. The mistake I made with my eBike pack is that the strips are too thin and get warm under load.

For best results, purchase the KWeld, KCap, and KSupply modules. The KSupply is made for specific power supplies, but can take any 12 volt source (I use a small lead acid battery as a source, but the KCap does all the work).

Very cheap solution, not verified by me (german language, but you get the idea): https://www.youtube.com/watch?v=hWTkI6_OeNc

That is a very quick and simple spot welder. Was there any sort of resistor underneath the clear RTV and black tape, and what was the purpose of the 2 tiny wires on the supercap?

Here's a couple of spot welder links also:

It is just a battery connected in parallel to the supercap. The wires were intended to check voltage, but he did not use them.

I have heard good things about this kit before, along with some damning reports about the Chinese units doing the rounds, so I've ordered one. Thank you for posting the links.

Good luck to you, Enginerd! The similar Aussie effort has stalled, and now that I have a 75 mile one-way commute, MR BEAN in on greatly reduced duty, only doing about 250 miles per week of wifely driving, while I do that much per day on a 27 kWH Kia SOUL and my company car, a z2012 LEAF that we have upgraded to 40 kWH with an 2018 battery.
