Replacement Battery Options for 2012 i-MiEV?

Post by DanMiatt » Sat, 29 Dec 2018, 06:16

Hi,

I've done 110,000km in my i-MiEV over the last 6 years.
The range has dropped, as you'd expect, so i'm considering my options.
Going back to ICE isn't an option.
Upgrading to a Kona or Niro is looking good.
Before that though, i'd like to explore battery options.
Mitsubishi quoted me 15k to replace the battery.
I had another quote for an upgraded battery (17.25kWh pack, weighing 50kg less than the current battery), but that was over 20k
I've been told it's possible to get it done for closer to 6k. Can someone suggest where i can get this done?
Alternately, are there any other upgrade options?

Hi Dan,
Where are you based?
I'm going to be re-packing an iMiEV battery with higher energy density cells for a chap here in Perth, and it means doing a bulk order of cells from LiYuan. The cost will be about $13,000 in cells, but you will effectively have a 200 km range iMiEV.
Cheers,

I'm in Melbourne. 200km range is extremely tempting, that basically means i can get anywhere in Melbourne.

I could potentially freight the car over to you.
How long roughly do you think it would take?
And how would i go about getting it serviced over time?

Or is there someone in Melbourne you could send the cells to, to do the install?

Well let's take one step at a time - I need to get the first one done before I can say with confidence I could work on your vehicle.
The issue won't be making it fit, although that will have it's challenges. The difficulty will come with the iMiEV BMS dealing with its new-found battery capacity.
My plan is to get an empty battery enclosure and re-package it. Then when I am confident I have the same thing as before, just with added capacity, I can do a quick battery swap with an old iMiEV. This minimises the amount of time the vehicle spends off the road. If that goes smoothly, I will have another battery enclosure to repeat the process with.
Hopefully the BMS doesn't have any issues, but we've seen a few iMiEV battery replacements here in Perth (like for like) and they still had issues with the vehicle integration.

A 15k quote from Mitsubishi seems reasonable: https://www.amayama.com/en/part/mitsubishi/9450a021

However I'm hoping there are better options when out imiev doesn't have the range we need anymore. My interim plan is to get a charger installed at work. Beyond that I'm quite interested in higher capacity cells, but I think I have a couple of years before I'll need to do something.

I didn't realise like for like cell replacements had been problematic?

Yeah, Larry Mudd and Joseph's vehicles had some integration trouble, but they have since been resolved.

Ok cool, please keep me updated with the progress. 200km range would be nice!

Just trying to find some info on the replacement troubles and how they were overcome.

I think Larry's was a whole pack replacement? From what I can understand of it, the troubles were the car firmware not being compatible with the pack firmware. This makes me think you wouldn't see this problem if you kept the existing pack BMU and replaced the cells. But it doesn't preclude the BMU not liking the cells.

Also looks like Larry's pack replacement cost about $6K. But the prices have now doubled?

Yes, the fact that the BMS on the new pack was different to the original may have been an issue, but it will be the same problem in my case as I hope to use the old one from the battery I am upgrading. If we have the time and the different BMS plays up, we can always swap the new one across.

The new battery packs have LEV50N cells which require software updates to the BMU and then calibration with the CMU's. Nicely packaged on a CD but useless unless you have an MUT-III diagnostic tool and the applicable modules for I-Miev.

A related question: I have two Car service Manuals discs
MITSUBISHI iMiEV IMIEV 2009-2013 that came with the car I bought (2010 model)
and MITSUBISHI iMiEV IMIEV 2009-2012 that belongs to a friend wit an 2012 model.
It appears one needs internet Explorer to access the manual, we downloaded all the data but cannot access it.
Has anybody been able to hack these discs?
I am interested to get the instruction to remove and replace the battery pack.
Watching some videos it can be tricky if little details are missed.
An other option is if some one has hard copies of said instruction I am willing to pay for a set.

Interesting - I just noticed this:

It looks like the maximum capacity is set to 60 Ah... Might be worth sticking to a 70 Ah cell then :?

hmm... Depends on what it does above that value.... if it overflows to the negative it would certainly give the fuel gauge and guess o meter a hard time.

But it might still drive OK until it hits a voltage limit?

I wonder if a shunt trick could be a work around. I know in other vehicles the battery ecu measures current independently to that of the mc, for the purpose of soc calculation. The system may not check to see if the two values agree.

You could use two high current 50mv shunts to act as a current splitter, halving the battery ecu current reading

Thanks for the link.
Plenty of useful stuff in English.
Unfortunately my Russian is non-existing.
I wonder how much information is in the Russian section?
A friend of mine thinks he may be able to get our discs to read, no promise though.
The problem appears to be an internet explorer issue.

I'm fairly sure that mmcmanuals site is a copy of what is on the imiev service manual disks, adapted to not require internet explorer and be compatible with other browsers.
I mucked around with the disc files bit and got pages very similar to what is up there.

That site is also good for other mitsubishis, not just the imiev

i agree, the disks and pdf's are no better than the russian website!

Well if the 100 Ah cells don't fit, there's a good option for two 42 Ah cells in parallel.
Will need to try and lay them out, but there should be a way of making it work. Even if it means remote fly-wires for the BMS.

I found this website selling what I assume to be exactly the same as is on the disk but in PDF or html format.
I think it might be worth getting if it really has all the nitty gritty available but not if it is just the same as the rusky link.
Anybody has bought from them?
