Imiev drivetrain is a good one.
Once the controller and charger etc are in there won’t be any engine bay for batteries and you won’t fit a whole imiev pack in the boot though.

I know of a wrecked imiev that went for less than $2k complete

I MIEV sounds interesting...
Parts from a wreck?
Japanese import?
Parts import?
Oddly I have been looking the last couple of weeks and haven't found anything worthwhile.
The Japanese import would be of some interest as they have the Toshiba SCiB batteries due to the colder climate.
It would be cheaper to find a write-off in Australia rather than importing parts.

Don't forget if you want the miev/minicab motor it is setup for 300+ volts.

OK so 300volts.
What are the real world implications of 300V?
More batteries?
More available GO GO?
Need to stick with the original controller and electronics?
Some of the conversion companies have suggested 96V, but didn't give a reason...
I'm a noob remember.

Stuff I've read indicates that the Minicab miev seems to have a lower kW rating than the imiiv. Yet also says they share all the same equipment. (EV wise)
Is this so, or a case of controlling the same motor differently?

I can get a Minicab imported for around The $9k mark.
"Assuming" I can use everything from this to convert into a mini, Is there any inherent problems with Imiev equipment that might be incompatible or problematic with regards to repairs or replacement?

You could have a look at some of the i-MiEV discussions here. There are issues with components being VIN-locked and having to be programmed by a Mitsubishi dealer. May not be an issue if you keep everything and never have to replace a component. Or may not be an issue if you can bypass the relevant components and use something else.
I think both varieties of i-MiEV are rear wheel drive if that matters.

There is a chance that the BMS will throw an error if it doesn't see the battery for a period of time, probably some months. That should be fine if you have the appropriate error clearing equipment, but these can be hard to source, and the Mitsubishi-specific firmware can be even harder to source. But people have done it. You might be able to avoid this problem if the conversion is quick, or at least the BMS to battery connection is quick. If it has to be extended for whatever reason, perhaps arrange some temporary wiring so that the BMS sees the battery, even if they are in separate vehicles.

I am looking to buy a wrecked Imiev and I am unsure of the usability of the high voltage motor/controller.
Also the factory electronics and anti theft shut out that all modern cars use has me concerned.

Is there any way to run the 330 volt motor from an imiev at a lower voltage?
or make up a conversion plate to fit a lower voltage motor to the transmission?

My preference would be to utilise about half of the batteries (reconfigured to fit in the Mini) to run a lower voltage motor/controller.

Yes and yes, you would loose a bit of power and it would take a bit of research. I recon you should use all the batteries mounted in the front and make a rear wheel drive mini. You wouldn't need the transmisson. That would be cool.

Thanks,
Prius off the list!
Because of the lack of room or the poor EV only range? There are a lot of lithium add-on packs and DIY upgrades around and being so cheap to buy the whole thing you could just transplant all the gear into the mini ..... then you could post photos so I can look at doing similar in another vehicle :lol: They get along quite well as a full bodied Pruis so in a light weight mini body I reckon it would fly .... if it fitted in the hole of course :?

Back to the Prius idea, way out in left field but I thought I should throw it out there anyway. My PHEV Prius has a 10kWh plug in battery pack as well as the 1.4kwh traction pack. The PHEV allows for the option of "ICE Kill" so it will drive as an electric only vehicle. If just the transaxle/2 electric motor part was used and mated to an additional electric motor designed to take over past the limited speed the electric transaxle can deliver in place of the Ice engine it would make a great all electric drive platform that is very cheap. The sensors associated with the ICE engine would probably need to be spoofed, but maybe one in ICE Kill mode that part of the computer doesn't even look at the ICE sensors.
