Re: jonescg's home battery storage system

Hmm, might need to pull the A/C apart before it gets too cold and take a look. It might be possible to source a 3-phase VFD from a larger unit and adapt...

Re: jonescg's home battery storage system

I was wondering if it's possible to run my single phase, ~3 kW air conditioning unit on three phase, and if that would help spread the total load across all three phases of the hybrid inverter's output. The A/C unit is a Fujitsu DC inverter type, so it's after a ~340 V DC bus (I assume). Would it no...

Re: 4Springs' Brumby

I'd coat it in Kapton tape, or at least some kind of contact adhesive, and make sure that you put a layer of something with a bit of give, like thin EPA or double-sided tape. Ideally you would glue the cells in position, but if you want the option of pulling them apart again, these would be the leas...

Re: 4Springs' Brumby

Yes I certainly wouldn't be packaging pouch cells against bare metal, especially not where it might rub. The pouch itself is a composite of aluminium and polymer, but the polymer is vanishingly thin - and effectively peppered with microscopic pinholes. Any moisture or humidity that works its way in ...

Re: 4Springs' Brumby

The road is a brutal environment for cells. They really need to be well protected, snug, and unable to rub of fret against anything. Or reside in tension - eventually something gives way, and the opportunities for cascading problems start to pile up. Likely there was a leakage current to chassis? Di...

As the 60 Ah cells are not an ideal fit ,would it be better to use them as a standalone system?
https://www.relectrify.com/
How much does a set of the 93 Ah cells cost? How much work to fit this set into an iMiEV?
I was quoted USD$75 each for the 93 Ah cells.

Re: Aftermarket iMiEV battery upgrade project

Roger paid $7600 for the 60 Ah cells about 5 months ago. An additional ~$3000 has been spent on enclosures and copper buslinks to suit.
Pauline was quoted about $4000 for a trade-in some time back too.

As a high voltage home storage battery they could be good.

So an unfortunate turn of events has meant that Pauline will need to sell the iMiEV. She is unsure what the best approach is; finish the battery swap and sell it as a modified vehicle with an unknown future, or put the old battery back together and sell it as a 80 km range EV with no question about ...

Re: jonescg's home battery storage system

OK looks like they can be tied, if they aren't already tied internally. I am intrigued by the AC wiring though. It would seem to me that the MPI10K inverter is basically a solar/battery off-grid inverter which features a grid connection so that it may export power once the battery is full. The MODBU...

Re: Aftermarket iMiEV battery upgrade project

Thanks - I hope to make some more progress this weekend, as I wait for a few more parts and fixings to come in.
Personally I think the 93 Ah cell replacement approach has far more merit than the one I'm taking with this vehicle, but we're here now, so we best finish it.

Re: 4Springs' Brumby

It does need a solvent to solvate the ions, yes. But even humidity in the air will do that. If there's free liquid anywhere it's all over red rover, but even mild humidity will find a way.

Re: 4Springs' Brumby

Yeah, aluminium and anything other than aluminium will set up a galvanic reaction, and iron is a good candidate as it's further down the reactivity table. Alminox is good for any aluminium + other metal corrosion retardation. Not an inhibitor, but a slow-it-downer. Nickel and copper are well down th...

Re: 4Springs' Brumby

Christopher - that electrolyte contains LiPF 6 which is not corrosive itself, but reacts with moisture in the air to form hydrogen fluoride, LiOH and PF 5 . These most definitely are corrosive towards both iron and aluminium. I'd say you've pulled on the tab a bit too tight :( I had no idea this cla...

Re: Aftermarket iMiEV battery upgrade project

To be honest the concept of an M4 screw into a bit of aluminium is sound - there should be more than enough contact and pressure. The problem is the really bad job they did of tapping threads - clearly done by machine with little care and attention.

Re: Wanted - CHAdeMO socket / charging port from a wrecked Leaf or iMiEV

I'm sure a Japanese (or even USA) wrecker will have something. Auctions for wrecked EVs do come up from time to time but you're left trying to find a home for all the other parts.
Which kit are you going to install? I think only Orion BMS is currently set up to play nice with Chademo.
