Re: 2010 Imiev charging question

I suspect he meant "Level 2" (i.e. public AC charge, not home charging), rather than the phyiscally different plug (as the 2010 imiev's don't have the ability to communicate with the EVSE even with the right plug)? I'm interested to see how you go. I'm planning to get a wall mounted EVSE here for th...

14.5mm? Is that a pouch cell?

Re: iMiEV charging, J1772 testing

Edit: the pilot processing hardware may be missing from the 2011 chargers, but then how can that mob offer a harness that fixes the problem? I think with the modified harness, it's just enough to convince the EVSE a car is there and to close a contactor. I don't think the car then reads the control...

Re: iMiEV charging, J1772 testing

That the brick reduces charge current on MY12+ but not 2010s tells me that the 2010 charger ignores the signal from the EVSE about how much current it should draw. As I understand it, all the 2010 mods are just enough to fool an EVSE to turning the juice on. They don't make the charger smarter, but ...

Re: iMiEV charging, J1772 testing

I wouldn't be able to set a timer accurately enough to hit 95%, given the length of time needed also varies. I did briefly play with a raspberry pi connected to the OBD port to monitor charging and somehow trigger a charging stop but I could never reliably get it to read the messages and track charg...

Re: iMiEV charging, J1772 testing

I reckon you could get to 120 or more by leaving your location and descending to a much lower altitude with regen (but should you ever do that??). We do this on our work commute, the regen slowly tapers off as the battery reaches max state of charge. I'm not sure it is great for the battery, and I ...

Re: Nuggetgalore's iMiEV charger failure

I did at some point come across a recall notice for the charger issue on Mitsubishi Japan's website. Google translate indicated it was because "capacitors may crack"... To me it sounded like there was a problem in the chargers prior to the recall that is suspiciously similar to the problem in the ch...

Re: Nuggetgalore's iMiEV charger failure

I don't know exactly what grounds they agreed to replace it, but quite likely the main factor was that the charger had been replaced in a recall about 18 months before the failure. My charger failed within 18 months of the recall replacement, and my suggestions to the dealer that it should last at ...

Re: Aftermarket iMiEV battery upgrade project

As a quick test you could wire in a more readily available fuse holder with eyelets, and either stuff it under the inverter cover or just leave it hanging out. Obviously longer term that's not vibration proof and might have insulation rub bare.

Re: Aftermarket iMiEV battery upgrade project

I was thinking it's only 3 years lifetime at one cycle per day, or four years for one cycle per weekday.

Although I guess our imievs capacity is more like 35ah now, so what is a full cycle on the old cells would be a half a cycle on 70ah cells.

Re: Aftermarket iMiEV battery upgrade project

Max voltage 4.2, and the imiev charges to just under 4.1.
Looking closer they are only quoted for 1000 cycles at 0.2C rate... So you might have to be quite gentle with them.

Re: Aftermarket iMiEV battery upgrade project

I have some photos from the process of replacing the blown capacitors in our charger. Unfortunately I'm also the originator of the precharge resistor thread, as we got some wires crossed when putting it back together. It's actually relatively easy to remove the charger, definitely a lot easier than ...

Re: Aftermarket iMiEV battery upgrade project

I agree that it is best to sell the car unmodified, unless it is sold directly to an owner who is taking it on as a project. Then I guess hope to find a good buyer for the cells as home energy storage. They'd be a lot easier to put together than thousands of 18650s. If there was another test project...

Re: Aftermarket iMiEV battery upgrade project

If I'm not mistaken these are much shorter (115->85), about the same width (44->43), but slightly longer (171->173)?
I supposed if there are 2mm leeway on the width, it should be possible to pack the rest of the space out. Presumably there is a weight saving along with a capacity gain!

Re: Aftermarket iMiEV battery upgrade project

Cells of the same dimensions would really help - regardless of the capacity. The samsung SDI 94Ah cells are not far off. Would definitely shave them down to 80Ah to get a cell the right dimensions and be really happy. One thought a friend put to me was to construct an entirely new subframe and pack ...

Re: Aftermarket iMiEV battery upgrade project

I can't find the 78Ah model you refer to, but those dimensions seem ideal, and 78Ah would be a good step up without wasting too much if the BMS only recognises 60ah.

If the monitoring units are not in the pack, I think that kills my plan of preparing the pack ready to swap so I don't have to take the car off the road for an extended period. Yes, it would definitely be better to get something closer. Not at all urgent - but I think I might really struggle next wi...

A battery shell would be exactly what I'm after! I'm assuming it's located in WA?

When you say none of the BMS is in there, does that mean the cell monitoring units have been...

Re: second hand imiev battery

Ahh yes that makes sense, it would give a basis for comparison of how much the range is reduced by battery degradation, and how much is driving conditions. Or if buying a battery for its cells, rather then just the frame, packaging and BMS, it would only be worthwhile to get a higher capacity pack. ...

I tried evbatmon once quite a while ago, I think it was still under development, and it didn't work with either of my OBD adapters. It's not really material to me what the BMS thinks the Ah reading is though - only that I have enough range to get home, and if I can run the heater while doing so or n...
