Re: Feb 2012 Miev with Pack Trouble at 40k miles

Because Kenny mentions a faulty cell, I add here that I manually balanced the cells before putting them back , my scanners (i909 and also Vident) agree max cell is 3.82 V and min cell 3.81V, so not an obviously faulty cell. All other data read on the BMU appears to be normal. What is this leakage a...

Re: not charging my iON, cell or CMU or BMU problems

Not as much as I hoped unfortunately. Ah capacity after doing a recalibration only went up from 32Ah to 34.5Ah, and after about 9 months use it had dropped to 32.5Ah again. This is because while I replaced the worst cells there were other cells which were not quite as bad which now become the worst ...

Re: not charging my iON, cell or CMU or BMU problems

I think so. But maybe the cell it´s ok and the read it´s the problem . Because we can see the voltage for the LTC job and has memory marking a bad cells. . Did you test the bad cells out of the battery after replace? I tested their capacity after removal yes, and they were much lower than other cel...

Re: not charging my iON, cell or CMU or BMU problems

Pepin, From what you describe you have a faulty cell, not a faulty LTC chip. If the voltage drops by much more than other cells when accelerating vs coasting the cell has high resistance. Another way to confirm high resistance is to monitor the cell voltages while DC rapid charging the car from belo...

Re: not charging my iON, cell or CMU or BMU problems

Great work, it looks like you have a really good pack, not to worry about 10mV, that would not damage the CMU. the pack has 35A-hr capacity according to your screens and all cells within 5 mV from this Canion screen. The Laef uses SOH but not the Mits. So 35A-hr from 50A-hr its only 70%. I do not t...

Re: Hi everyone....have two 2012 I-Mievs.....need help....

yea i've always thought the cost of the scanner was like one visit to the dealer, and anytime it can be used to save a trip is money staying in your wallet. i don't think that SRS codes can be cleared for some reason, likely liability and safety concerns. There is lots of airbags in these cars. Did...

Re: hobdrive - and i-MIEV ion zero, show electronic control units, reset errors

In that case, I think I’ll try and scrounge an old Android tablet to leave in the car, rather than roll the dice on a new adapter. I'm using my adaptor (first with Canion and Hobdrive, now with Leafspy as I now own a Leaf) on my son's Amazon Fire HD 8 but it's a bit of a pain as Fire OS has to be h...

Re: No READY. P1A15 error. Condenser charge timeout.

i hope the Laef works out well for you, they are nice cars--almost luxury compared to the triples. i fixed one up for my daughter and she is loving it. Take care, let's hope we can all survive this virus and lockdown mess. Thanks. Yeah there's a lot to like about a 30kWh Leaf, it does Kinda feel li...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Recuperation means regeneration yes. Most German language speaking EV drivers seem to prefer this word even when speaking in English. :D I agree with what you've suggested - mismatched tyre sizes will severely limit regeneration, as will being fully charged. I can't off the top of my head think of a...

Re: End of the line...?

Piev sent me a link to asia nikkei automobile business section that Mits would stop making the miev...sad to hear. Wait, they were still making them ? I thought they stopped a few years ago now. Not surprising though. Not only is it no longer competitive, Mitsubishi are really struggling. They're c...
