^There's not much I could do to test - besides trying it out, which I definitely would be curious to do. I'll PM you my address, you PM where to send the shipping payment. Sound good?
Not exactly, but I don't see how that would change anything I've seen thus far. I've seen no charge drain on the OBDIIC&C, for instance, no 'negative current' in the Bam parameter... How many miles do you think I have to drive until I definitely should have seen what you think you saw?Have you attempted to recreate the fail? That is driving on flat ground at constant highway speed for some distance without IMA assist...
The most important things to focus on are a lower pos recal threshold and the automatic 5% discharge.That’s quite a bit to digest.
From what I've seen thus far, I think that could be said. An unbalanced pack means some cells, at least one tap, is more charged than the others. The BCM will stop charging when the most-charged tap reaches the pos recal threshold (call it 16.7V here), leaving the other taps at a lower charge level. So, we start with a lowish, uncertain pos recal threshold, then we throw in imbalance that leaves most of the taps at an even lower level... I think this BCM would be more sensitive to imbalance and would probably have less ability to correct it.It sounds like the late model BCM doesn’t like packs that are unbalanced more than earlier BCM units.
Aftermarket cells are a little different than OEM. I don't feel nearly as certain about their behavior as I do about the OEM cells...The battery pack in question was purchased new from Bubble Bee I guess 3 years ago and installed in my 02my CVT Insight. I probably ran it in that car a year until I wrecked the car....
I've heard that before. It would definitely make sense. No experience with it though.Still the car is not quite right. Is it possible an under-performing ICE could effect how the IMA manages the pack and could be why it wants to uses assist so much more?
Sources say later Insights used Civic cells, and Civic cells are different from 'Insight cells'......I've read some of your posting concerning this A03 BCM. It seems you've come to the conclusion the NiMH cells originally installed in my 2006 are different than earlier year vehicle cells and the same as Civic. It never occurred to me cell chemistry changed from earlier vehicles and could be the root cause of the failure.
I know very little about Bumblebee packs or other aftermarket packs. In theory, since the A03 is meant for 2005/06 Insight sticks or Civic sticks, if the A03 didn't work right with your BB pack it's probably a decent guess that the BB pack is more like older Insight packs... Or maybe your BB pack had issues...Currently I'm using the OEM 2006 battery pack with an earlier version of the BCM and all appears to be okay. I never ran the A03 with the 2006 battery pack. When I received the vehicle I immediately installed a Bumble Bee battery since it was less than a year old. Evidently it was a mistake not to change the BCM at the same time.
Yes, absolute level, real charge state, or at minimum the charge state shown on an OBDIIC&C, not 'the bars'...I may want to re-install the A03 into my vehicle to see how it works with the 2006 battery. I think when you posted that the A03 maintains the battery at a lower charge level, you're referring to the absolute level as provided by a scan tool versus the relative charge level provided from the vehicle's dash meter display.
Not really. I only used it with my 2002 Insight pack. I thought the way the A03 BCM charged that pack, with a low pos recal threshold and generally forcing usage at the bottom-end of the charge state range, might have been done on purpose. That usage pattern fit with my pet theories about low charge state usage, which I think can be good, so it made sense to me. BUT, it turned out that it was all about the different cells, older Insight vs. later. The A03 BCM will under-charge older Insight packs; for example, when I used it I never saw a charge state above about 50%...I think you determined the purpose of this lowered charge level improves efficiency and perhaps battery life as well. But only for the later battery....
I never tried it with anything other than the 2002 Insight pack. I didn't experience any of the issues you had, probably because my pack was in good condition or because you were using an aftermarket pack. At some point people complained of weird charging issues/state of charge issues with aftermarket packs. I don't think there's ever been much resolution around that. In general it's common IC knowledge that 'the aftermarket packs' have slightly different voltage characteristics, so... I don't know, there's been changes with aftermarket packs, I think newer cells are different. I don't like to think about aftermarket packs because it's all shrouded in mystery...1) Were you able to run the A03 using the latest G1 Insight battery and were there any issues?
2) Did you have issues similar to what I experienced when running the A03 with an earlier battery?
