Re: P0B3D and P0A2D
I assumed they were the original bus bars, they were corroded when we first got the yukon at 125k so I took them all out and cleaned them with a wire brush.
Too late on the other, I did test them as 14.4v blocks though which saved some time. Blocks 1,2,3,19, and 20 showed a 1.30-1.31v drop each after two minutes, blocks 4,5, and 18 showed 2.69v, while the remaining showed a 3.18v-3.32v drop 🤮. I'm putting it back together now.
So what's the going price at gm for a new battery? $3k? Has anyone tried the new cells on alibaba they are about $40 each and made with some of the best child labor in the world.

Yes. Please waste $120 + shipping so you can save temporarily spending $1000 on the promise of destroyed modules being able to provide emergency power in the power outage. TOTALLY makes sense. Heck. I don't even need a core, but I want one now!

Re: P0B3D and P0A2D
including lodgging car rentals etc.. that would bring the cost over 1k
i doubt i would be able to return the core locally anyways.. now if one could then yeah go for it
it was 140shipped for 30 cores btw

Re: P0B3D and P0A2D
S Keith, have the prolong units been able to rejuvenate the yukon batteries or by the time we see the failure of the pack the cells are too far gone. I have a gen ii prius in the garage so a tool investment might be worthwhile.

Re: P0B3D and P0A2D
that is incorrect once ULTRA Capacitors reach close to what the current pack(1.86KWh) is at the problem will be solved... it will still need a battery parallel with the ultracapacitors for it to function correctly but not as big( just so it does not go flat etc..)
Maxwell had 2500F 3v capacitors back in 1996
there was also prototypes of 3v 4300F in 1995/6 from Asahi glass but has not been any updates since 2003 ( most likely bought or paid to STOP R&D, by BIG oil.)

Re: P0B3D and P0A2D
Wrong.
A very smart gentleman built an ultracapacitor pack for a Honda Insight. It had roughly 1Ah of capacity vs. the IMA battery capacity of 6.5Ah. That was enough capacity to allow it to perform acceptably.
It was $5500 for the ultra caps alone. His many hours into a spoofer and programming aren't included in that.
The idea that caps will somehow replace hybrid batteries is pure fantasy. Lithium battery technology is improving too rapidly for caps to keep up, and caps will always have a low power density compared to batteries. There is ZERO financial motivation to replace aging NiMH packs with anything but more NiMH packs.

3V capacitors? You will need to have about 130 of them in series to survive intermittent 409V spikes in cold starts.
Do the MATH on series capacitors! Then see how many you need. Than how big it will be.

Re: P0B3D and P0A2D
sorry then why is trump administration rolling back fuel mileage requirements as well as emissions output..
Chevron bought patents and controlling interest in Ovonics,(NiMH patents) the advanced battery company back in the EV1 days and BASF bought it out before the patents expired in 2014 ..
if it is spiking to 409v no wonder the batteries are getting blown out quickly.. that is a design flaw did you get the software update before? there was a software update for the reprogram the electronic brake control module, battery energy control module, hybrid powertrain control module, engine control module, and transmission control module, and replace the high voltage circuit impact detection (HVCID) 2008 only(v1814-08119)
but that is wrong the DOE says 363.7volts as the maximum charge pack voltage that would put it at 9.0volts per cell

1.51v is the correct value to charge a NIMH battery cell.

Re: P0B3D and P0A2D
The Trump discussion is a whole different topic. In general he is un-doing anything done by his predecessor on regulations.
Do the Wikipedia search on Cobasys to learn about the joint venture between Chevron and Energy Conversion Devices ( Ovonics) before going conspiracy theory on Big Oil here.
The high cell failure rates tend to be from hotter climates. It takes well below freezing to increase the chemistry impedances in order to get the spikes.
