you will get rid of the other when you fix the 0.00

 

How do I do this?

 

Agree with Jaime you need to crack open the pack and confirm.

Logging: You set it up in torque pro. Go into the settings. You'll figure it out.

You already stated you know you need to replace the modules in your pack. 1.7V difference in that screen shot pretty much guarantees it.

Additional data:
Voltage taper from high at ends to low in middle
Voltage is evenly spaced between the high and the low

IMHO, 99.999% certain you need to replace all 40 modules. I don't see a point in logging a discharge other than going through the steps to attain the ability to log them.

 

Find the issue. I am repairing the connection now and I am also taking initial voltage readings vs 120 sec on a 0.3 ohm resistance. I will get the logs from torque after its all back together

 

What's the story with your pack? Are those nickel bus bars?

I'd save yourself the 80+ minutes of wasted effort. Your block voltages already tell the story. You need a new pack.

 

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.

 

Must be the angle or the lighting. They don't look copper colored.

You've confirmed your entire pack is scrapped and confirmed the numbers reported in Torque Pro.

The Chinese modules are awesome if you like throwing money away on something dramatically inferior to the original that should fail in 1/4 to 1/3 the time if you're lucky. I bought and tested 5 of them, and they are truly garbage... just like the Chinese "D" cells for Honda I've tested. If you actually believe ANY of the products on Alibaba have a meaningful warranty, 1) they will try to blame your BMS for failure and 2) they will require you to ship bad modules back to them, which costs more than the modules themselves.

List on the pack is around $4K, but it seems that you can get them for around 3200 if you hunt for it. Do what Jaime did and buy 2X low mileage Prius C packs of similar year and mileage via LKQ online and spend about $2K total for something essentially as good as a new one.

 

I think i did the log file correctly but honestly have no clue.

 

All codes are cleared and auto stop works again. Thanks to everyone four the help. Now to find a battery.

 

Nope, but now we have your exact time and location.

You have to flag the PIDs you want to log. You just logged the default time, speed and position. Recommend deletion.
