Couple things here...... 1) Where did you buy this new traction battery? Dealer? Other? (will help us understand what we are dealing with) 2) Did...
When you start the cycle are you holding the start button on the screen where it shows DCHG>CHG 3? Also did you go into "user set program" and...
I'd like to say a big thanks to all the folks in the PC community......invaluable resource and a wealth of knowledge for sure. Couple more funny...
It's official, my issue is solved. Interior is back in and I got a chance to clean everything in the process. The car has had this weak module...
Ok well I have some good news...... 1) I found the problem and 2) It looks like everyone should be doing a load test too when rebuilding their...
Just a report back and Jeff was spot on with the voltage drop. I tested one of my spare cells which had a capacity of approximately 6000 mAh and...
I totally agree.......having tried 5A in testing it was a bit harder on the modules at higher SOC's than I wanted so I dropped it down to 2A and...
I wouldn't go against anything Eric said above since he certainly has a wealth of knowledge we could all learn from. That being said I've had very...
Yes all my modules showed a consistent internal resistance of 0.029 ohms across every bank on the pack (viewed using mini VCI). I bought a...
For some reason I thought the capacity and load tests were different, but hopefully when I test them I will be able to see what you are saying is...
You mean the sensor wires coming off each block? I still haven't had a chance to load test them yet, will need to wait until this weekend to try...
I only did 2 charge cycles on each in most cases since the packs typically went above 6100 mAh on the 2nd discharge cycle when charged to 7000 mAh...
Yes I do have mini VCI and I'll take a few screenshots tonight so people can see what I'm talking about as I drive around. I kept good records on...
Nice to know because after cycling my modules they all seemed to be able to hold capacity well (none less than 6,100 mAh) and they were well...
What did you notice about the bad module vs good ones when loaded? Voltage drop? How much?
Very well said, couldn't agree more. When using mini VCI with Techstream to look at the voltages the key is to watch and see if the same battery...
I agree, given the current state of the rest of your battery pack without question you should be changing out any modules returning less than...
Congrats on a successful rebuild. Did you use my first or second scenario for balancing the blocks? Gen II Prius Individual Battery Module...
I think you'll find you need to do some pretty decent disassembly regardless so it's probably best to just pull it and lay it out on the bench for...
What I did was to cycle each module 3 times D>C at 7000 mAh (first discharge tells you the state of the module coming out of the car, the second...
