Separate names with a comma.
Assuming this is the case, sorting based on "capacity" (putting weak cells at the end, nearest the fan), may not be a bad option, though weak...
I think I may have maybe figured out why some people do the "pairing with opposites" style. Based on this it seems that modules tend to fail in...
According to How to measure capacity of a 3S NiMh battery? - Page 1 the "ANSI" procedure for NiMH is to basically charge to "full", then discharge...
from [MEDIA] maybe the inverter overheated so the car shut down off or something weird?
Found a dude on ebay that'll match capacities, FWIW... :)
I think I'm kinda getting what people are saying about "whack a mole" which is basically that if one module fails, possibly the "next worst" could...
Nice. What is a 0.3 delta here?
Sure enough "temp1" is the one farthest from the ecu, i.e. closest to the fan in my 2007...
Looks like "farthest from ecu" is white, midde is black, closest is blue. Based on Torque settings when changing battery module | PriusChat white...
Anybody have a feel for max amps you "could" or "should" charge a module at? Assuming its in the pack with small fan blowing on it... Thanks!
Gen 2 is good except sometimes consumes oil, you could ask about it...
For my most recent cell loss, initial voltage readings were [ecu] 1. 7.54 2. 6.35 <- bad 3. 7.51 <- degraded 4 7.58 5 7.59 ... and a cell I lost...
Theoretically the prolong charger is the same process. That is how I calculate voltage drop, and it seems pretty good. Calculating capacity...
I can confirm some ebay sellers seem to measure capacity from "full" down to something low like 1.0V (which can inflate it it by like 3.5K...
So the two at 7.4 started at 7.9,. from the original post? Curious...
I'll collect random reports in this thread. Here's one of somebody losing a cell in the middle of the pack: Changing bad module on hybrid battery...
Just for fun I looked for images of "Dr. Prius" to look for temperature readings of the batteries and sure enough, usually temp1 is coolest, temp3...
Thank you for the replies. I guess this explains why the red triangle of death shows up with 1V low on a block, maybe it's trying to detect a...
I've had one fail right in the middle. Another near the ECU...lost cells I think.
I'm looking for any patterns in module failure. Is it random? Closer to the ECU? Toward the middle? (fan is to the right, the opposite side of...
