Hello! I have toyota aqua 2015 that has a failed battery pack, so i decided to conduct the following experiment to determine which cell to replace and how many to replace (first time messing with a car, so let me know if the procedure is correct or not). First, i cleared the error(P0A80-Replace Hybrid Battery) using a scanner that allowed the car to function as normal for some time. During this period, i logged the following for 830 seconds with steady acceleration and sharp breaking(enough for the regen breaking to work) : Battery block number with minimum voltage Battery block number with maximum voltage Battery Block Voltage,... (from 1 to 10) Batt Pack Current Val(Amperes) So logically, i figured if i plot the battery block number with minimum voltage, i can then determine which cell is causing the car to assert, but unfortunately i am not able to make sense of the data with confidence so any help here would greatly be appreciated.
Looks like blocks 2 and 4 had high voltage for the shortest amount of time. Followed closely by block 10 than block 8 block Internal Resistance readings should help narrow the search too. - see drprius app.
