Single Cell Testing - Suitability Algorithm Part 2
Make sure to read “Single Cell Testing - Suitability Algorithm Results” (Single Cell Testing - Suitability Algorithm Results) to understand more of the background behind this page. In the first iteration, the algorithm was run for all 1379 cells, looking for outlier cells in each of the 7 data types:
Open circuit voltage (OCV)
AC impedance
DC linear sweep internal resistance (charge)
DC linear sweep internal resistance (discharge)
DC pulse internal resistance (charge)
DC pulse internal resistance (discharge)
Weight
An outlier was defined to be a value that was more than 3 standard deviations away from the mean for the given data type. Each outlier was assigned a certain score for each type of test that it was an outlier in. For this revised iteration, a few changes have been made to ensure that more cells can be eliminated (the goal is to get around 900 cells for the final battery box).
Outliers are now 0.25 standard deviations away from the mean.
If a cell has a total outlier score of greater than (but not equal to) 1, the algorithm will recommend for that cell to be removed.
Each internal resistance outlier now has a score of 0.5 (previously it was 0.25). Since the outliers between all the internal resistance tests are usually the same cells, they would have a combined score of between 1 and 2, ensuring that they can be eliminated.
Note that the raw data has not changed between this iteration and the previous one, so the graphs can be found on the previous page.

AC Impedance Outliers
Mean: 0.02577 Ohms
Standard deviation: 0.0009399 Ohms
There is still only one outlier for this test, which is cell 1034 with its ridiculously large 3470 Ohms. This cell should probably be removed.
DC Linear Sweep Internal Resistance Outliers (Charge)
Mean: 0.04124 Ohms
Standard deviation: 0.004323 Ohms

Oddly enough, there were 50 more outliers for the charge portion than the discharge portion, despite having virtually the same pattern graph (as seen in the previous page). This could be attributed to the slightly larger standard deviation for the discharge portion, giving more leeway when finding outliers.

DC Pulse Internal Resistance (Discharge) Outliers
Mean: 0.04071 Ohms
Standard deviation: 0.0173 Ohms
Number of outliers: 9 (this is biggest head-scratcher, but perhaps the abnormally large standard deviation gives leeway for outliers)

Note that since the weight data had such a large variance, it had almost 900 outliers, hence the table is excluded for this page. Weight outliers were assigned a score of 1 (as before), meaning if the cell is an outlier for weight + any other category, it will be recommended for removal.
Master List of Cells to be Removed
The following list contains all cells that fulfill one of these criteria:
An outlier with a score of > 1 (not equal).
A cell with invalid types of all data (marked as “Invalid data” in table).
A cell with invalid weight data (marked as “Invalid weight data” in table).
In total, 362 cells are being recommended for removal.
