Objective:
...
Pick up a cell from the packaging
Number it with Sharpie
Place in the Gamry cell holder with a Keysight 34410a
Measure the OCV of the cell
Collect the IR via the Keysight 34410a
Add data to the designated row: MSXV_celltracking
Place the cell in a box labelled ‘Tested’
Production (Capacity) [DRAFT]
Place cells into [parallel cell charger(s)]
Charge cells at 1.45A (well below the standard charge spec [5])
Observe the thermal performance of batteries via thermistors/heat gun [optional]
Once fully charged, allow the cells to rest for 10 mins (recommended per spec sheet [5])
Commence discharge on [parallel cell charger(s)] at 1.70A
Once fully discharged, record values in the following MSXV_celltracking
Allow the cells to rest for 20 mins
Charge cells at 1A (well below the standard charge spec [5])
Observe the thermal performance of batteries via thermistors/heat gun
Once fully charged, allow the cells to rest for 4+ hours for the temperature to normalize temperature
Place all batteries in a box until module/pack assembley - when placing them in your module, check ocv and make sure it hasn’t dropped to much (self-discharge check), if discrepancies: record in MSXV_celltracking
