Itake screenshoot of those curves, theNO.1-16 cells discharge curves, the whole battery pack discharging curves, for comparison.

Testing machine logged all 16 pcs of 3.2V100AH cells status,
and marked with different colors curves,
to identify the consistency of whole battery pack.

Testing procedures:

  1. charging the whole pack as standard 0.3C(30A) CC/CV.
  2. discharge Battery Pack as 1C (100A) continuous current,
    logged the NO.1-16 cells status, log the whole battery status.
  3. charging the whole pack as 0.5C(50A) with abnormal charging current test,
    abnormal charging current could be seem in curves.
  4. discharge Battery Pack as 2C (200A) continuous current,
    logged the NO.1-16 cells status, log the whole battery status.
  5. charging the whole pack as 0.5C(50A) with abnormal charging current test,
    abnormal charging current could be seem in curves.
  6. discharge Battery Pack as 3C (300A) continuous current,
    logged the NO.1-16 cells status, log the whole battery status.

3C continuous discharge curve (3.2V 100AH, in 22’C temperature)

2C continuous discharge curve (3.2V 100AH, in 22’C temperature)

1C continuous discharge curve (3.2V 100AH, in 22’C temperature)

When 3C (300A) continuous discharge, the whole pack curve could be seem as below.

When 1C (100A) continuous discharge, the whole pack curve could be seem as below.
