The statistics of the Vc-end (3 lines at the top), Vd-end (3 lines at the bottom) and Vd-30min (3 lines in the middle) of 20 cell-series modules operated at various C-rates with cells produced by different battery makers. (a) 20 cells from Panasonic, NCR18650BE, 3.0Ah; (b) 20 cells from LG Chem, 18650 B4, 2.6Ah; (c) 20 cells from Lishen, LR1865SK, 2.6Ah. The tests were carried out at 0.1 (black), 0.5 (red) and 1.0 (blue) C-rate, respectively. The tested 20 cells were the most uniform ones screened by CiS from stochastic 80 cells, respectively.
