However, the experimental results of the 4-series 2-parallel battery pack in Section 3.2 have shown that the loop current exists during normal charging. The loop current during normal charging is due to the weak SOH inconsistency, impedance inconsistency of every single cell, and the SOCs that are not precisely the same.
