Influence of the connection topology on the performance of lithium-ion battery pack under cell-to-cell parameters variations …
Subsequently, the direct current resistance (DCR) is the sum of the pure ohmic resistance and the polarization resistance, which is typically used to describe the power capability of the battery. In this paper, DCR of ith cell is tested and calculated (ΔV /ΔI) by a C/3 current pulse for the duration of 100 s, as shown in Fig. 1 (a) for a measurement …
