Parallel-Connected Battery Current Imbalance Dynamics

Lithium-ion battery cell formation: status and future directions towards a knowledge-based process design

“…However, some challenges to the general applicability of using DVA to quantify Li stripping have been raised in the recent work of O'Kane et al 396 In conclusion, DVA is another technique complementary to CLI based techniques. It provides additional information and can be applied as a manufacturing process control measure, 397 but the interpretation of measurement results is more demanding.…”

Detecting faulty lithium-ion cells in large-scale parallel battery packs using current distributions

“…39 The extent to which this computational solution has been used indicates the applicability of the analytic solution of Equation 3 to understand these nonlinear parallel pack dynamics. Moreover, the proposed approach overcomes some of the restrictive assumptions of existing analytical solutions, such as the OCV being affine 40,41 and the cell-level model simply being a voltage source and a series resistor. 42,43 Instead, with Equation 3, the voltage is allowed to be of the form of Equation 1, as in the sum of a linear series resistance term and a nonlinear function of the states.…”
