Current distribution inside the battery cabinet

How is current distributed in a cell?

Current distribution depends on the individual performance of every cell and the characteristics of the electrical connections between these [ 3]. Uneven current loads result in diverging states of charge (SoC) during operation and inhomogeneous ageing.

What are the discharge characteristics of multicell lithium-ion batteries?

Discharge characteristics of multicell lithium-ion battery with nonuniform cells Unbalanced discharging and aging due to temperature differences among the cells in a lithium-ion battery pack with parallel combination Effects of imbalanced currents on large-format LiFePO 4/graphite batteries systems connected in parallel

What is the difference between a current divider and a battery divider?

The rule of thumb says that the current at the beginning of a current step can be calculated according to the current divider equation in an impedance difference scenario, whereas currents divide proportionate to the battery cell capacities (in a long-term behaviour) in a capacity difference scenario. Table 1.

Is there a nondestructive assessment of current distributions within rechargeable Li-ion cells?

In summary, we have demonstrated here an MRI-based technique for the nondestructive assessment of current distributions within rechargeable Li-ion cells. The technique, referred to as an “inside-out” MRI approach (ioMRI), pointed to an asymmetry in the current distributions between charging and discharging, which evolved as a function of SOC.
