FAQs 6
Do parallel-connected battery cells have a current distribution?
Wu et al. investigated parallel-connected battery cells and their current distribution by numerical simulation. They interpolated the terminal voltages of battery cells from a data field of voltage measurements at different states of charge (SoC) and discharge currents .
How many lithium-ion battery cells are in parallel?
Gong et al. investigated the current distribution for up to four 32 Ah lithium-ion battery cells in parallel. The current distribution was measured with Hall effect current transducers but the wiring and the electrical connection of the battery cells are not described .
What is the current distribution for parallel battery cells with different impedances?
Current distribution for parallel battery cells with differing impedances In this section, the current distribution for the ΔR pair is measured and simulated for a current pulse. The amperage of the charging pulse is itot = 3 A and it lasts for 1000 s.
Can a current divider determine the current distribution within parallel-connected battery cells?
Therefore, it is proven that the current divider is suitable to determine the current distribution within parallel-connected battery cells at the beginning of current changes. The initially unequal current distribution causes an imbalance in charge throughput qdiff and, linked to that, a difference in the OCVs u0,diff develops.
How are current distributions measured in battery cells?
The currents of the battery cells were measured via shunts of 0.25 mΩ and via Hall effect current transducers . Current distributions were investigated for different state of health (SoH) but only for complete charge and discharge cycles .
How can a test bench reduce currents of parallel-connected battery cells?
Own preliminary works revealed that a lot of effort has to be put into the design of the test bench to minimize the influence on currents of parallel-connected battery cells . Additional impedances are caused by connection wires, current sensors, and contact resistances between the test bench and the battery cell terminals.
