AI Customer ServiceTherefore, 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.
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.
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
Out of 172 brand-new lithium-ion battery cells, pairs are built to practically represent the ΔR and ΔC scenarios. If a charging pulse is applied to the ΔR scenario, currents initially divide according to the current divider but equalize in constant current phases. The current divider has no effect on ΔC pairs but, as a rule of thumb 1. Introduction
Gogoana et al. focused on the matching of the internal resistances of parallel-connected lithium-ion battery cells. The measurements were done with two LiFePO 4 battery cells connected in parallel . The used set-up is described without any explanation of the wiring, the additional impedances, or the used sensors.
Based on the results, they show that for parallel-connected battery cells with nonuniform parameters the single capacities sum up . Most recently, Shi et al. published their study on currents within parallel-connected 60 Ah LiFePO 4 battery cells and proposed a battery management system (BMS) to control the current distribution.
