Technical FAQs 4

Do parallel-connected lithium-ion cells affect battery cycle life?

Internal resistance matching for parallel-connected lithium-ion cells and impacts on battery pack cycle life 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

Are parallel-connected lithium-ion batteries safe?

Abstract: In electric vehicle applications, lithium-ion batteries are usually used in parallel connections to meet the power and energy requirements. However, the impedance and capacity inconsistencies among the parallel-connected batteries (P-LiBs) can lead to uneven current distribution, resulting in accelerated aging andsafety issues.

Why are batteries connected in parallel?

Cells are often connected in parallel to achieve the required energy capacity of large-scale battery systems. However, the current on each branch could exhibit oscillation, thus causing concerns about current runaway or even system divergence.

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.
