Technical FAQs 4

What happens if a lithium-ion battery is connected parallel?

Uneven electrical current distribution in a parallel-connected lithium-ion battery pack can result in different degradation rates and overcurrent issues in the cells. Understanding the electrical current dynamics can enhance configuration design and battery management of parallel connections.

Is parallel connection safe in battery energy storage systems?

36. Jocher, P. ∙ Steinhardt, M. ∙ Ludwig, S. Parallel connection of cells is a fundamental configuration within large-scale battery energy storage systems. Here, Li et al. demonstrate systematic proof for the intrinsic safety of parallel configurations, providing theoretical support for the development of battery energy storage systems.

Why do lithium ion batteries need to be connected in series?

To meet the power and energy requirements of the specific applications, lithium-ion battery cells often need to be connected in series to boost voltage and in parallel to add capacity . However, as cell performance varies from one to another [2, 3], imbalances occur in both series and parallel connections.

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.
