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.

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

What is a 1S4P battery pack?

To verify the lithium battery software model and the hot-swap experiment, a 1S4P battery pack was designed. Current sensors and relays were allocated for each cell unit to implement the hot-swap function for the parallel connection of batteries in series units of the ESS system.

Is state of charge a condition for parallel connection of batteries?

Two previous studies [ 10, 11] used the state of charge (SOC) as a condition for the parallel connection of batteries. Since the state of charge of the battery is an estimated value, there may be an error compared to the actual state of charge.
