Battery configurations (series and parallel) and their protections

Sometimes, battery packs are used in both configurations together to get the desired voltage and high capacity. This configuration is found in the laptop battery, which has four Li-ion cells of 3.6 V connected in series to get 14.4 V. Each cell has one another cell connected in parallel to obtain the double capacity of 6800mAh. Figure 1.

6 FAQs about [Lithium battery pack parallel protection]

Can lithium batteries be connected in parallel?

Lithium batteries can indeed be connected in parallel, and this method is commonly used to achieve higher capacity and extend the runtime of a battery system. By connecting two or more lithium batteries with the same voltage in parallel, the resulting battery pack retains the same nominal voltage but boasts a higher Ah capacity.

What are the advantages of parallel lithium batteries?

Parallel lithium batteries have many advantages, including increased capacity, enhanced power output, and improved overall performance. When multiple batteries are connected in parallel, their individual ampere-hour (Ah) capacities add up, resulting in a higher total capacity.

What happens if a lithium battery cell is shorted in parallel?

) The failure of the lithium battery cell automatically exits, except for the reduced capacity, it does not affect the use after parallel; when a lithium battery cell is shorted in parallel, the current in the parallel circuit is very large, which is usually avoided by fuse protection technology.

How do you design a lithium battery pack?

When designing a lithium battery pack, engineers have two primary options: connecting individual cells directly in parallel or connecting strings of cells in parallel. Each approach has its advantages and disadvantages, and the choice depends on the specific application needs and design goals.
