6 FAQs about [Large single-cell lithium battery packs connected in parallel]

How to connect a lithium battery pack?

To connect a lithium battery pack, the typical methods are connecting first in parallel and then in series, first in series and then in parallel, or mixing the parallel and series connections together. For a lithium battery pack used in pure electric buses, the connection is usually made first in parallel and then in series.

How to choose a lithium battery for a parallel connection?

When connecting lithium batteries in parallel, it is necessary to select batteries with the same voltage, internal impedance, and capacity for matching. Due to the consistency issue of lithium batteries, this is essential for the same system (such as ternary or lithium iron) in a parallel connection.

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.

Which battery pack should be connected first?

When connecting lithium battery packs in parallel and series, the packs for pure electric buses are usually connected first in parallel.

Should a battery be connected in parallel?

When connecting batteries in parallel, it's crucial that the batteries have consistent parameters, such as capacity and internal resistance, to maintain optimal performance. If the batteries do not have consistent parameters, the performance of the battery pack can be significantly worse than that of a single cell.

What is a lithium battery pack?

A lithium battery pack is a collection of lithium cells assembled together, referred to as 'PACK'. The pack can consist of cells connected in series or parallel. It is called a lithium battery pack. The pack usually includes a plastic case, PCM, cell, output electrode, bonding sheet, and other insulating and double-coating tapes.
