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.
Are series and parallel connection of lithium batteries safe?
The series and parallel connection of lithium batteries is a key technology to increase voltage and capacity, but it also contains safety risks. This article will analyze in detail the principles, methods and precautions of series and parallel connection of lithium batteries to help you avoid potential risks and build a battery system correctly.
What is the difference between series and parallel batteries?
Both of these designs have strengths and weaknesses. Hence both have places where they are optimal. Parallel and then series will be the lowest cost, but least flexible. Series and then parallel gives flexibility and redundancy and hence is often found in large battery packs.
What is a series-parallel battery?
The series-parallel configuration can give the desired voltage and capacity in the smallest possible size. You can see two 3.6 V 3400mAh cells connected in parallel in the image below, which doubles the current capacity from mAh to mAh. Because these parallel packs are connected in series, the voltage also doubles from 3.6 V to 7.2 V.
How to charge parallel lithium battery packs?
Specific principles must be followed when charging parallel lithium battery packs: Use a matching charger: The voltage must be suitable for the nominal voltage of the individual batteries. The current setting is reasonable: usually 0.2-0.5C of the total capacity after parallel connection.
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.
