6 FAQs about [14 lithium battery strings converted to 13 strings]

Can a lithium ion battery pack have multiple strings?

Whenever possible, using a single string of lithium cells is usually the preferred configuration for a lithium ion battery pack as it is the lowest cost and simplest. However, sometimes it may be necessary to use multiple strings of cells. Here are a few reasons that parallel strings may be necessary:

How many strings should a lithium battery have?

Therefore, the lithium battery must also be about 58v, so it must be 14 strings to 58.8v, 14 times 4.2, and the iron-lithium full charge is about 3.4v, it must be four strings of 12v, 48v must be 16 strings, and so on, 60v There must be 20 strings in parallel with the same model and the same capacity.

Why are parallel lithium strings important?

Since lithium cells must be managed on a cell level, parallel lithium strings dramatically increase the complexity and cost of the battery management and introduce many additional points of failure and failure modes not found with a single string.

What is a battery string?

A battery string with a large number of cells connected in series and in parallel is necessary for many applications that require high power and high voltage, such as electric vehicles (EVs), hybrid electric vehicles (HEVs), and energy storage systems (ESSs) [ 1 ].

What is a ternary lithium battery?

The ternary lithium battery standard specifies a voltage of 3.7v, full of 4.2v, three strings are 12v, 48v requires four three strings, but the electric vehicle lead-acid battery is fully charged with 58v.

How many volts in a ternary lithium battery?

Two 10ah batteries in parallel are 20ah, 48v ternary lithium must be 14+14 10ah batteries, and finally 14 parallel connected in series to form a 48v20ah lithium battery. Calculation method two: In fact, it is very simple. For example, 48 volts usually refers to voltage.
