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 volts are in a battery pack?

If each cell is 10 amp hours and 3.3 volts, the battery pack above would be 10 amp hours and 26.4 volts (3.3 volts x 8 cells). For this setup, a BMS capable of monitoring 8 cells in series is necessary. Lithium cells can almost always be paralleled directly together to essentially create a larger cell.

What happens if a battery is low voltage?

The good cell's voltage will drop as it discharges. The BMS should identify low voltage in this cell pair. During balancing, this cell pair will take longer to raise up to the correct voltage. If the cell pair's low voltage is severe then the BMS would switch off the entire battery.

Should a battery pack be paralleled?

Paralleling strings together greatly increases the complexity of managing the battery pack and should be avoided unless there is a specific reason to use this configuration. In this setup, each string must essentially be treated as its own battery pack for a variety of reasons. In a below example, 2 strings of 8 cells each are placed in parallel.

How does a battery pack work?

Since the charging is handled and controlled by the charger on each string, each battery pack is only responsible for providing discharge current to the common DC bus. This completely eliminates the possibility of eddy currents and of damage to the charge equipment since each charger is controlled individually by each string's BMS.

How does a bad cell affect a pack's performance?
