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:
In the battery pack, to safely and effectively manage hundreds of single battery cells, the cells are not randomly placed in the power battery shell but orderly according to modules and packages. The smallest unit is the battery cell. A group of cells can form a module. Several modules can be combined into a package.
A ‘single’ or ‘serial’ string has identical battery blocks wired in series. A typical string would have 32 12V 76AH batteries providing a d.c. bus voltage of 384V and a 76Ah capacity. Although normally the most cost effective, this solution has no redundancy as one battery failure will disable the whole string.
Battery cells, modules, and packs are different stages in battery applications. In the battery pack, to safely and effectively manage hundreds of single battery cells, the cells are not randomly placed in the power battery shell but orderly according to modules and packages. The smallest unit is the battery cell. A group of cells can form a module.
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.
UPS battery subsystems are typically configured as single strings for simplicity and cost reduction, yet create a potential single point of failure during a mains interruption. Multiple, parallel battery strings can solve this but are more expensive.
