A Parallel BMS plays an important role in achieving safe and efficient parallel battery configurations. It continuously monitors the voltage, temperature and charging status of each battery, ensuring that the battery is balanced and protected during the charge and discharge cycle. A BMS for parallel cells performs several essential functions:

In the above example, two BMS units, each capable of managing 8 cells in series must be used in conjunction with at least one contactor per string that automatically disconnects the string in the event of a failure, over-charge, over-discharge, or other fault.

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:

A BMS for parallel cells performs several essential functions: Cell Balancing: The BMS for batteries in parallel ensures that all batteries in the parallel configuration have similar state-of-charge levels. It can balance the charge across individual cells or strings to prevent overcharging or over-discharging of any particular battery.

If each cell is 10 amp hours and 3.3v, the battery pack above would be 20 amp hours (10 amp hours x 2 cells) and 13.2 volts (3.3 volts x 4 pairs). Even though there are twice the number of cells in this configuration, for this setup, a BMS capable of monitoring only 4 cells is necessary.
