A battery management system (BMS) is described along with important features for protecting and optimizing the performance of large 18650 lithium power battery packs. Of particular interest is the selection of many cells, that is, according to the system needs to choose healthy cells into the system to run. In order to shorten the cycle of research, the paper proposed a BMS based on virtual instrument (VI) data acquisition system. It can monitor parameters such as monomer voltage, total voltage, current, temperature, estimating state of charge (SOC) etc, and it also can control switch when a parameter exceeds the allowed range, the corresponding monomer cell will be automatically cut off the switch and alarm. Experimental results are included for a pack of seven 2.2 Ah (amp-hour) 18650 lithium power cells. It can monitor the status of the lithium-ion battery pack according to the security metrics of 18650 power lithium cells. It can control other types of power batteries by means of modified index.
