Battery Management System (BMS) Performance Test with 1- Cell, 2-Cell and 3-Cell Battery Arrays

Batteries are one of the storage media for electrical energy whose development is quite significant. A battery if there is no monitoring on its use will cause damage to the battery itself such as a battery that heats up quickly, leaks and bubbles. Currently, there are quite a lot of battery management systems available as battery monitoring and controlling modules to avoid overcharge, overdischarge and overcurrent that have the potential to damage battery quality. Tests on the battery management system (BMS) as a monitoring and controlling module are carried out in this article. Tests were carried out on BMS 1S, 2S, and 3S series with Li-Ion 18650 2200mAh 3.7 V Battery type. The results of the BMS controling test show that the overcharging and overdischarging protection functions can work well. While the results of monitoring the cut off value of overcharging protection of each BMS are 3.7 V, 7.2 V, and 11.1 V. The cut off value of overdischarging protection of each BMS is 3.23 V, 6.1 V, and 9.23 V.
