With the popularity of electronic products, the application of LiPoly Batteries has become more and more widespread, and the safety performance and service life of LiPoly Batteries have attracted more and more attention.

The management system (BMS) of LiPoly Batteries plays an irreplaceable role in enhancing the safety of LiPoly Batteries and prolonging their service life. The history of the development of LiPoly Battery BMS can be traced back to the early 1990s. At that time, the research on BMS was limited to a few people in the United States and Japan. In the early days, people’s understanding of BMS was mainly reflected in the protection of LiPoly Batteries.

To prevent the overcharge and over-discharge of LiPoly Batteries, BMS was designed to cut off the charging and discharging current when the battery voltage exceeded the preset upper limit or fell below the preset lower limit. In addition, BMS can also play a role in balance. When the voltage of a single battery is significantly higher or lower than other LiPoly Batteries in the same pack, BMS can adjust the charging and discharging currents of these LiPoly Batteries to equalize the battery voltages.

With the continuous development of science and technology, people’s understanding of BMS is gradually improving, and the functions of BMS are also constantly expanding. In addition to the protection and balance functions mentioned above, BMS can also be used to monitor the working condition of LiPoly Batteries, display the working condition of LiPoly Batteries in real-time, and analyze and judge the working condition of LiPoly Batteries. Based on the analysis and judgment of the working condition of LiPoly Batteries, take corresponding measures to prevent or solve problems, to further improve the safety performance and service life of LiPoly Batteries. The working principle of BMS is very simple. BMS is composed of a control board, a display screen, a set of sensors, and a set of battery packs.

The working principle of BMS is to detect the working condition of LiPoly Batteries in real-time through sensors, analyze and judge the working condition of LiPoly Batteries through microcontrollers, and take corresponding measures to prevent or solve problems through relay switches. At present, many companies are producing BMS products globally, and the functions of BMS products are also constantly improving. With the continuous improvement of people’s understanding of LiPoly Batteries and the continuous development of battery technology, the functions of BMS will be further expanded, and BMS will play an increasingly important role in enhancing the safety performance and service life of LiPoly Batteries.
