A Smart BMS
Samsung SDI has developed a prototype of a next-generation battery management system (BMS) that can accurately figure out the state of batteries and will be able to mass produce it after next year, a company official said on April 13.
A BMS is literally a device that manages batteries. It maintains optimal conditions for batteries, increasing energy efficiency and extending battery lives. Specifically, it monitors voltage, current, and temperature in real time to prevent excessive charging or discharging. The importance of a BMS has grown as fires broke out in electric vehicles and ESSs at home and abroad over the past two years.
"The new BMS can predict such details as how the anode and cathode will deteriorate and whether electrolytes have not swelled," said Lee Tae-kyung, an executive director of Samsung SDI, at the Next Generation Battery Seminar (NGBS) 2022 held at COEX in Gangnam-gu, Seoul. "We are focusing on making our BMS intelligent and smart."
Samsung SDI has developed an algorithm that analyzes a battery’s status using artificial intelligence (AI).
Samsung SDI says that the next-generation BMS boost battery lives by 15 percent, car mileage by 6 percent, and energy output by 10 percent. It also implements wireless operation and cybersecurity functions.
