Batteries are the backbone of the energy transition, powering everything from electric vehicles to home solar storage. But while batteries are often seen as hardware, their true potential depends on the intelligence that manages them: the Battery Management System (BMS). Traditionally, BMS has been built on rigid, rule-based logic, ensuring cells stay within safe operating limits. However, as energy storage demands grow more complex, conventional approaches fall short. This is where AI-powered BMS (AI BMS) steps in, redefining how batteries are monitored, controlled, and optimized.
