loading . . . AC-native battery systems AC-native battery systems reframe batteries from passive DC energy sources into active energy-processing platforms. By relocating controllable power-conversion capability inside the battery module or pack, they hold promise in enabling internal AC waveform synthesis, topology-aware current routing, enhanced state observability, controllable stress redistribution, and active fault isolation. The broader significance lies in a new architectural design space where batteries, power electronics, embedded sensing, and real-time control converge, while practical adoption remains shaped by cost, reliability, qualification, and system-level trade-offs. http://dlvr.it/TSsHW0
