Modular Lithium Batteries

| LiFePO4

The AEC Lithium System integrates power distribution, and hot‐swappable 50 Ah LiFePO4 battery modules into a compact cabinet, delivering high-density, reliable backup for critical applications such as data centers, healthcare, telecom, and industrial facilities. AEC unique modular and parallel battery architecture supports up to 20 x 50 Ah packs per cabinet and enables online capacity expansion with minute‐level maintenance, minimizing both CAPEX and OPEX. The adopted three-layer BMS architecture (PBMU/SBMU/ MBMU) ensures the reliability of lithium-ion battery system from cell, module and system layers.
