Engineering Disciplines — BESS

Battery Energy Storage

FrameAI BESS automates the engineering documentation for battery energy storage systems — from initial feasibility sizing to NFPA 855 commissioning packages. Battery sizing per IEC 62933-2-1, grid interconnection per IEEE 1547-2018, thermal runaway analysis per UL 9540A, and cycle life degradation modelling using the Arrhenius equation. Handles both utility-scale utility BESS and commercial & industrial (C&I) behind-the-meter installations.

Worked Examples

"2 MWh BESS: LFP chemistry, 200 kWh strings, 10 strings per container. DC bus V = 1 500 V. Ampacity at C/2 = 667 A → 3 × 630 mm² Cu cable per string — PASS."
