Battery Sizing (Substation DC)

Screen and size a DC station battery bank using a load profile and standard factors.
Method: Sum amp‑hour demand over the duty cycle and apply design, aging, and temperature factors.
Standards: IEEE Std 485 (Lead‑acid sizing), IEEE 1115 (Ni‑Cd), IEEE 1184 (Selection), NEC Article 480 (Storage batteries). Results are for preliminary sizing; confirm with manufacturer curves.

Enter any number of steps. Lines can include comments after a #.

Represents discharge rate/voltage & end-of-discharge effects. Use 0.8–0.9 for screening.

e.g., 4 hours (240 min) for station service without charger.
