EV Station Load Sizing

The electrical designer's sizing tool for commercial EV charging sites — chargers to transformer in one honest screen. Add charger groups (7.4, 11, 22 kW AC · 50, 150, 350 kW DC fast, or any custom rating), apply a diversity factor you control, pick the supply (230 V 1φ · 400 V 3φ · 480 V 3φ, adjustable power factor) and read the results instantly: connected load, expected demand in kW and kVA, feeder current with the ×1.25 continuous-load design value (NEC 625.41), and the next standard transformer size from the ANSI/IEEE C57.12.00 ladder at ≤ 80% loading. Planning a capped connection? Set the site power limit and see the equal-split power each charger gets under load management (ALM/EVEMS, NEC 625.42). PRO • Unlimited chargers and groups (free sizes up to 2 devices) • Site-cap load sharing with per-charger power • Transformer sizing: required kVA, standard unit, loading verdict • Save site assessments to history • Clean one-page PDF reports with the full assumptions list — ready for the project folder Built for the field: big controls, huge results, Outdoor Bright mode for direct sunlight. Everything stays on your phone — fully offline, no account, no tracking. Diversity is an assumption: results are planning estimates and require engineered project approval. ——— Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://hdappstudio.com/evstationload/privacy/
