Verdict (base case): NPV = USD 280,404.42 over a 7-year horizon at an 8.00 % discount rate. Simple payback 0.4318 year (≈5.18 months), discounted payback 0.4664 year (≈5.60 months). IRR 2.31 (decimal, i.e. 231 %/yr). TCO per km USD 0.0553 (EV) vs USD 0.3041 (ICE); savings per km USD 0.2489; savings over horizon USD 696,840.00. Equipment scope: Huawei SCharger-7KS-S0 (7 kW, OCPP 1.6J) and Huawei SCharger-22KT-S0 (22 kW three-phase, OCPP 1.6J) from the Huawei FusionSolar Smart Charger family; supporting standards IEC 61851-1:2017 (conductive charging) and IEC 62196-2:2022 ed.3 (Type 2 coupler). Location: MEA data-hall cluster. Evidence date: 2026-01-15. Limitation: per-km figures and horizon savings reflect the bounded fleet assumptions in §5, not OEM-quoted line items; OEM unit capex is an internal placeholder until RFQ.

Scope: a 10-port EVSE hub adjacent to a Middle East & Africa (MEA) data-hall cluster, serving two duty classes:
Baseline mix: 7 × 7 kW AC + 3 × 22 kW AC. Both AC units are named to real Huawei FusionSolar Smart Charger SKUs (SCharger-7KS-S0 and SCharger-22KT-S0) — datasheet revisions are confirmed at RFQ. Pure-DC and AC-only variants are flagged as alternatives in §3. Grid-connection upgrade is excluded from the headline TCO and noted separately.

Editorial note: The numeric envelope in §4 is the only mathematics on this page and is produced by the tradvolt.com scenario TCO model from the bounded assumptions in §5. No closed-form check, worked derivation, or financial figure outside §4 is offered on this page. HS classifications in §6 are pending host-authority confirmation. Equipment designations in §2 are real OEM SKUs (Huawei SCharger-7KS-S0 and SCharger-22KT-S0); datasheet revisions are confirmed at RFQ per the cited OEM product page.
