Use-case reference: indoor parking-garage-43kw deployment of a 43 kW AC EVSE — OEM family Starcharge EVDC43-EU (Star Charge / Star Energy Technology Co., Ltd.), SKU evse-ac-43kw — sourced from China and imported into Nigeria. The figures below are produced by the computed Tradvolt TCO model under the bounded scenario in §10; they are not an offer.
Inputs are framed around a single Starcharge EVDC43-EU parking-garage unit. Marine freight and insurance are illustrative per-unit allocations for a shared container; confirm with the freight forwarder. Each cost line carries the allow-listed source-of-evidence document. Duty (§1.8) and VAT (§1.9) remain PENDING — lookup.

OpEx is uplifted at 2.00% p.a. from the 447.00 USD Year-1 figure (§2.7). Benefit (460.00 USD/yr) is held flat over the horizon in the COMPUTED TABLES; the computed tables are the sole source of the financial figures on this page. PV of costs is computed as Cost_0 + Σ_{t=1..25} Cost_t / (1.08)^t and PV of benefits as Σ_{t=1..25} Benefit_t / (1.08)^t; NPV = PV of benefits − PV of costs.
Certificate numbers and issuing bodies must be taken from the OEM datasheet for the exact Starcharge EVDC43-EU variant supplied (SKU evse-ac-43kw). This page does not assert any certificate number that is not on file.

Customs treatment for an AC EVSE imported into Nigeria must be confirmed against the Nigeria Customs Service (NCS) HS national line at the time of import. Static converters and EVSE typically reference Chapter 85 (commonly 8504.40 / 8504.90 class lines), but the exact national line, applicable duty program, and any VAT / levy treatment depend on the NCS tariff schedule and any active fiscal policy at assessment.
| Component | Rate | Source-of-truth portal (specific page) | Notes |
|---|---|---|---|
| Import duty | PENDING — lookup | Nigeria Customs Service portal (HS national-line lookup) | Confirm exact national line; do not assume. For cross-reference with non-Nigeria duty regimes see EU TARIC consultation, USITC Harmonized Tariff Schedule search, UK Global Tariff lookup. |
| VAT / levies | PENDING — lookup | Federal Inland Revenue Service | Computed on duty-inclusive value per NCS practice. |
| SONCAP / MANCAP | Confirm with appointed SON agent | SONCAP programme page (SON) + SON product certification (PC/SC) | Required for market access; not a duty line. |
No duty or VAT rate is hardcoded on this page. A live importer must verify the HS national line and the active duty program against the official NCS tariff at the time of import.

Allow-list applied: OEM datasheets (Starcharge), IEC standards bodies (IEC Webstore), official customs/tariff portals (Nigeria NCS, FIRS, NPA, SON, NSW), ICC rules, and Open Charge Alliance. No blogs, forums, AI summaries or aggregator pages were used. No EU/UK/US/JP/AU duty rate is asserted for this Nigeria-bound use-case; cross-reference lookups are listed only as additional computed portals, not as bound rates.
Under the bounded scenario in §10 (1 charger, parking-garage-43kw, Nigeria, 25-year horizon, 8.00% discount rate), the scenario model returns NPV = -5,084.90 USD, simple payback None, discounted payback None, TCO/km EV 0.1283 USD vs ICE 0.2290 USD. On the stated benefit stream the project does not recover CapEx; the EV-vs-ICE TCO advantage (0.10 USD/km) is real but does not by itself produce a positive project NPV at the per-asset benefit rate. Subject to confirmation of OEM proforma, freight quotation and NCS duty/VAT at import.
Static converters for EVSE commonly fall under Chapter 85 (commonly referenced as 8504.40 or 8504.90 class lines). The exact national line, duty program, and VAT treatment must be confirmed against the NCS HS national-line page at the time of import. See §5; rates are marked PENDING — lookup.
Verify the OEM datasheet for the specific certificate numbers issued by accredited bodies. Typical references for AC EVSE include IEC 61851-1:2017 and IEC 62196-2:2022; SONCAP/MANCAP apply for Nigeria market access via the SON programme (SONCAP programme page, SON product certification), filed through the National Single Window. This page does not assert specific certificate numbers without an OEM datasheet on file.
No. All CapEx, OpEx, payback and sensitivity numbers are produced by the computed Tradvolt TCO model from the bounded scenario in §10 — ILLUSTRATIVE — NOT A QUOTE. They depend on the OEM quotation, freight Incoterm, Nigerian port charges, grid tariff, parking operator fee split, and duty treatment confirmed by NCS at the time of import.
Common options are FOB, CIF and DAP (named Nigerian inland point), per ICC Incoterms 2020. The choice shifts responsibility for ocean freight, insurance, and last-mile logistics between seller and buyer; it does not change the underlying Nigerian customs duty and VAT liability, which are assessed by NCS on the customs value. Confirm terms in writing with the OEM quotation.
Beyond the unit, budget for upstream distribution upgrade (cable sizing, breaker rating, earthing per IEC 61851-1:2017), energy-meter / sub-billing hardware if revenue-grade metering is required, OCPP backend subscription (via Open Charge Alliance (OCPP)-conformant SaaS), signage and bay marking, civil works for cable trays in a parking-garage environment, and ongoing O&M including firmware updates and SLA-based field service.
Inputs the draft did not state are presented here as explicit bounded assumptions used by the computed Tradvolt TCO model. They are not sourced facts. Per the COMPUTED TABLES contract, no closed-form derivation, methodology section, or worked check appears on this page; the COMPUTED TABLES in §3 are the sole mathematics.

These inputs are bounded model assumptions, not sourced facts. Confirm before relying on §3 figures for a live procurement decision; rerun the model after each input change. Per the TCO-per-km reconciliation: TCO/km = (PV of costs over horizon) ÷ (annual_km_basis × horizon). The savings-per-km figure follows from TCO/km − ICE minus TCO/km − EV; savings-over-horizon = savings_per_km × annual_km_basis × horizon.
