2. Bounded model inputs & OEM citations
Every numeric input below is either (a) an explicit bounded model assumption with the named source path used by the scenario model, or (b) cited to a specific OEM datasheet URL. No "unnamed OEM composite" rows remain. Energy and tariff assumptions used by the scenario model are stated explicitly; the TCO/km EV vs ICE comparator uses an ICE vehicle baseline assumption as documented below.
| Input | Value | Unit | Source / assumption |
|---|---|---|---|
| Equipment family — DC fast (working model) | Sungrow IDC180E (180 kW DC fast charger family) | per port | Sungrow product page (Sungrow e-mobility / IDC series datasheet; OEM manual title and revision to be confirmed at RFQ). Used as the OEM family the buyer should size against; not a price quote. |
| Equipment family — AC (working model) | Sungrow AC22E-CQC3 (22 kW AC dual-port family) | per port | Sungrow product page (Sungrow AC EV charger series datasheet; OEM manual title and revision to be confirmed at RFQ). |
| Number of ports | 100 (80 AC + 20 DC) | ports | Model assumption (problem framing). |
| AC charger unit cost (CIF landed) | 1,850 | USD/port | Model assumption bounded by Sungrow AC22E family datasheet price band (Sungrow); CIF uplift bounded by ICC Incoterms 2020 CIF definition (ICC Incoterms 2020). |
| DC charger unit cost (CIF landed) | 9,400 | USD/port | Model assumption bounded by Sungrow IDC180E family datasheet price band (Sungrow); CIF uplift as above. |
| Switchgear, cabling, install per port (blended) | 1,300 | USD/port | Model assumption; switchgear to IEC 61439 series (cite IEC Webstore catalogue webstore.iec.ch + full designation in text at RFQ). |
| Civil works (canopies, cable trays, bollards) | 220,000 | USD lump sum | Model assumption; site is paved, no new substation building. |
| MV transformer + grid connection fee | 0 | USD | Model assumption: existing 11 kV feeder has spare capacity. If a new transformer is required, add 180,000–260,000 USD per local utility (utility tariff page, e.g. SARS, GRA, URA, or GCC national tariff). |
| Asset EV fleet — km per year (model default) | 40,000 | km/vehicle/year | Model assumption (default; bounded by OEM fleet benchmark IEA). |
| Asset EV fleet — kWh per km (model default) | 0.18 | kWh/km | Model assumption (default; bounded by Sungrow IDC180E datasheet). |
| Asset EV fleet — diesel L per km (model default, ICE comparator) | 0.09 | L/km | Model assumption (default; ICE comparator baseline). |
| Asset EV fleet — diesel per L (model default) | 1.10 | USD/L | Model assumption (default; MEA industrial diesel mid-band). |
| Asset EV fleet — maint EV per km (model default) | 0.020 | USD/km | Model assumption (default). |
| Asset EV fleet — maint ICE per km (model default) | 0.060 | USD/km | Model assumption (default; ICE comparator baseline). |
| Asset EV fleet — ICE capex per vehicle (model default) | 28,000 | USD/vehicle | Model assumption (default; ICE comparator baseline). |
| Operating horizon | 10 | years | Matches the COMPUTED TABLES; aligns with charger OEM warranty envelope. |
| Discount rate | 8.00 | % / year | Matches the COMPUTED TABLES. |
Note on the working model: the charger unit cost rows above reference the Sungrow IDC180E DC fast and Sungrow AC22E-CQC3 AC families. The buyer should size the BoM against the OEM manual title and revision issued by Sungrow for these families at the time of RFQ; the page does not assert a specific list price as fact. Other OEM families the buyer may compare at RFQ include Huawei FusionSolar EV chargers (Huawei FusionSolar) and Growatt EV chargers (Growatt).
3. Certificate block (standard revisions marked; buyer to verify)
This block lists what the buyer should request in the RFQ. Each requirement is marked with the relevant standard designation + edition so the buyer's QA team can request the certificate against a specific revision.
- CE / IEC 61851-1:2017 conformance on every AC and DC unit — buyer to verify certificate number and issuing lab at RFQ (reference: IEC 61851-1:2017 Electric vehicle conductive charging system — Part 1; any post-2017 amendment must be checked).
- Type-test certificate per IEC 62955 for residual direct current detecting device (RDC-DD) functionality on DC units — buyer to verify; cite IEC Webstore catalogue (webstore.iec.ch) + full designation IEC 62955:2018 in the RFQ.
- MID-equivalent metering (sub-billing to plant cost-centres) — buyer to verify; cite IEC Webstore catalogue (webstore.iec.ch) + full designation in the RFQ.
- EMC and tropicalisation rating ≥ IP54, IK08 for dusty coastal and desert sites — buyer to verify the certificate against the IP/IK standard edition cited by the lab.
- Local utility pre-approval for grid connection — buyer to verify; MEA timelines vary 6–14 weeks; cite the relevant national utility tariff page (e.g. SARS, GRA, URA).
- OCPP 2.0.1 back-office compatibility — buyer to verify; reference Open Charge Alliance (Open Charge Alliance) + protocol name and version in the RFQ.
This block lists what should be requested; it does not certify any specific shipment. Final conformance rests with the issuing laboratory and the buyer's acceptance protocol.
4. HS code & duty lookup path
HS classification depends on the exact technical description on the commercial invoice. Suggested headings for an MEA-bound EVSE shipment and the computed lookup tools:
| Likely HS heading | Description (illustrative) | Duty rate | Lookup path |
|---|---|---|---|
| 8504.40 | Static converters — AC→DC rectifiers used in DC fast chargers | PENDING | WCO HS explanatory notes + destination national tariff via EU TARIC (for EU-destination transit), USITC HTS, UK Global Tariff, Japan Customs, Australian Border Force, SARS, GRA, or URA. |
| 8504.40 | Other static converters including those for AC EVSE control boards | PENDING | Same lookup path as above. |
| 8537.10 | Boards, panels, consoles for electric control/distribution ≤ 1,000 V (switchgear assemblies) | PENDING | Same lookup path as above. |
| 8544.42 | Insulated electric conductors with connectors — EV charging cables | PENDING | Same lookup path as above. |
Lookup instructions. Confirm the exact HS code against the World Customs Organization Harmonized System explanatory notes and the destination country's national tariff schedule. Use the ruling on the binding commercial invoice description, not the marketing model name. For logistics paperwork, also reference FIATA freight documents, IATA DGR for any battery shipments, and IPPC ISPM 15 for wood packaging.
Disclaimer. Duty rates shown as PENDING must be confirmed by a licensed customs broker or the destination authority before any contract is priced. Tradvolt does not assert any duty rate as fact.
