Document ID: clinic-evse-4port-au-r10 · Audience: AU B2B green-tech procurement · Evidence-date: 2026-09-22 · Published: 2026-01-15 · Equipment: Schneider Electric EVlink Pro AC / AC Metal 22 kW per port, 4-port site · Horizon: 8 years · Limitation: this is an EV-vs-ICE fleet comparison, not a charger-revenue TCO.
Over an 8-year horizon at a 4% real discount rate, the modelled 4-port clinic EVSE deployment based on the Schneider Electric EVlink Pro AC / AC Metal 22 kW family is NPV-positive: NPV = 696,748.35 AUD, simple payback 0.1584 years (~58 days), discounted payback 0.1647 years (~60 days), IRR 6.31 (the IRR is a multiple, e.g. 631% — the underlying cashflow is dominated by fleet running-cost avoidance rather than charger capex). TCO per km is 0.1037 AUD/km for the EV versus 0.3032 AUD/km for the comparable ICE vehicle — a saving of 0.1995 AUD/km and 1,021,312.00 AUD over the 8-year horizon. Verdict: Procure (subject to AU site quote and final SKU selection between EVB3S22N4A socket variant and EVB3S22NCB cable variant).

Interpretation: Year 0 capex is 16,800 AUD (4-port Schneider EVlink Pro AC hardware + install bundle per the input envelope; EVB3S22N4A or EVB3S22NCB per port). Annual opex is ~1,200 AUD (back-office + maintenance), escalated at 2% p.a. to reach 1,378 AUD in Year 8. Annual benefit is 107,264 AUD per year (fleet running-cost avoidance vs. ICE over the modelled 160,000 km/yr fleet usage). Energy column is zero because the modelled benefit is computed in fleet-running-cost terms, not kWh sold.
Inputs the draft did not state are listed as model assumptions, not as sourced facts. All cost/benefit/horizon/discount figures in the COMPUTED TABLES above are computed and must not be re-derived in prose.

Reconciliation note (R11): the COMPUTED TABLES give TCO/km — EV = 0.1037 AUD/km and TCO/km — ICE = 0.3032 AUD/km, with savings per km = 0.1995 AUD/km. Earlier draft prose showing 0.1331 / 0.3410 / 0.2079 has been removed because it did not reconcile to the COMPUTED TABLES' cost / benefit / km drivers. Year-0 capex of 16,800 AUD and Year-1 opex of 1,200 AUD in the COMPUTED TABLES correspond to a 4-port bundle of ~4,200 AUD/port (capex+install) and ~300 AUD/port/yr (back-office+maintenance) on the Schneider EVlink Pro AC family.

Equipment named (R12 fix): Schneider Electric EVlink Pro AC / AC Metal 22 kW — EVB3S22N4A (T2S socket-outlet variant, 32 A 3P+N) and EVB3S22NCB (T2 attached-cable variant, 32 A 3P+N). Both variants carry RCD-DD 6 mA + RCD type A-Si 30 mA, IEC 61851-1 ed.3 conformance and OCPP 1.6 JSON, IK10/IP55 enclosure rating per the OEM product pages.
OEM manual title / revision (RFQ-pending): "EVlink Pro AC / AC Metal — Installation and User Manual"; document reference number and revision (e.g. REVxx / YYYY-MM) to be recorded after the AU site quote is issued. Until that revision is recorded on this page, all standards below apply generically to the EVlink Pro AC 22 kW class as confirmed by the cited product page.
Final conformance rests with the installer of record and the AHJ (Authority Having Jurisdiction). Tradvolt does not certify finished installations.

AU importer lookup instructions:
For reference, parallel lookups are available at USITC HTS, EU TARIC, UK Global Tariff, Japan Customs, and the WCO HS Nomenclature 2022 edition.
Disclaimer: Tradvolt does not assert any duty rate as fact. Customs classifications and rates change; always verify against the Australian Border Force Working Tariff and applicable FTAs (e.g. AANZFTA, ChAFTA, JAEPA) at the time of import. GST of 10% applies on the dutiable value for commercial imports. Sea-freight wood packaging must comply with IPPC ISPM 15; any in-shipment lithium batteries are subject to IATA DGR, ICAO Dangerous Goods and the UN Manual of Tests and Criteria (UN 38.3).

Request RFQ — 4-Port Clinic EVSE (AU)
Use the RFQ form to request a SKU-specific AU quote for either the Schneider EVB3S22N4A socket variant or the EVB3S22NCB attached-cable variant. Once the AU site quote is issued and the OEM manual title/revision is confirmed, that revision will be recorded in §5 and the COMPUTED TABLES re-checked against any newly confirmed inputs.
