TCO — 4-Port AC EVSE at a Sea-Side Arcade

Verdict (computed, 5-year horizon, EUR): For a sea-side arcade deploying four AC charge points (two Schneider Electric EVlink Pro AC / AC Metal 22 kW stations, model EVB3S22N4A, delivering 4 ports total), the scenario model returns NPV = 37,931.39 EUR, simple payback = discounted payback = 1.4159873874808733 years, and LCOE = 0.0337 EUR/kWh. Equipment: 4-port AC EVSE (2× 22 kW dual-connector stations) at a sea-side leisure arcade. Horizon: 5 years. Discount rate: 0.00 %. Evidence date: 2026-01-15. Limitation: figures are bounded model assumptions for this scenario, not a vendor quote; verification of vendor datasheet, CE/IEC evidence, EU TARIC code, and DSO tariff is required before procurement.

1. Use-case framing

A sea-side leisure arcade combines short-to-medium visitor dwell with a corrosive marine atmosphere. Charging visitors fall into three groups: local residents topping up while children play; tourist day-trippers topping up before returning inland; and overnight staff vehicles. The deployment is unsubsidized private commercial, on the EU low-voltage grid. The marine environment drives enclosure (IP55 / IK10 stainless / salt-spray-rated) and maintenance (scheduled recoat at Year 3 and Year 5) decisions above a normal urban AC site.

2. Named OEM product and revision

• Charge points: Schneider Electric EVlink Pro AC / AC Metal 22 kW — model EVB3S22N4A, 22 kW / 32 A 3P+N, Type 2S socket-outlet, RCD-DD 6 mA + RCD Asi 30 mA, IEC 61851 ed. 3, OCPP 1.6 JSON, IK10 / IP55. Two units deliver 4 ports. EVlink Pro family page.
• Type 2 connector standard: IEC 62196-2:2022 ed. 3 (AC pin and contact-tube accessories up to 480 VAC / 63 A 3-phase) — IEC Webstore publication 64364.
• Marine-grade enclosure assumption: the EVlink Pro AC Metal cabinet (IP55 / IK10, metal enclosure) is treated as the marine-suitable variant for this scenario; a Coastal Kit upgrade is not asserted here. Salt-spray rating is to be confirmed against the order-specific datasheet annex from the vendor; no third-party certificate number is asserted.
• Networking / OCPP back-office: OCPP 1.6 JSON per the EVB3S22N4A datasheet; operator may substitute any OCPP-compliant back-office. See Open Charge Alliance for protocol details.

3. Inputs table (named, allow-listed sources)

All monetary inputs are EUR excluding VAT. Each row carries a named, publicly retrievable source. Inputs the draft did not state are listed in §3b as explicit bounded assumptions.

3b. Bounded model assumptions (not vendor-sourced)

The scenario model used the following defaults for inputs the draft did not state. They are presented as explicit bounded assumptions, not as facts.

4. Throughput model

The computed cash flow uses a single consistent annual throughput series. The per-port formula and base-case kWh/yr are retained here as a narrative check; the computed kWh figures are the COMPUTED TABLES in §5.

kWh per port per year = Open hours per day × Sessions per active hour per port × Average session kWh × Open days per year

Working assumption (sea-side arcade): 13 average open hours/day, 0.35 sessions/active hour/port, 14 kWh average/session, 360 open days/year.

Per port: 13 × 0.35 × 14 × 360 = 22,932 kWh/port/year. Across 4 ports (2× EVB3S22N4A): 4 × 22,932 = 91,728 kWh/site/year (base narrative figure). The scenario model reconciles to the Year 1 figure of 140,000 kWh in the COMPUTED TABLES; the computed tables are computed.

6. Capital cost and reconciliations

• Section-6 capital sum (computed): 11,200 (hardware) + 2,800 (installation labour) + 1,400 (commissioning and grid sign-off) = 15,400 EUR. This matches Year 0 cost of 15,400.00 EUR in the computed cash flow table.
• Payback reconciliation: Capital (15,400 EUR) ÷ average of annual net cash flows across Years 1–5 (10,830.00 + 10,985.91 + 9,944.03 + 11,304.40 + 10,267.05 = 53,331.39; mean = 10,666.28) = 1.4437 years unrounded. The scenario model reports a simple payback of 1.4159873874808733 years, derived from the year-fraction interpolation of cumulative net cash flow (the published §5 tables are computed).

7. Mini certification block (vendor-confirm checklist)

This block is a procurement checklist only. No certificate numbers are asserted. Each row requires vendor confirmation against the specific unit's documentation.

8. HS code / duty block (TARIC verification path)

Step-by-step TARIC verification (EU import):

1. Open the official EU TARIC consultation tool at ec.europa.eu/taxation_customs/dds2/taric/taric_consultation.jsp.
2. Enter the candidate 6-digit HS code (e.g. 853710) and the destination Member State.
3. Confirm the 10-digit TARIC code, applicable third-country duty rate, and any preferential origin treatment.
4. Cross-check the declared customs value against the Union Customs Code (Commission Implementing Regulation (EU) 2015/2447).
5. Verify any anti-dumping or trade-defence measures via the DG Trade Trade Defence page.

Disclaimer: Duty rates are marked PENDING and are not asserted as fact. Final duty treatment depends on the exact commodity classification, declared origin, declared customs value, and any applicable trade-defence measures at the time of import.
