Arcade-EVSE 4-Port TCO in the EU

Use case for a 4-port arcade-style AC EVSE cluster deployed in an EU commercial venue (mall, hotel, leisure center). Equipment: Sigenergy Sigen EVAC 22 kW (4-port arcade enclosure), installed per Sigenergy installation manual rev. 2025-03. Horizon: 8 years. Discount rate: 4.0% real. Evidence date: 2026-01-12. Limitation: 8-year horizon assumes no mid-life power-module replacement beyond standard preventive maintenance; site-specific DSO reinforcement costs must be confirmed with the operator's DSO. Limitation: no CE/RED/LVD certificate number, no notified body, and no MID/Eichrecht certificate is asserted in this page.

Verdict

Across the base scenario, the 4-port arcade-EVSE cluster delivers NPV = +74,203.24 EUR at a 4.0% real discount rate over an 8-year horizon, with a simple payback of 1.75 years and a discounted payback of 1.85 years. TCO per km is 0.1353 EUR/km (EV) versus 0.3410 EUR/km (ICE), i.e. 0.2057 EUR/km savings, totalling 263,300 EUR over the horizon. Equipment: Sigenergy Sigen EVAC 22 kW (4-port arcade enclosure), installed per Sigenergy installation manual rev. 2025-03. Location: EU-27 commercial venue (mall, hotel, leisure center). Horizon: 8 years. Evidence date: 2026-01-12. Limitation: no CE/RED/LVD or MID/Eichrecht certificate IDs are asserted on this page; figures are audited model outputs, not independently certified. Recommendation: deploy, subject to DSO grid-connection confirmation and member-state tariff-rules review.

Costs and benefits in the table above share one time basis: the simple payback and total undiscounted cost / benefit are undiscounted (nominal-terms series at r = 0%); the discounted payback, NPV, IRR, PV of costs, and PV of benefits are discounted at r = 4.0% real. TCO per km is undiscounted (per-km metric); NPV is discounted. Energy (kWh) column in the cash-flow table is zero on all years because, in the audited model, energy is treated as a benefit line (driver-paid public tariff) rather than a cost line billed to the site; site energy, venue fee, O&M, insurance, and SaaS are netted into the audited 16,160 EUR/yr benefit (see Section 3). TCO per km is an audited model output, not an independently certified figure.

1. Scope and assumptions

The "arcade" form factor groups 4 AC outlets (Type 2, 22 kW each) behind one enclosure with a single upstream AC connection and one OCPP back-office link. The cluster serves short-stay visitors with dwell times typical of a leisure venue. We model a single cluster of 4 ports based on the Sigenergy Sigen EVAC 22 kW (4-port arcade enclosure), installed per Sigenergy installation manual rev. 2025-03 (document title: Sigen EVAC 22 kW Installation Manual, revision 2025-03; torque, SOC, and voltage limits defined in that manual's installation-torque table and DC-bus section). The audited TCO model is the sole source of every EUR figure in this page; no figure may be re-derived or replaced by an outside calculation.

1.1 Model assumption block (explicit bounded defaults)

These inputs are NOT sourced from regulators, OEMs, or customs pages. They are explicit bounded assumptions of the audited model and must be confirmed per project before procurement.

residual_value.amount: 0 EUR (terminal scrap; bounded 0–1,500 EUR depending on enclosure condition at year 8).
residual_value.year: 8 (end of horizon; bounded 7–10).
asset.ev_fleet.km_per_year: 160,000 km/yr aggregate (cluster-allocated; bounded 80,000–240,000).
asset.ev_fleet.kwh_per_km: 0.18 kWh/km (AC delivery; bounded 0.15–0.22).
asset.ev_fleet.diesel_l_per_km: 0.065 L/km (bounded 0.055–0.080).
asset.ev_fleet.diesel_per_l: 1.55 EUR/L (net of energy-tax benefit for fleet diesel; bounded 1.40–1.75).
asset.ev_fleet.maint_ev_per_km: 0.030 EUR/km (bounded 0.020–0.045).
asset.ev_fleet.maint_ice_per_km: 0.090 EUR/km (bounded 0.070–0.110).
asset.ev_fleet.ice_capex_per_vehicle: 28,000 EUR (bounded 22,000–34,000; comparator only, not a direct EVSE input).

2. Inputs table

3. Cash-flow reconciliation to audited table

The audited model consolidates site energy, O&M, insurance, and SaaS into a single fixed-cost envelope of 1,280 EUR/yr (O&M 620 + insurance 180 + SaaS 480) and treats driver-paid public-tariff revenue as the benefit line, net of site energy and venue fee. The table inputs above map to the audited Cost (1,280 EUR/yr) and Benefit (16,160 EUR/yr) columns as follows.

We present a sensitivity grid over the two inputs the venue operator can actually move — sessions per port per day and site-energy price (EUR/kWh). Hardware and install costs are held at base case. Cells show simple payback in years from the audited formula payback = capex / annual net cash flow. Per R4, the audited TCO-per-km figures (0.1353 EV, 0.3410 ICE) are model outputs and are not independently certified; the sensitivity below uses the audited cost/benefit split and is therefore consistent with the NPV and payback in the summary table.

Cells show simple payback in years. The base case (2.5 sessions/port/day, 0.26 EUR/kWh) reconciles to the audited simple payback of 1.75 years. Cells above 0.26 EUR/kWh assume the same audited cost/benefit split with site energy replacing the bounded 0.26 input; cells below 0.26 EUR/kWh hold the public tariff at 0.49 EUR/kWh and reduce only the site-energy component. Cells are illustrative model outputs and must be re-run for the operator's contract.

Checklist — no conformity claimed on this page. The operator must obtain and verify each item with the relevant notified body, calibration authority, or DSO before commissioning. No CE/RED/LVD certificate number, no notified body ID, and no MID/Eichrecht certificate ID is asserted below.

CE marking on AC EVSE per Directive 2014/53/EU (RED) and Directive 2014/35/EU (LVD) — operator to obtain certificate number and notified body ID from OEM; not asserted on this page.
MID / Eichrecht conformity if billed by kWh (member-state specific, e.g., Germany, Austria) — operator to obtain calibration certificate from the competent authority; not asserted on this page.
AFIR-aligned payment interoperability for public use (Regulation (EU) 2023/1804).
OCPP 1.6 / 2.0.1 back-office link (Open Charge Alliance); ISO 15118 readiness optional.
Site electrical compliance per HD 60364 series and local DSO requirements; battery-related obligations under Regulation (EU) 2023/1542 where stationary storage is co-located.

This block is a checklist prompt, not a conformity certificate. Confirm with your notified body and DSO before commissioning.

7. HS code block and duty treatment

HS classification (illustrative; verify with customs broker):

Conjectured HS subheading: 8504.40 (static converters, n.e.c.) — duty rate marked PENDING.
Alternative subheading to evaluate: 8504.40 vs 8543.70 (other machines with individual functions) — both marked PENDING.

Lookup instructions for the operator:

Open the EU TARIC consultation page and search the 8-digit code for the EVSE cluster.
Cross-check with your national customs authority's binding tariff information (BTI) portal where available.
Request a written classification from your customs broker before first import; rates vary by subheading and origin.
Confirm any anti-dumping or surveillance measures applicable to country of origin; for non-EU comparisons, see USITC HTS, UK Global Tariff, Japan Customs, Australian Border Force, South African Revenue Service, Ghana Revenue Authority, and Uganda Revenue Authority.
Freight terms and Incoterms: see ICC Incoterms 2020; freight documents: FIATA; dangerous goods (lithium battery shipments): IATA DGR; wood packaging: IPPC ISPMs (incl. ISPM 15).

Disclaimer: TradVolt does not assert any duty rate as fact. The figures marked PENDING must be confirmed by the importer with the relevant customs authority. Treat all duty outcomes as estimates pending official classification.
