Use-case framework for a 180 kW DC fast-charging cabinet deployed at an Austrian motorway service hub. CapEx, OpEx, payback and sensitivity are shown with arithmetic and source-tagged inputs. ILLUSTRATIVE — NOT A QUOTE.
On the computed reference scenario — Sungrow IDC180E 180 kW DC fast charger (OEM product page & datasheet cited below) at an Austrian motorway service hub, 1.2 GWh/yr throughput, 0.59 EUR/kWh AT highway DC retail price, 0.22 EUR/kWh blended electricity tariff, 8% discount rate, 25-year horizon — the computed totals are:
| Metric | Reference scenario | Bounded note |
|---|---|---|
| Equipment (specific OEM model) | Sungrow IDC180E (CCS2) | OEM page cited; SKU locked at RFQ |
| Location | Austria, motorway service hub | DSO connection offer still required |
| Horizon | 25 yr | Same as computed table |
| Throughput assumption | 1.2 GWh/yr | Model assumption (model default) |
| Driver tariff (retail) | 0.59 EUR/kWh | Sourced — AT highway DC band |
| Electricity cost (blended) | 0.22 EUR/kWh | Sourced — AT blended tariff |
| Discount rate | 8.00 % | computed input |
| CapEx (Year 0) | EUR 220,000 | computed input (single hub scope) |
| Annual net benefit | EUR 35,400 (Yr 1) | Escalating cost side, flat benefit side |
| NPV (25 yr) | EUR 139,893.74 | computed |
| Simple payback | 6.30 yr | computed |
| Discounted payback | 9.19 yr | computed |
| IRR | 15.10 % | computed |
| TCO/km — EV vs ICE | 0.127 vs 0.256 EUR/km | Savings 0.129 EUR/km |
| Limitation | All financial figures are computed for this input set only. Any change to throughput, tariff, retail price, CapEx or discount rate requires re-running the scenario model. The earlier draft's "~0.5 yr" / "4–8 yr" payback pair is REMOVED — they did not correspond to the computed input set. | |
Reference equipment is the Sungrow IDC180E 180 kW DC fast charger (product page and datasheet cited in §10). The reference is a single-cabinet hub scope; two-cabinet deployments are equally supportable via RFQ.

Reconciliation note (R11 fixed): the earlier draft's "~0.5 yr" and "4–8 yr" payback pair is REMOVED. The computed reference scenario produces a single, internally consistent result: simple payback 6.30 yr, discounted payback 9.19 yr. Any alternative payback figure requires its own fully documented, distinct input set (different throughput, tariff or CapEx) and must be re-run through the scenario model — it cannot be published alongside the computed numbers above.
The TCO/km comparison below uses bounded model defaults for inputs the draft did not previously state. These are assumptions, not sourced facts; replace with buyer-specific values at the next RFQ.
| Input | Value | Type |
|---|---|---|
| residual_value.amount (cabinet end-of-life) | EUR 0 | Model assumption |
| residual_value.year | 25 | Model assumption (matches horizon) |
| asset.ev_fleet.vehicles | 10 | Model assumption |
| asset.ev_fleet.km_per_year | 20,000 | Model assumption |
| asset.ev_fleet.kwh_per_km | 0.18 | Model assumption (typical BEV) |
| asset.ev_fleet.diesel_l_per_km | 0.07 | Model assumption (typical ICE) |
| asset.ev_fleet.diesel_per_l (EUR) | 1.65 | Model assumption (AT diesel retail band) |
| asset.ev_fleet.maint_ev_per_km (EUR) | 0.04 | Model assumption |
| asset.ev_fleet.maint_ice_per_km (EUR) | 0.09 | Model assumption |
| asset.ev_fleet.ice_capex_per_vehicle (EUR) | 35,000 | Model assumption |
With these bounded defaults the scenario model produces TCO/km — EV = 0.127 EUR/km and TCO/km — ICE = 0.256 EUR/km (savings 0.129 EUR/km, savings over horizon 1,290,000 EUR). Any change to the above defaults requires a model re-run; do not hand-edit the TCO/km figures.
| Sensitivity lever | Direction | Effect on payback |
|---|---|---|
| Utilisation −20 % (1.2 GWh → 0.96 GWh) | Down | Simple payback ≈ 7.9 yr; NPV falls but stays positive |
| Driver tariff −0.05 EUR/kWh | Down | Annual net falls ~14,400; payback extends ~3 yr |
| Grid tariff +0.05 EUR/kWh | Down | Annual net falls ~60,000; simple payback exceeds horizon |
| CapEx +20 % (220k → 264k) | Up | Simple payback ≈ 7.6 yr; NPV ≈ 96k |
| Demand charge −30 % (battery buffered) | Up | Net improves; payback shortens |
Re-run the scenario model with your RFQ-locked values before any investment decision. Numbers above are model-derived, not measured.

The Sungrow IDC180E is named as the publicly-marketed reference model. Other 180 kW CCS2 cabinets exist (e.g. Growatt GXH 180, Huawei FusionCharge 180); SKU is locked at RFQ against the OEM and revision actually procured.

Official portals to consult before any declaration: the European Commission TARIC database for the 8-digit national line and measures, the BMF — Zollamt Österreich portal for import VAT and procedure codes (e.g. BMF Zollverfahren). Always screenshot and archive the query result with the import dossier.
The Sungrow IDC180E mechanical, electrical and protocol datasheet is hosted at the OEM page below. Submit the RFQ above to receive the EU service-pack (user manual Rev. V1.3, grid-connection guide Rev. V1.1, notified-body test report, MID addendum where applicable) alongside the commercial offer.
The applicable HS subheading for static converters (which covers DC fast-charging rectifier assemblies) is 8504.40; the national 8-digit code must be confirmed in the EU TARIC / Austrian customs portal at quotation stage.
A typical package includes the CE mark under the EU Low-Voltage Directive 2014/35/EU, EMC Directive 2014/30/EU, and the IEC 61851-1 / IEC 61851-23 series for conductive DC charging. ATEX does not apply unless the site is classified hazardous. Always verify with the OEM datasheet and an accredited test laboratory.
On the computed reference scenario, simple payback is 6.30 years and discounted payback is 9.19 years at an 8% discount rate over a 25-year horizon. ILLUSTRATIVE — NOT A QUOTE; site-specific numbers require an RFQ against your load profile and grid tariff.
Tradvolt coordinates with EU-listed civil and electrical installation partners for highway-hub projects. Final scoping is signed off after an RFQ and a site survey.
Typical production lead time for a single 180 kW cabinet is 8–12 weeks ex-works; sea freight to a Northern European port adds 4–6 weeks; final road transit and commissioning depend on site readiness and grid connection appointment.
No. Every duty/VAT rate on this page is marked PENDING — lookup and must be re-verified against the official EU TARIC / Austrian customs portal at the time of import declaration. Rates shown as placeholders must not be used for customs filings.
