Tradvolt › Use cases › EVSE › Mining depot (PL)
Answer / verdict. For a 480 kW DC EVSE (reference SKU tv-evse-dc-480kw) sourced from China and landed at a mining depot in Poland, the scenario model over a 25-year horizon at 8.00% discount reports NPV = €580,708, discounted payback = 0.0 yr, simple payback = 0.0 yr, TCO/km EV = €0.080 vs ICE = €0.256, savings/km = €0.176, and savings over horizon = €1,760,000. Limitation: all CapEx line items (capex[0..9], replacements[0]), residual value and opex.fixed were dropped from the scenario, so PV of costs is €0 and the payback reads 0.0; the benefit side is driven entirely by EV-vs-ICE operating-cost delta on a bounded fleet assumption (see §4 model defaults). Evidence date: 2026-09-21. Duty, third-country tariff and Polish import VAT must still be confirmed on the EU TARIC query for the Polish national line before order placement.

Under the bounded model defaults on this page, NPV = €580,708 over 25 years at 8.00 % discount, TCO/km EV = €0.080 vs ICE = €0.256 (savings €0.176/km, €1,760,000 over horizon). PV of costs is €0 by construction because CapEx lines were DROPPED-ITEM; figures are not a quote.
Verify the exact 10-digit CN/HS national line and applicable third-country duty and Polish VAT on the EU TARIC query for Poland. No rate has been hardcoded.
CE marking under applicable EU directives is the baseline. Evidence against IEC 61851-1 and IEC 61851-23 (IEC) is typically required for conductive DC charging. ATEX 2014/34/EU applies only when the unit is installed in a classified zone — confirm with the OEM variant and the site safety officer.
Simple payback is undiscounted cumulative benefit ÷ cost; discounted payback applies the 8.00% factor. Both report 0.0 because CapEx line items were dropped; replace the DROPPED-ITEM inputs before any procurement decision.
No. Final pricing depends on configuration, Incoterm, target certifications and destination. Submit an RFQ.
ATEX 2014/34/EU applicability is site- and variant-specific. Confirm zoned area classification with the site safety officer and request an ATEX-rated OEM variant if required.
Typically: commercial invoice, packing list, transport document (bill of lading / airway bill), CE technical file reference, and the correct HS classification on the EU TARIC portal (Poland). Confirm any additional requirements with a licensed customs broker.
