Audience: B2B procurement / fleet-facility managers (AU). Equipment family: Huawei FusionCharge 40 kW DC dispenser (model FusionCharge, public datasheet via Huawei Enterprise AU product page) with a Sungrow IDC30E/IDC40E-class shared 40 kW stack architecture; CCS-2 connector per IEC 62196-2. Horizon: 8 years. Evidence date: model run 2024-09-01. Limitation: figures are deterministic outputs from the tradvolt scenario TCO model under the bounded assumptions listed in §2; they are not a forecast of vendor pricing.
NPV = -1,061,372 AUD over an 8-year horizon at an 8.00% discount rate. Discounted payback = none. Simple payback = none. The EV fleet achieves 0.2464 AUD/km against an ICE comparator at 0.3410 AUD/km, a per-km saving of 0.0946 AUD and 1,211,300 AUD over the horizon — but only because the EV comparator in the model also attracts upfront capex, diesel, and maintenance. Standalone on the hub cash-flows, the NPV is negative and the project does not pay back within 8 years on the modelled demand-charge and tariff stack.
| Metric | Value | Reading |

| IRR | -0.1522 | Below hurdle |

| TCO per km — EV (AUD/km) | 0.2464 | Lower than ICE |
| TCO per km — ICE (AUD/km) | 0.3410 | Comparator |

Procurement reading: do not treat the hub as a standalone revenue project on these inputs. Treat it as an enabler whose economics depend on displacing the modelled ICE comparator's diesel, maintenance and capex lines.
This page models a 40-port DC fast-charging hub co-located with an Australian road-freight logistics depot, sized for mixed-fleet duty (last-mile vans + heavy-duty short-haul tractors). The hub is grid-connected at 415 V three-phase with a 2 MVA service upgrade. Behind-the-meter solar and storage are out of scope. Equipment basis: Huawei FusionCharge 40 kW DC dispenser (dual CCS-2, OCPP 2.0.1-capable) backed by a Sungrow IDC30E/IDC40E-class shared 40 kW power module architecture; certification scope per §7.

The published model outputs above (§4, §5) are the computed figures. The earlier draft's hand-computed per-port PV cells (106,433 / 85,050 AUD/port) used a different scope (hub-only cash flow without the EV-vs-ICE comparator) and do not reconcile to the scenario model. They are removed. The sensitivity table from the prior draft is removed for the same reason.
| Tag | Description | Daily energy throughput | Idle / standby profile |
|---|---|---|---|
| BASE | Mixed light commercial vehicles, 2 shifts | 4,800 kWh/day | 18 hrs/day low duty |
| PEAK | Freight-heavy duty cycle, 24/7 rotation | 8,200 kWh/day | 6 hrs/day low duty |
Both scenarios are run against CapEx ±15%, Opex ±20%, and utilisation ±25% inside the scenario model. The model's published sensitivity output is the binding figure; scenario text below is descriptive only and does not re-introduce hand-computed PV cells.
