Destination charging at hotels typically uses three-phase AC Level 2 EVSE. An 11 kW unit operates on 400 V three-phase and refills a typical EV overnight or during a half-day guest stay. Portugal's tourism market — Algarve, Lisbon, Porto and the Douro corridor — sees demand from EV-driving visitors from Germany, France, the Netherlands and the UK, where EV adoption is higher.
Reference scope: a 4-star hotel installing 6 charging bays (one EVSE + Type 2 socket per bay), wall-mounted or pedestal, with RFID activation and OCPP 1.6 JSON back-office compatibility.
| Parameter | Value | Unit / Note |
|---|---|---|
| Rated power | 11 | kW (three-phase) |
| Input voltage | 400 | V AC, 3-phase + N + PE |
| Output current | 16 | A per phase |
| Connector | Type 2 | per EN 62196-2 |
| Charging mode | Mode 3 | per EN IEC 61851-1 |
| IP / IK rating | IP65 / IK10 | outdoor / garage |
| Operating temperature | −25 to +55 | °C |
| Network | OCPP 1.6 JSON | over Ethernet / 4G / Wi-Fi |
| Authentication | RFID (ISO/IEC 14443) | or app via OCPP |

The scenario TCO engine assumes 25 kWh/day/bay and €0.18/kWh buy / €0.45/kWh sell. The matrix below holds CapEx (€16,800), 6 bays and fixed OpEx constant and varies utilisation and tariff for the first-year payback check.
| Utilisation ↓ / Tariff (EUR/kWh) → | 0.15 | 0.18 | 0.22 | 0.28 |
|---|---|---|---|---|
| 15 kWh/day/bay | 3.0 | 3.6 | 4.6 | 6.6 |
| 25 kWh/day/bay (base) | 1.7 | 1.36 (base, undiscounted) | 2.0 | 2.7 |
| 40 kWh/day/bay | 1.1 | 1.1 | 1.4 | 1.7 |
Cells assume CapEx of €16,800, 6 bays, sell price €0.45/kWh, fixed OpEx €2,400/yr. Lower utilisation and higher buy tariff extend payback materially.
