Assumptions behind these numbers
- Model assumptionStart charge 100%, arrive with 15% in reserve, charge up to 80% at each stop.
- Model assumptionUsable battery: 100% of each vehicle's listed capacity (the listed capacity may be gross or net; no correction is applied).
- Model assumptionSpeed: consumption starts from each vehicle's listed real-world efficiency, times a speed factor of 1.00 (1.00 = no speed adjustment).
- Vehicle dataWeather: each vehicle uses its own hot, normal and cold factor from our vehicle data, so consumption = efficiency x 1.00 / factor. Hot is 25 °C and above, normal is 10-25 °C, cold is below 10 °C.
- Model assumptionCharging speed: average power = min(vehicle peak kW, 150 kW cap) x 0.60 taper, plus 5 min per stop.
- MethodRange, energy and cost all use the same consumption figure. Energy is measured at the battery; charging losses are not included.
- MethodCharging stops are estimated from range and the charging window. They are not verified charging stations.
- Market dataCost: not shown, because no electricity market price is available for South Korea.
- Market dataCO2: energy x grid average carbon intensity of 368 g/kWh (South Korea, Ember Climate, Monthly average, April 2026, older than 45 days, last available value).

The route is not cross-border, remaining entirely within South Korea, and the climate in Incheon is normal, so no cold-weather range reduction is expected for the initial leg. However, the journey likely involves a ferry crossing to Jeju, which is not reflected in the drive duration and may add logistical complexity. EV drivers should anticipate a mid-route charging stop, as the distance exceeds the typical range of many electric vehicles, and verify ferry compatibility with their vehicle's charging needs.
