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 539-kilometer route from Seoul to Jeju City presents a unique challenge for EV drivers, as it requires a ferry crossing since Jeju is an island. Both cities share a normal climate, so no significant range reduction from cold weather is expected. Practical implications include the need to charge fully before departure and to account for the ferry transit time, which adds to the total travel duration beyond the stated drive time.
