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 332-kilometer route from Changwon to Seongnam presents a straightforward journey for EV drivers, with a drive time of 253 minutes. The route is not cross-border, remaining entirely within South Korea, and both cities experience a normal climate, meaning no significant cold-weather range reduction is expected. This imbalance suggests that while en-route charging is abundant, drivers starting from Changwon should ensure their vehicle has sufficient range for the initial leg, as the first available station may be some distance from the departure point. A single charging stop of 20-30 minutes would comfortably cover the journey, given the ample infrastructure. The terrain is not specified, but the distance and duration imply mostly highway driving, which is efficient for EVs at moderate speeds.
