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 Japan.
- Market dataCO2: energy x grid average carbon intensity of 407 g/kWh (Japan, Ember Climate, Monthly average, March 2026, older than 45 days, last available value).

The 306-kilometer route from Saitama to Niigata in Japan presents a manageable drive for most modern EVs, with a total drive duration of 256 minutes. The climate is normal, so no significant range reduction from temperature extremes is expected. The terrain is not specified, but the route likely involves some elevation changes as it crosses central Honshu. Since this is not a cross-border trip, no border charging considerations apply. EV drivers can confidently undertake this trip with a single charging stop, using the abundant en-route infrastructure to reach Niigata without range anxiety.
