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 363-kilometer drive from Hiroshima to Kumamoto, with a drive duration of 286 minutes, presents a manageable single-day journey for an electric vehicle driver. The route is not cross-border, simplifying planning as no international charging standards or payment systems are involved. For a typical long-range EV, one mid-route charging stop should suffice, though drivers of shorter-range models may require two brief stops to comfortably cover the distance. The terrain between these two western Japanese cities is varied, with coastal plains and mountain passes, which may moderately increase energy consumption, but the dense station network mitigates any range concerns.
