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 1,155-kilometer drive from Yokohama to Kumamoto, with an estimated driving time of 896 minutes, requires careful planning for EV drivers despite the route staying entirely within Japan. Although both cities have a normal climate, which avoids extreme cold-related range reduction, the journey passes through varied terrain that can impact efficiency. The drive is not cross-border, simplifying logistics. With a typical EV range of 300–400 kilometers, most drivers will need at least three charging stops, each adding 20–40 minutes, extending the total trip time beyond the 896-minute drive duration.
