In continuous use in mountainous terrain, up to 400 kWh/100 km is possible, but only with a cooling system
Fuel consumption of an 18-meter articulated bus
The energy consumption of an 18-meter-long electric articulated bus (e-bus) typically varies widely, depending on the model, passenger load, terrain, and heating/air conditioning.
Average values:For efficient models, consumption is often cited as approximately 1.1 to 1.3 kWh per kilometer (110–130 kWh/100 km). Higher values: Under more demanding conditions or with older models, consumption can reach 2 to 3 kWh per kilometer (200–300 kWh/100 km).
Comparison:By comparison, a standard 12-meter electric bus consumes an average of about 100 kWh/100 km.
Examples: BYD 18m: approx. 307 kWh battery capacity for a 230 km range (approx. 1.33 kWh/km). Ebusco 18m: approx. 414 kWh battery capacity, often very efficient. Daimler eCitaro G : Batteries for articulated buses often range from 198 to 441 kWh.
Factors influencing consumption: Energy consumption is heavily dependent on the use of the “Scandinavian package” (heating, insulation) in winter. Similarly, articulated buses consume more energy than standard buses due to their higher weight (often over 18 tons curb weight).
Average: approx. 1.3–1.8 kWh per kilometer (130–180 kWh/100 km). Articulated buses consume about 20–35% more energy than 12-meter buses due to their greater weight and larger surface area (heating/cooling).
Factors influencing consumption:
Climate control (winter/summer):The biggest factor. Consumption increases significantly, especially when heating in winter, often 6 to 29% above the reference value. Driving style:Regenerative braking (brake energy recovery) has a major impact. Experienced drivers can reduce consumption by up to 0.2 kWh/km. Topography:Hilly routes increase consumption.
