Gasoline Range Extender 20kW BG-RES-20G

The Gasoline Range Extender 20kW steps up the power output to meet the demands of light commercial electric vehicles, small electric buses, and urban transit platforms requiring a dependable auxiliary power source. Delivering 20 kW at 480 Vdc through a 3-cylinder 0.8L EU-V compliant gasoline engine, this system provides a meaningful range extension for battery electric vehicles operating on longer duty cycles or in hilly terrain where energy consumption is higher.

Weighing just 130 kg at L678 × W465 × H575 mm, this unit is engineered for space-efficient installation in vehicle platforms where payload and floor space are at a premium. The dual output control modes — constant voltage and constant power with load following — adapt intelligently to varying drive cycles, ensuring optimal energy delivery whether the vehicle is idling, climbing grades, or cruising at highway speed. The system’s integrated thermal management and three-speed noise management keep NVH levels within acceptable limits for passenger-carrying applications.

For fleet operators requiring diesel fuel capability at this power level, the Turbo Diesel Range Extender 20kW delivers comparable output with superior fuel efficiency at 0.30 L/kW·h. For larger buses or heavier commercial vehicle platforms, the Gasoline Range Extender 35–45kW offers higher output options within the same product family.
