Gasoline Range Extender 35–45kW BG-RES-35-45G

The Gasoline Range Extender 35–45kW covers two closely related models, representing the upper tier of DSM’s mid-range gasoline extender lineup. Engineered specifically for electric buses, coaches, larger light commercial vehicles, and specialty municipal platforms, these systems deliver sustained auxiliary power across extended duty cycles. Both utilize EU-VI compliant 4-cylinder gasoline engines — the QR472WB with a 1.2L displacement and the A151A1 with a 1.5L — at 540 Vdc output voltage.

These systems excel in bus and coach applications where passenger comfort demands low noise and smooth power delivery. The fully validated three-speed noise management system and integrated thermal management for both the engine and generator ensure quiet, thermally stable operation even during prolonged high-load scenarios such as uphill route segments or air-conditioned operation in summer heat.

Both models feature the standard 5-in-1 modular architecture (IC engine, ECU, generator, GCU, RCU with wiring harnesses), dual output control modes, and comprehensive power battery protection logic. GPRS remote tuning and on-line CAN 2.0 calibration tools are available as options to support fleet-scale deployment and ongoing maintenance optimization.

For operators stepping up from lighter platforms, the Gasoline Range Extender 20kW and Turbo Diesel Range Extender 20kW provide entry points into the DSM mid-range lineup. For the heaviest commercial vehicle applications, the Heavy-Duty Diesel Range Extender 75kW delivers the next level of output.
