Diesel Range Extender 15kW BG-RES-15D

The Diesel Range Extender 15kW is the most fuel-efficient unit in the compact category, achieving an industry-leading diesel consumption of just 0.31 L/kW·h. Powered by an EU-IV compliant in-line 3-cylinder 1.2L diesel engine, this system is engineered for light commercial EVs and specialty vehicles that require dependable extended range capability across diverse operating conditions, including extreme cold environments.

With cold-start capability down to -40°C and high ambient tolerance up to 80°C, this is a robust solution for fleets operating in Northern climates, mountainous regions, or industrial settings where temperature extremes are routine. The fully validated thermal management system for both the IC engine and generator, combined with three-speed noise management, ensures smooth, quiet operation in urban or residential delivery applications.

The 5-in-1 modular design — encompassing IC engine, ECU, generator, GCU, and RCU — enables streamlined EV integration, while CAN 2.0 communication and on-line calibration tools facilitate rapid system commissioning and ongoing fleet management. Power battery protection logic activates load-following mode under low SOC (<5%) or low temperature (<-20°C) conditions, protecting battery health and maximizing total vehicle lifecycle value.

Operators seeking a gasoline alternative in this output class can explore the Gasoline Range Extender 12kW, while those needing greater output for heavier platforms should consider the Turbo Diesel Range Extender 20kW.
