Generation mode
A version of the TM4 SUMO HP HV900 is also available with control algorithms that are optimized for generation application where continuous power generation is the main operating mode.
The efficiency of the system reaches 95% and has been developed to match the efficiency of a diesel engine, which is instrumental to optimize fuel savings. In a series-hybrid, the combined use of the electric traction system, the optimized gen-set and electrified accessories can result in a minimum 50% fuel economy compared to a conventional vehicle.
