The technology, called ELFA, is a diesel-electric hybrid concept that combines mobile power supply modules, such as diesel generator sets and energy-storage devices, allowing the energy produced during braking to be stored, whereas in conventional city buses, braking energy is converted into heat and lost.
ELFA technology converts this energy into electrical energy fed into energy storage devices like high-performance capacitors and batteries. The stored energy then is reused during start and acceleration.
Depending on the storage capacity of the system, the bus can also be driven purely electrically, without emissions, especially in inner city areas. A smart move for Viet Nam's pollution-choked commuters!
