ZEM Evolution, a new Italian manufacturer of buses, is currently developing a new range of electric and hybrid vehicles, including a version powered fuel cell with hydrogen, as reported Busworld portal.
The company, formed last year in Brescia, is headed by mechanical engineer Pierpaolo Fusari, founder of EFA (Eco Power Technology), a manufacturer of hybrid buses.
Recently, ZEM Evolution unveiled designs for two buses (between 8 and 10 meters long) and two chassis for refuse collection trucks.
“Plans are to begin production in 2011,” Fusari announced, adding that the vehicles have no comparison ZEM Evolution in Europe regarding the materials used. “An aluminum frame forms the base of the vehicle body, integrally constructed,” explained Fusari.
Regarding the technology used in the powertrain, ZEM has partnered with various vendors to provide different hybrid versions. Another interesting issue is the use of ultra capacitors in the range of ZEM products, ensuring that all hybrid versions are powered by either a microturbine or fuel cell, used to charge ultra-capacitors and batteries with energy. Finally, the system of energy recovery during braking allows buses to reach about 300 km of autonomy.
