EcoSaver hybrid bus

One of the vehicles within EPV's fleet is the EcoSaver, a range-extended electric hybrid bus. The EcoSaver is plug-in sodium battery powered backed up by an on-board diesel or compressed natural gas (CNG) turbine engine. The bus is 100% emissions free. Unlike other hybrid buses, the on-board engine does not run vehicle systems as the battery depletes. Rather the turbine produces electricity that recharges the batteries. The turbines are supplied by

. This first-of-its-kind technology has been deployed in a number of fleets as the process has been tested and improved. Recent testing at the Bus Testing and Research Center at Penn State University show a substantial improvement in fuel economy over traditional buses. The EcoSaver will also be included as part of a national research effort coordinated by th
National Renewable Energy Lab
(NREL) to yield performance data on clean fuel vehicles. The bus plugs in to recharge, and captures energy from regenerative braking technology. The bus does not need proprietary charging infrastructure. Simple industrial grade electrical access is all that is required. The buses can travel more than 100 miles between charges. Numerous demonstration fleets of EcoSaver vehicles have been deployed worldwide since 1998. The DesignLine electric drive system has undergone several major development cycles, with the fourth generation North American system now in production. The EcoSmart is in service internationally in Australia and Abu Dhabi UAE. The Société de Transport de Laval in Quebec, Canada is currently testing the EcoSmart for use in its fleet.
