Electric Bus

The battery electric vehicle, or BEV, is a type of electric vehicle that uses chemical energy stored in rechargeable battery packs. As with other electric vehicles, BEVs use electric motors and motor controllers instead of internal combustion engines for propulsion.

At 2008 fuel prices, battery powered buses are more economical than diesel or gasoline powered buses. The additional cost of the batteries is made up for by the low operating cost in the first half of the typical million to two million mile (three million kilometer) life of the bus.perates nine lectric buses, which have been in operation since 1992 and have carried 11.3 million passengers and covered a distance of 1.9 million miles (3.1×106 km). They were made locally by Advanced Vehicle Systems. Two of these buses were used for the 1996 Atlanta Olympics.Wrightbus has a new a hybrid-electric driveline for the StreetCar RTV which has been developed in conjunction with the ISE Corporation of California and incorporates Siemens ELFA traction components and a Cummins ISL engine. The chassis is built to Wright Group specifications by Swiss trolleybus specialists Carosserie Hess and is powered by Valence Technology lithium phosphate batteries .Beginning in the summer of 2000, Hong Kong airport began operating a 16-passenger Mitsubishi Rosa electric shuttle bus, and in the fall of 2000, New York City began testing a 66-passenger battery-powered school bus, an all electric version of the Blue-Bird TC2000. A similar bus was operated in Napa Valley, California for 14 months ending in April, 2004.The 2008 Beijing Olympics used a fleet of 50 electric buses, which have a range of 130 km with the air conditioning on. They use Lithium-ion batteries, and consume about 1 kW·h/mi (0.62 kW·h/km; 2.2 MJ/km). The buses were designed by the Beijing Institute of Technology and built by the Jinghua Coach Co. Ltd. The batteries are replaced with fully charged ones at the recharging station to allow 24 hour operation of the buses.
