Battery electric vehicle City began testing a 66-passenger battery-powered school bus, an all-electric version of the Blue Bird TC/2000. 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 with the air conditioning on. They use Lithium-ion batteries, and consume about . The buses were designed by the Beijing Institute of Technology and built by the Jinghua Coach. The batteries are replaced with fully charged ones at the recharging station to allow 24-hour operation of the buses. In France, the electric
