History of the battery his iron scalpel, the leg twitched. Galvani believed the energy that drove this contraction came from the leg itself, and called it "animal electricity". However, Alessandro Volta, a friend and fellow scientist, disagreed, believing this phenomenon was caused by two different metals joined together by a moist intermediary. He verified this hypothesis through experiment, and published the results in 1791. In 1800, Volta invented the first true battery, which came to be known as the voltaic pile. The voltaic pile consisted of pairs of copper and zinc discs piled on top of each other, separated by a layer of cloth
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
