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 vehicles today use an electric battery, consisting of electrochemical cells with external connections in order to provide power to the vehicle. Battery technology for EVs has developed from early lead-acid batteries used in the late 19th Century to the 2010s, to lithium-ion batteries which are found in most EVs today. The overall battery is referred to as a battery pack, which is a group of multiple battery modules and cells. The battery pack powering modern EVs can have as little as 96 battery cells to as many as 2,976 cells. Electric cars have traditionally used series wound DC motors, a
