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
Plug-in electric vehicle all-electric vehicle: it uses a gasoline engine and an electric motor for propulsion, but a PHEV has a larger battery pack that can be recharged, allowing operation in all-electric mode until the battery is depleted. An aftermarket electric vehicle conversion is the modification of a conventional internal combustion engine vehicle (ICEV) or hybrid electric vehicle (HEV) to electric propulsion, creating an all-electric or plug-in hybrid electric vehicle. There are several companies in the U.S. offering conversions. The most common conversions have been from hybrid electric cars to plug-in hybrid, but due to the different technology used in hybrids by each
