Electric battery common fuels such as gasoline. In automobiles, this is somewhat offset by the higher efficiency of electric motors in converting chemical energy to mechanical work, compared to combustion engines. The usage of "battery" to describe a group of electrical devices dates to Benjamin Franklin, who in 1748 described multiple Leyden jars by analogy to a battery of cannon (Benjamin Franklin borrowed the term "battery" from the military, which refers to weapons functioning together). Italian physicist Alessandro Volta built and described the first electrochemical battery, the voltaic pile, in 1800. This was a stack of copper and zinc plates, separated by
Who Killed the Electric Car? either unaware that an electric car was ever available to try, or dismayed that they could no longer obtain one. In a bit of an unexpected turn, the film's sole "not-guilty" suspect is batteries, one of the chief culprits if one were to ask the oil or auto industries. At the time GM's EV1 came to market, it came with a lead acid battery with a range of 60 miles. The film suggests that since the average driving distance of Americans in a day is 30 miles or less, for 90% of Americans, electric cars would work as a daily
