Electrical engineering credited with establishing the term "electricity". He also designed the versorium: a device that detects the presence of statically charged objects. In 1762 Swedish professor Johan Carl Wilcke invented a device later named electrophorus that produced a static electric charge. By 1800 Alessandro Volta had developed the voltaic pile, a forerunner of the electric battery In the 19th century, research into the subject started to intensify. Notable developments in this century include the work of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, of Michael Faraday (the discoverer of electromagnetic
Battery electric vehicle Vehicles. In the European Union, on average, between 2009 and 2013 there was a reduction of the electricity Carbon Intensity of 17%. In a Life-cycle assessment perspective, considering the GHG necessary to build the battery and its end-of-life, the GHG savings are 10-13% lower. Although electric cars do not produce any tailpipe emissions, carbon dioxide is still emitted when the electric vehicle is being manufactured. The lithium-ion batteries used in the vehicle take more materials and energy to produce because of the extraction process of the lithium and cobalt essential to the battery. This means the bigger the electric vehicle,
