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 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
