Trough battery Trough battery The trough battery was a variant of Alessandro Volta's Voltaic Pile and was invented by William Cruickshank c. 1800. Volta's battery consisted of brine-soaked pieces of cloth sandwiched between zinc and copper discs, piled in a stack. This resulted in electrolyte leakage as the weight of the discs squeezed the electrolyte out of the cloth. Cruickshank solved this problem by laying the battery on its side in a rectangular box. The inside of this box was lined with shellac for insulation, and pairs of welded-together zinc and copper plates were laid out in this box, evenly spaced. The
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
