Trough battery spaces between the plates (the troughs) were filled with dilute sulfuric acid. So long as the box was not knocked about, there was no risk of electrolyte spillage. 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.
Battery electric vehicle CNG bus, and produces 44 percent less carbon than CNG. For most of the 20th century, the majority of the world's battery electric road vehicles were British milk floats. The 21st century saw the massive development of BYD electric trucks. In March 2012, Smith Electric Vehicles announced the release of the Newton Step-Van, an all-electric, zero-emission vehicle built on the versatile Newton platform that features a walk-in body produced by Indiana-based Utilimaster. BYD supplies DHL with electric distribution fleet of commercial BYD T3. A battery-powered electric car is an automobile which is propelled by electric motors. Although electric cars often
