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 multiple unit RB 46), nowadays the "Glückauf-Bahn" from Gelsenkirchen via Wanne-Eickel to Bochum. In the 1930s an experimental battery electric train ran successfully at Bray. The train's batteries were charged at each station via an overhead pickup. The train reached 60 mph. In Japan, JR East tested a "NE Train Smart Denchi-kun" battery electric railcar from 2009. This vehicle is capable of operating under 1,500 V DC overhead wires or on battery power alone for a distance of up to 50 km away from an overhead power supply. The batteries are charged via the pantograph either when running under an overhead electric
