One of the big stumbling blocks preventing the wide scale acceptance of electric cars is dreaded range anxiety. With an average range of around 100 mi (161 km) per charge, all-electric vehicles still can't compete with more conventional cars – especially if lights, windscreen wipers, or air con are needed. To level the playing field a bit, Fraunhofer is working on a new battery design that could increase an electric car's range to 1,000 km (621 mi). Electric cars don't have a single battery, but a collection of battery packs made of hundreds or thousands of individual battery cells that are packed in and wired together. These separate battery cells each require a housing as well as terminals, wiring, cables, and electronic monitors, which all combine to take up 50 percent of the space of a whole battery pack. Additionally, all those electrical connections sap away current through resistance. In partnership with ThyssenKrupp System Engineering and IAV Autom
