Ultracapacitors [UC], also called Supercaps, have been introduced into the marketplace in relatively large volumes since 1996 and continue to experience steady growth. In recent years UC have become more accepted as high power buffers for industrial, aerospace and transportation applications as standalone pulse power packs, or in combination with conventional lead-acid batteries and advanced chemistry batteries. The automotive industry is creating new demands for electrical power within vehicles - both as part of the power train in hybrid and electric vehicles, and to power the increasing level of electronic components in cars. Cars are becoming more sophisticated, evolving towards an intelligent electrically-powered platform with many more subsystems and accessories, requiring a substantial increase in the need for electric power. A stable 14V board net is required to ensure a continuous and always adequate board net performance. Several UC based innovative board net and hybrid drive train concepts have been designed with consistently positive results with regards to efficiency and consumption. UC, thanks to their specific properties, are ideally suited to overcome the prospective energy requirements of vehicles. This paper presents recent advances in UC technology with regard to the use in automotive applications, and discusses start-stop, micro hybrid and board net stabilization architectures using UC actually in development at OEMs and Tier1s.
