Abstract
As ultracapacitors are being used for many years in applications in the fields of transportation, regenerative energy and industry recently they become more and more an important component for automotive engineers. Global pressure on car manufacturers to build low or zero emission vehicles forces designers to review energy storage systems. Therefore an ultracapacitor is used because of significant advantages compared to traditional storage systems as batteries. Besides enabling to size the primary energy system only for average power needs ultracapacitors fascinate by their robustness under challenging thermal, mechanical and electrical conditions. With these characteristics they can form a highly efficient system in combination with other energy storage systems. Maxwell Technologies offers a wide range of components which match to many applications in automotive and other engineering sectors.
