A comparison of energy-storage devices for use in future automobiles

O'Connell, L.G.

The Transporation Systems Research Program of the Lawrence Livermore National Laboratory (LLNL) conducted a study over a four year period to determine which energy-storage devices and their associated propulsion system are likely to be capable of providing credible alternatives to current type automotive propulsion systems between now and the year 2000. It was found that a complete spectrum of automotive performance levels can be achieved by energy storage automobiles during this time period. These range from automobiles with general-purpose performance equivalent to internal combustion engine (ICE) performance to performance suitable for vehicles with specific missions. These automobiles will likely be more expensive to purchase than their ICE counterparts. Large scale introduction of such vehicles can be constrained not only by the development of energy storage technology, but also by the availability of the required manufacturing capability and service infrastructure.
