HEVS: Where were we at EVS-1 in 1069 at ISATA 17 in 1984; Where are we today? where will we be in 2014?

摘要

Thirty years ago, at the first (International) Electric Vehicle Symposium, EVS-l, there was only one reference to an HEV. Fifteen years ago, at ISATA 1984 in Milan, I presented a paper on a novel bybrid that had been built and tested (one of twopapers on HEVs). Today, at ISATA'99 there are entire sessions on HEVs; and the TOYOTA Prius, a parallel hybrid, is selling successfully in Japan. Reviewed (briefly) are the basic characteristics of HEVs. As early as 1976 the USA government had tested anHEV with low emissions and excellent specific fuel consumption, but decided that the HEV was not "the way to go" with their hundreds of millions of dollars for research in clean car technology. Why are HEVs suddenly the "great hope to reduce air pollution and fuel consumption in road vehicles"? What can we EXPECT realistically in fifteen years from now at the 47th ISATA? The questions are answered from the viewpoint of 30 years of experience with HEVs.
