In a word, batteries. Back in the 1970s the weak link in the national electric vehicle R&D program of the time was the battery. It remains so today. Every few years one research group or another issues a breathless press release about its laboratory "breakthrough" which will revolutionize battery technology (searching the Internet on "electric battery breakthrough" is instructive). There have been advances certainly but they've been more evolutionary than revolutionary. It's not my area of competence but my impression is that current batteries suffer various combinations of too big, too heavy, too little storage capacity, too limited in discharge current, too difficult to charge, too short lived, too dangerous, too environmentally challenging to produce and to dispose, and of course too expensive, which is too bad.
