The technology needed to make electric vehicles viable hasn’t even been invented yet, says Mitsuhisa Kato, Toyota’s global r&d chief.
 “The cruising distance is so short for EVs, and the charging time is so long,” said Kato. “At the current level of technology, somebody needs to invent a Nobel Prize-winning type battery.”
 To deliver the range of a regular gasoline vehicle, today’s EVs need more batteries, which in turn would increase the cost and charging time, he said, calling it a “vicious cycle.”
