Battery electric vehicles (BEVs) which are practical for the vast majority of daily use exist. Examples are the
Mitsubishi iMieve &
Nissan Leaf. For the small proportion of longer journeys, there is a workable solution:
Tesla Model S. The only problem is that the shear number of cells required for a long range BEV is expensive. In every other respect, all of the problems of a long range BEV have been solved. And this is in no way a marginal solution: the
Tesla Model S is the best car Consumer Reports has ever tested.
Essentially, the range problem is reduced to getting approximately the same amount of energy as in a Model S into a BEV for substantially less money. Elon Musk has said that the Model E mass market car available, "
Hopefully 2016, but I would say no later than 2017," will have a
battery cost 30 to 40% less per killowatt hour than the Model S.
Now a joint venture from Bosch, GS Yuasa, & Mitsubishi is making a major development effort:
