Boston Consulting Group says car battery costs will not fall far enough in the next 10 years to allow a massive shift toward electric vehicles.

Although electric-car battery costs are expected to fall sharply over the coming decade, they are unlikely to drop enough to spark widespread adoption of fully electric vehicles without a major breakthrough in battery technology, according to a new study by The Boston Consulting Group (BCG).

The study, released today, concludes that the long-term cost target used by many carmakers in planning their future fleets of electric cars--$250 per kilowatt-hour (kWh)--is unlikely to be achieved unless there is a major breakthrough in battery chemistry that substantially increases the energy a battery can store without significantly increasing the cost of either battery materials or the manufacturing process.
