A New York Times article (August 26, 2011) describes the incompatible standards for fast charging 480 volt chargers that can charge a Nissan Leaf in half an hour. The issue is that standards for these fast chargers are not set, thus creating problems with charging cars on the go.  While the Society for Automitive Engineers has a standard for the 120 volt home chargers, will delays in introducing standards for fast chargers dampen growth of this industry ? Is there any strategic reason for auto manufacturers to resist common standards for battery charging ? Will there be an incentive for manufacturers of these charging stations to have their own proprietary standards ?
