A report in PCmag.com (June 21, 2013 http://www.pcmag.com/article2/0,2817,2420802,00.asp) describes a demonstration of a 90 second battery swap by Tesla, thus offering consumers the choice of waiting and getting free battery charging or paying close to the price of tank of gas and getting 90 seconds swap. The associated video records normal gas tank fill up times of 4 minutes. Is speeding up battery charging key to expanding demand for electric vehicles ? Will the opening of dedicated (incompatible) charging stations by Tesla and other electric vehicle manufacturers slow the overall expansion of the electric vehicle industry ? Given the environmental benefits of electric cars, should the Federal government coordinate standard setting for charging these vehicles to prevent the unnecessary establishment of duplicate retail charging stations by manufacturers, or is the competition an effective mechanism to develop solutions that customers prefer ?
