Industry leadership meets at the Society of Automotive Engineers (SAE) in Detroit to hash out standard
Imagine an automotive industry in which every fuel tank required a custom gas nozzle to fuel it. Or imagine, for a moment an electronics industry with a plethora of wall plugs, with builders scrambling to adapt homes to particular plug designs. That is precisely the dilemma the electric vehicle industry is in, as Ford, GM, and Chrysler gear up for large scale production of electric vehicles.
Without a standardized plug for all these vehicles, it will be hard to put a charging infrastructure in place and hard to sell the EV models like the 2010 Chevy Volt. So industry leaders are converging on Detroit, Michigan for a special Society of Automotive Engineers (SAE) conference, which looks to hash out an industry standard. The group, already formed, is known as the SAE J1772â„¢ Task Force. Composed of industry experts, they will define one of the most frequent user interactions with the car in years to come -- plugging it in for recharging.
While variables like weather and voltages at the plug may differ, the common factor that the standard will enact is a common plug design. Gery Kissel, an Energy Storage Systems Engineering Specialist at GM, and engineer with the group writes, "With SAE J1772™, we’re defining what a common electric vehicle conductive charging system architecture will look like for all major automakers in North America, but more importantly, we’re working to resolve general physical, electrical and performance requirements so these systems can be manufactured for safe public use."
The SAE is also devoting time and money to research into battery electrochemistry, optimal battery-size and state of charge, and lifecycle, but the charging interface is their biggest priority, as it represents a make-or-break point for the fledgling market.
Mr. Kissel writes, "Think about it, if you have no reservations or confusion about charging your vehicle, you’re probably going to be more likely to drive one. Drivers shouldn’t have to worry about electromagnetic compatibility, emission and immunity when they need to plug-in - that’s what engineers like me get paid to do."
He says that by the end of the summer the SAE should have a standard worked out. Top priorities will be safety and efficiency. With this new standard in place, the domestic electric vehicle industry will at last get the green light to proceed.

Agreement reached on common 'plug' for electric cars: firm
April 19th, 2009
Leading automotive and energy companies have reached agreement on a common "plug" to recharge electric cars, a spokeswoman for German energy company RWE said Sunday.
The three-point, 400-volt plug, which will allow electric cars to be recharged anywhere in a matter of minutes, is set to be unveiled Monday at the world's biggest industrial technology fair in Hanover, northern Germany.
"A car must be able to be recharged in Italy in exactly the same way as in Denmark, Germany or France," an RWE spokeswoman, Caroline Reichert, was quoted as saying in an edition of Die Welt to appear Monday.
She gave no timeframe for the introduction of the plug, saying that talks between the companies were ongoing.
The agreement on a common standard for the plug comprises several major automakers, including Volkswagen, BMW, Ford, General Motors, Fiat, Toyota and Mitsubishi.
Energy firms signed up to the accord include Eon, Vattenfall, EDF, Npower, Endesa and Enel.
Berlin hopes that one million electric cars will be on the road by 2020. RWE and Daimler launched a pilot project in Berlin in September.
The development of a common plug is a major step towards the mass production of electric cars, Reichert told Die Welt.
