GM: Let's Hash Out Open Plug-In Car Standards

Tony Karrer Delicious EVdriven

We noted in December that the Society of Automotive Engineers, or SAE, was working to update standards for the interface between plug-in electric cars and the grid, and planned to agree on a set within months. And for this ecosystem to be robust, there must be commonality, especially when owners are plugging into the electrical grid.

Using the PHEV (Plug-In Hybrid Electric Vehicle) to Transition Society Seamlessly and Profitably From Fossil Fuel to 100% Renewable Energy

Green Car Congress

At present, PHEV technology alone is equipped to improve the current electric grid. The car can refuel during periods of low demand on the grid, and if equipped with a bi-directional charger, can actually replenish the grid with excess energy gleaned from a renewable resource. For an extended discussion see Appendix C).

GM Expects Chevrolet Volt to Deliver 230 mpg in City Driving Based on EPA Draft Methodology

Green Car Congress

So, a vehicle like the Volt that achieves a combined triple-digit fuel economy is a game-changer.The key to high-mileage performance is for a Volt driver to plug into the electric grid at least once each day. —GM GM CEO Fritz Henderson. The EPA anticipates issuing guidance and/or a rule this year. Both use the J1772 connector. Resources.

CalCars and PHEVs Frequently Asked Questions

Tony Karrer Delicious EVdriven

A January 2007 Pacific National Laboratory study shows that if we woke up tomorrow and all our vehicles could plug in, todays grid could support more than three-quarters of them charging at night without building a single power plant. But its monumentally less pollution , even on the national (half-coal) grid.
