[Paper Title, Abstract] Charging EV’s efficiently NOW while waiting for the Smart Grid Show AbstractHide Abstract Due to a century of gas-tank / gas-station legacy, most of the focus to date on Electrical Vehicle (EV) charging has been with respect to public charging, charging speed, and impact on the grid. Unfortunately, most of this focus is misguided and simply wrong due to legacy thinking that constrains the consideration of EV’s only in light of the “gas-tank/gas-station model”. The true promise of the EV is its ability to charge anywhere and everywhere from the national grid using the most accessible, and visible ubiquity of the standard 120v outdoor outlet (L1 charging). The often touted issues of availability, time-to-charge, and impact on the grid virtually vanish when one considers that the true promise of the EV is met when it is simply plugged into a standard outlet while parked. A typical American car spends 21 hours or more a day parked. This is plenty of time to maintain even the 100 mile range vehicle always fully charged not only every day, but also at the start of every trip if it is simply plugged in at home and at work or any other place where it will be parked for hours. Similarly, the impact of an EV on the national grid when plugged into 120v is no more than a coffeepot. Whereas the impact of the higher voltage (L2) and fast DC chargers (L3) can draw more power than a dozen homes at once and is a very significant issue (though misguided due to legacy gas-station fill-to-full thinking). Finally, too, the smart-grid can do nothing to manage the load of millions of EV’s if the EV’s are not always plugged in while parked! This paper shows how simple 120v charging (L1) is the most practical, lowest cost, most efficient charging method with the least impact on the power distribution grid for our future of EV’s and can be done Smartly now while waiting for the Smart Grid.
