Swapping Rather Than Recharging

With Tesla now promising 90-second battery swaps, a “recharging” tactic first tried by Shai Agassi’s A Better Place, an Israeli company now in bankruptcy, the long recharging period for electric vehicles may be overcome.  Car companies, though, are not the only entities looking for ways to get unplugged. Presented at the 20th Congress of the “Club des Villes et Territoires Cyclables” in Nice, the Alter Bike is a collaboration of three French companies: Cycleurope, a specialist in bicycles;  Pragma Industries, a specialist in hydrogen; and Ventec, a specialist in battery management. They tout the advantages of this different approach to electrifying two-wheelers – an approach that seems to have applications even in electric flight. “No more charging time, no need …

Qualcomm is best known for its quirkily-named Wi-Fi and other wireless communications technologies; ETHOS®, Haystack®, and Gobi®, for starters.  Relatively low-powered, they allow notebooks and smartphones access to broadband connectedness. Qualcomm has now expanded its reach, and its power, to inductive charging for electric vehicles.  Its wireless electric vehicle charging (WEVC) technology, HaloIPT will first allow wireless recharging of electric vehicles which park over a “sweet spot” that has the capability of sending power “over an air gap of hundreds of millimeters while still maintaining high-energy transfer electricity,” according to the company. PCWorld reports that Halo’s inductive “WEVC can transfer up to 3.5 kilowatts of power at greater than 90 percent efficiency – that’s as good as, or even better, …

Having recently been allowed a test drive in a Nissan Leaf , in which the late autumn leaves falling on the car made more noise than the car, I was taken by the quiet, the reasonable performance, and general sense of how much more refined everything is than on my well-worn 1995 internal-combustion vehicle.  Cars are indeed getting better, but an issue remains with electric cars and airplanes – range.  The Nissan representatives, a lively bunch of presenters who took prospective drivers through a “pre-flight” education program, admitted that shortcoming, and promised a coming series of charging stations dotting the I-5 from Canada to Mexico at 100-mile intervals, the demonstrated range for the Leaf. Israeli entrepreneur Shai Agassi has come up …
