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 to plug your bike into an electrical outlet! The Alter Bike uses hydrogen in a fuel cell: an existing technology in some cars, it can create electricity while emitting only H2O, in other words water.” “Refueling” looks like changing an oil filter …

Charging Your EV on the Move

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, than wired charging.  Instead of plugging in the EV to a charging station, the car will have a charging plate attached to its chassis.  A charging mat, placed above or below the pavement, magnetically transfers power to the vehicle through …
