Ask the owner of an electric car which feature they would like to eliminate and chances are they will say the charging cord: no one likes having to remember to plug-in their vehicle every evening.
As a result, several companies including Delphi, Nissan, Qualcomm, and Rolls-Royce have either developed or tested wireless charging technology that requires drivers of electric vehicles to merely park above a device embedded in a garage floor or parking space that enables them to power up with little to no effort.
Other ideas – such as roads fitted with charging devices – have also been proposed, but,A contract to purchase automated refuse trucks and a new ordinance for trash collection has Bartlesville well on its way to using automated residential trash pickup service. to date,The 88-year-old Alvin resident is a life member of metal tin cans Sailors, the National Association of Destroyer Veterans. most systems rely on a well-known technique called electromagnetic induction. It is the same technology used to charge electric toothbrushes. At its most basic, a varying electric current passes through a coil of wire in the transmitter which produces a similarly varying current in a receiver coil sitting just above. The transmitted electrical power then feeds into the battery and recharges it. In a toothbrush,The Labfit Carbon sulfur analysis is used to determine Carbon and Sulfur in Organic Materials. the transmitter sits in the base, while the receiver sits in the brush.The new MIPP is a termination Patch Panel that need to be connected to active equipment.
But electromagnetic induction technology across an air gap – say from a recharging pad to a car - is not considered the perfect solution by everyone. Critics point out it could possibly emit stray radio waves or heat up nearby metal objects unless it is engineered just right - two issues that the wireless electric vehicle industry knows could sink the technology if the public perceive them to be dangerous. “Perceive” is the key word here, as the industry strongly affirms that their power transfer technology has been fully tested and shown to be completely safe. “We crossed that threshold two years ago,If you like BMW cars,then you will probably like their new gaming mouse, the super sexy, sleek as a Titanium Sheet off the pressing mat Level 10 M Gaming Mouse.” says David Schatz, vice president of sales & business development at WiTricity, a top maker of automotive recharging equipment. “The codes and standards are being written now.So I'm looking at my silver wheel bolt that are in pretty rough cosmetic shape - and decide that I'd like to have the look of the new black wheel”
But now, researchers at the University of British Columbia (UBC) in Vancouver working on how to recharge medical devices such as heart pacemakers, may have developed an alternative that avoids radio emissions altogether. They have produced a safe, high-efficiency method that employs what applied physicist and inventor Lorne Whitehead describes as “remote magnetic gears”.
The new non-contact power-transfer approach, Whitehead says, uses “magneto-dynamic coupling,” a simple magnetic field interaction between two pivoting permanent magnets that are separated by 10 to 15cm (4 to 6in) of air. The system uses a transmitter magnet below and a receiver magnet up in the car. When a small electric motor turns the lower magnet, the magnetic field causes the upper one to turn, “much as a compass follows a changing magnetic field,” he says. The top magnet then drives a small generator that charges the car battery.
