The car itself charging

In the future, you can comfortably drive an electric car without worrying about recharging it.

Battery charging technology for electric cars is moving from fast charging to battery replacement to wireless charging. But engineers at Stanford University have come up with a better idea: just run the car to charge.

Magnetic resonance technology will help eliminate the anxiety of battery power drivers

According to a report published in the American Institute of Physics' Applied Physics Letters , a panel of experts chaired by Shanhui Fan is studying the technology. They attach steel rolls several meters apart along the highway and equip the electric car with a single coil. When the car crosses the highway, the windings that are attached along the road will charge the car.

It sounds incredible, but in fact, the phenomenon known as 'magnetic resonance interaction' has been proven. When it is tuned to resonate at the same frequency, a coil connected to the current can transfer that frequency to another coil through a special magnetic field.

Five years ago, a team of researchers from the Massachusetts Institute of Technology illuminated a 60-watt balloon with magnetic resonance. Another initiative from the institute called WiTricity has helped to create a wireless power rug for the devices. MIT physicists have also discovered that this efficient method of transmission is safe for humans and animals.

Shanhui Fan and colleagues used a computer model to create a winding system that could transmit 10kW to an electric vehicle. They found that if the winding bends 90 degrees, each roll has a metal plate spaced about 2 meters apart can make wonders. Electrical engineers plan to test the system by using computer simulations in the laboratory and then prototyping to ensure that the system can operate efficiently.

Notice the battery is obsessed with electric cars, but with the technology of magnetic resonance, it's time to get rid of that fear.
