Charging Wireless Will Become Standard EV and Plug-In Hybrids
its electric car (EV: electric vehicle) and hybrid "plug-in", it also raises new technology. In this case the system is recharging the battery. According to analysts quoted Wardsauto.com, wireless charging system (wireless charging) will become standard. The reason is, how to fill it more practical and certainly more enjoyable user.
It was presented by Laura Marino, Deputy Director of Electronic and Electrical Systems Research Oak Ridge National Laboratory to the several hundred engineers who followed Automotive Power Electronic conference, organized by SAE France, SIA, April.
"Imagine a mother with three children after shopping with many tetengan in hand! Definitely not going to remember to install stekker his car into a power outlet in the garage, "said Marino.
With this charging system, no need to use cables, plugs and electrical sockets. Charging is done "hands-free". Cars parked on top of the charger or power source, then charging will take place by itself.
Further, the system can be used or installed in the garage, in the parking lot even in places where bus, taxi or shuttle vehicles between hung waiting for passengers. Includes when the car is running on the road surface is installed with this charging system.
Induction vs. Resonance
Actually wireless battery charging system while still in development stage. Today there are several wireless systems are developed, namely induction, the successor of power or energy (energy / power coupling), resonance, successors magnetic resonance (resonant magnetic coupling).
Wireless induction system created by the Oak Ridge could move the 5 kW power with a slit 25.4 cm (1 inch) and above 90 percent efficiency. The weakness of this system, coil wire or coil used to generate heat and electric power will further reduce the efficiency of work (compared with direct contact). In addition, the system is more complicated because it is equipped with electronic control. The price was so expensive.
While the system developed WiTricity resonance using magnetic resonator, claimed to be able to move power more efficiently and a greater gap
