Delphi has recently demonstrated to the outside world the research and development results of its wireless charging technology for in-vehicle electronic devices.
It is understood that wireless charging technology cited, derived from wireless power transmission technology, is the use of magnetic resonance in the air between the charger and the device to transfer the charge, coils and capacitors in the charger and the device to form a resonance between the energy efficient transmission Technology.
The wireless charging technology for electronic devices in cars not only does not require the use of a large number of complicated charging lines, but also can charge multiple electronic devices at the same time. In addition, the system technology can make the driver not need to distract attention to find the charging interface during driving of the vehicle, so as to improve the safety of driving.
Delphi stated that the principle of this technology is the same as that of the electric vehicle's wireless charging technology. Both are charged by magnetic resonance without using any charging cable. The difference is that Delphi has built power resonators in the interior of the car, charging electronic devices inside the vehicle (including navigation systems and mobile phones). The system technology is currently being tested and it is expected to begin mass production in 2014.

The MIT research team published their research results on the website of the American magazine "Science" on June 7, 2007. The research team applied resonance to the transmission of electromagnetic waves and successfully "grabbed" the electromagnetic waves. They use copper coils as electromagnetic resonators, a coil of coils attached to the transmitting power, and another group receiving power. When the transmitter sends electromagnetic waves at a specific frequency, it spreads to the receiver through the electromagnetic field and the power is wirelessly transmitted.
