Toyota will begin the testing of a new wireless battery charge system, based on magnetic resonance technology. The tests will begin at the end of February in Japan and it is estimated to last a year. Then they will extend to the United States and Europe. This technology can be used in those vehicles with electric motor: both plug -in hybrids and electric vehicles. With this system the battery charge process will be simplified and facilitated.
How does the battery charge process work through magnetic resonance?
Electricity will be transmitted thanks to the magnetic resonance resulting from the intensity changes of the magnetic field between a coil on the parking floor, which transmits, and another in the vehicle, which it receives. The system will reduce the efficiency decreases that can cause a bad alignment between the vehicle and the load surface or the height differences between the transmitting coil and the receiving coil.
This new load system will minimize the magnetic interference of nearby equipment. In addition, the transmitter coil will carry a structure that will resist the weight of the vehicle during parking maneuvers. The system will work both in online and battery parking lots.
To facilitate the maneuver and that the driver appears in an optimal position for the battery charge system, Toyota has created a new parking assistance application that indicates where the transmitter coil is located in the parking space. This function is combined with the intelligent parking system - 'Intelligent Parking Assist' (IPA) - of Toyota.
The wireless vehicle load test process
three Japanese plug -in hybrid vehicles will be responsible for carrying out the verification tests. In them, user satisfaction, the ease of use of the system, the frequency with alignment errors, frequency of loading and the use of the timer load will be evaluated.
The results will serve to improve technology for a future launch to the market, since Toyota believes that this technology will help promote the use of hybrid and electric vehicles, by simplifying the loading process.
