Electric bus controlled via antenna

Volvo Technology Japan Co., Ltd. And Nippon Dengyo Tools (Japan) has successfully tested wireless energy transfer technology, very suitable in practice to apply to passenger cars (buses) and electric trucks, clean and ecologically clean.

Buses controlled by antennas will soon be available.

Japanese experts have invented high-efficiency antennas (84% efficiency) to transfer energy through the air. They also plan to install this antenna at a public parking lot, park, street light, etc. It will not be necessary to continuously monitor the battery charging level or use large capacity batteries on trucks. .

This achievement of Japanese experts is very meaningful. It was previously thought that the development of high-frequency energy generators required a lot of time. In fact, most modern wireless systems that transmit tens of watts of power, even the most modern, only a few meters away will lose more than half of their energy.

It was the first Japanese who succeeded in raising the power transmission efficiency from 40 to 80%. Meanwhile, in the testing phase, transmitting electricity through antennas to energy vehicles with a capacity of less than 10 watts was successful at a distance of 4 to 6 meters.

The efficiency of converting electricity into very high microwave radiation has allowed the transfer of energy with small losses. This invention opens a great prospect for wide application in many industries. For example, for electric cars, reserve enough electricity so that the car can run 150-300km after one charge.
