Wireless Charging Road for Electric Buses new technology
The technology behind the wireless charge or inductive load was discovered by Nikola Tesla in the 1890s and uses an electromagnetic field to transfer energy between two objects. In chargers, an induction coil is used to create an electromagnetic field, while a second induction coil in the charging device is used to take the field energy created and convert back into an electric current that charges the battery . All sounds relatively simple, but the inductive load has been difficult to implement, especially with larger objects, moving objects and objects that are farther away from the loader. These limitations would make urban buses, for example, unlikely candidates to use the technology. However, an Israeli company called ElectRoad announced that it has been developing a new technology (Dynamic Wireless Power Transfer - DWPT) that can drive a vehicle in motion without cables from the road. The results of the first tests were good enough to win the company a $ 120,000 gr...
