So far, South Korea has allowed electric vehicles to charge batteries using a designated power outlet system connected to a car with a power cable. Wireless EV charging technologies are widely researched but such innovative technology using radio waves of the 85-kilohertz range was prohibited because it can interfere with mobile data communication networks.
Hyundai Motor has tied up with Hyundai Engineering (HEC) affiliated with the auto group and Green Power, a wireless power transmission device maker, to form a consortium, which was allowed to test the wireless charging service on September 9 through a regulatory sandbox policy that exempts regulations on new products or services for a certain period of time, according to the Ministry of Science and ICT.
The consortium would demonstrate its wireless charging service at car showrooms and dealer shops to charge up to 85 Genesis luxury EV sedans. However, the ministry set conditions that the test can be canceled at any time if radio waves emitted by wireless charging equipment are found to interfere with other networks. The test would be carried out by the end of 2021 to collect data and prepare for the commercialization of infrastructure.
The wireless charging infrastructure uses a transmitter installed on the ground of a parking lot space and a receiver module of an EV. When a car moves atop the radio transmitter, the system starts charging.
