Wireless EV Charging Breakthrough: UNIST Team Enables Free Movement
A groundbreaking development in electric vehicle (EV) charging has emerged from Ulsan National Institute of Science & Technology (UNIST). The research team, led by Professor Franklin Bien, has created a wireless power supply system that allows EVs to navigate freely along magnetic fields.
The innovative system, driven by Professor Hajun Lee, generates a wide and strong magnetic field using a network of wires. This enables EVs to maneuver both forward and backward without being tethered to charging points.
The team has overcome practical challenges faced by existing technologies that rely on ferromagnetic materials, which are often costly and lack durability. Instead, they've focused on electromagnetic generators that create circular magnetic fields, facilitating efficient power transfer.
Safety has been a top priority. The team has conducted rigorous verifications, ensuring compliance with IEEE and ICNIRP standards. They've also developed algorithms to optimize the power supply track and receiver design, boosting power transfer efficiency up to 90%.
This breakthrough could revolutionize EV charging, offering unprecedented flexibility and convenience. The team's work paves the way for future advancements in wireless power transfer technology, potentially accelerating the adoption of electric vehicles.
