Hyundai-Kia America Technical Center, Inc., (HATCI) and Mojo Mobility, Inc., a wireless power technology company, have been awarded a funding grant from the U.S. Department of Energy’s (DOE) Office of Energy Efficiency and Renewable Energy (EERE), Vehicle Technologies (VT) program to research and develop a system capable of fast charging an electric vehicle wirelessly. Mojo Mobility is known for developing highly efficient wireless charging systems capable of transferring high power without need for precise alignment between the charger and the vehicle.
Wireless charging technology has the potential to significantly enhance the convenience of electric vehicles – and thereby increase the appeal and acceptance among consumers – while possibly enabling smaller battery pack sizes and reduced vehicle weight. HATCI and Mojo Mobility will develop, implement and demonstrate a wireless power transfer system on a test fleet of Kia Soul EVs over three phases, at HATCI in Superior Twp., Michigan, and Mojo Mobility in Santa Clara, California.
During Phase One, the partnership developed a wireless power transfer system that has more than 85 percent grid-to-vehicle efficiency and is capable of transferring in excess of 10 kW to the vehicle for fast charging. The new system will allow misalignment between the energy transmitter on the ground and the energy receiver on the vehicle, making it easier and more convenient for day-to-day usage. In Phase Two, the partnership collaborated to integrate a compact system optimized for the Soul EV and demonstrate full operation at a record 92 percent efficiency. Real-world performance data will be gathered in the third and final phase of the project using five Kia Soul EVs and corresponding energy transmission units. This final phase will test the systems’ durability, interoperability, safety, and performance.
