- Dr. Steve Mitchell presented on investigating the viability of wireless charging technology for electric mining vehicles. - Wireless charging could allow mining vehicles to charge dynamically while working, eliminating the need for battery changes, trailing cables, or connector brushes. This would improve efficiency and reduce emissions from diesel vehicles. - The technology uses magnetic resonant coupling between transmitting and receiving coils, similar to a transformer. Advances have achieved over 80% efficiency with a 20cm air gap, allowing power transfers sufficient for loader vehicles.
