Wireless charging systems need to operate at high frequency, at or near resonance, to maximize power transfer distance and efficiency. High voltages appear across the inductors and capacitors. The use of discrete components reduces efficiency, increases system complexity.
This technology aims to provide and integrated and oxidation resistant cladding or coating onto carbon-based composites in seconds.
Electric vehicle drive fluids must have a high dielectric constant to avoid current leakage or even short circuits. On the other hand, lubricants should possess sufficient conductivity to allow static electricity to be released.
Ionic liquids comprising quaternary ammonium and phosphonium cations have been developed as eco-friendly lubricant additives. These additives are tailored for use in environmentally acceptable lubricants (EALs) like polyalkylene glycols, vegetable oils, and synthetic esters.
ORNL has developed a revolutionary system for wirelessly transferring power to electric vehicles and energy storage systems, enabling efficient, contactless charging.
Wireless power transfer technology has been increasingly adopted for charging batteries in various applications, notably in electric vehicles (EVs).
