VW develops EV wireless charging, shows range-boosting materials research


    Volkswagen on Tuesday confirmed that it’s engaged on wi-fi charging—in its personal patented coil and charging pad design, with silicon-carbide supplies, aimed partly towards every day storage use. 

    The challenge goes properly past that, although—into cost charges which are at the moment on the speedy facet of DC fast-charging territory. 

    Based on Volkswagen, their unique try was within the type an early 6.6-kw prototype, which might carry out at cost charges similar to dwelling Degree 2 (240-volt) methods. However in early trials along side a silicon carbide inverter, the system has carried out as much as 120 kw with a prototype. Additional VW has a future aim of upping the system to 300 kw.

    To date, wi-fi charging has largely been within the type of purposes meant for dwelling use. There are just a few high-power methods in use or growth, and most of them are focused towards use on bigger industrial autos. One exception is a wi-fi charging taxi take a look at in Norway from Momentum Dynamics (InductEV). 

    The U.S. growth of this Volkswagen system is being carried out at VW’s Knoxville Innovation Hub, along side Oak Ridge Nationwide Lab (ORNL) and the College of Tennessee (UT), benefiting from the 2 tutorial establishments’ experience with high-power wi-fi charging and power-electronics optimization, respectively. 

    Along with the tease of future hands-free charging tech for its autos, VW boasted that with supplies work being carried out along side UT, leading to a 3D-printed resin-based construction, it might be able to create a body for the battery pack that cuts weight by 60%—with sturdiness and vitality absorption past that of metal. That would assist increase driving vary in future EVs.

    VW additionally confirmed the potential for utilizing paper-based merchandise (hot-pressed cellulose fiber bolstered thermoplastics) to exchange plastics in some car areas. Additional, it revealed U.S.-based analysis with light-weight supplies that is likely to be put to make use of in “pickup beds and rugged parts” for future merchandise. In a course of referred to as “sizing,” it’s working to optimize the fiber-matrix-interface in sheet molding compound (SMC) processes for higher sturdiness. It kicked off that challenge by producing a light-weight model of a VW Atlas liftgate that saved 13 kilos (35%) versus steel.

    This type of devoted design method to weight financial savings is arguably associated to the AI-based generative design method that VW has dabbled with in U.S.-based ideas and analysis within the latest previous—together with its Sort 20 Microbus Idea that the corporate’s U.S. arm developed whereas the ID.Buzz electrical van was taking type in Germany.
