UL certifies WAVE’s 50 kW wireless charging system

Wireless Advanced Vehicle Electrification (WAVE) makes a wireless charging system that provides in-route charging for transit buses, using a pad embedded directly into the roadway (see the March/April 2016 issue of Charged). Now the company has earned a Field Evaluation Certification from Underwriters Laboratories (UL) for a 50 kW system that it has deployed for… Read more »

SAE releases global standard for wireless charging

At a recent standards meeting, carmakers, Tier 1 suppliers, and technology providers have reached agreement on key technical and procedural elements of the upcoming SAE Recommended Practice (RP) for Wireless Power Transfer (WPT) and automated parking alignment and charging. The goal of this standardization is to ensure interoperability among different brands of EVs and wireless… Read more »

Researchers complete bench testing to validate SAE wireless charging standard

Researchers from Idaho National Laboratory (INL), along with the DOE and several automotive companies, have completed bench testing to support SAE Technical Information Report (TIR) J2954, a guideline for wireless charging that was published earlier this year. The SAE’s TIR J2954 is designed to ensure the performance and safety of Wireless Power Transfer (WPT) systems,… Read more »

SAE issues guideline for wireless charging standard

Wireless charging certainly seems like the future, but the lack of technical standards has stalled the release of systems from the major EV makers. Now SAE has published an industry guideline for wireless power transfer (WPT) between infrastructure, vehicle suppliers and OEMs. “SAE TIR J2954 Wireless Power Transfer for Light-Duty Plug-In/ Electric Vehicles and Alignment… Read more »
