WAVE demonstrates 250 kW wireless en route charging for e-buses

WAVE (Wireless Advanced Vehicle Electrification) has demonstrated a 250 kW Wireless Power Transfer System prototype. The company will deliver the new charging system to the Antelope Valley Transit Authority (AVTA) in California later this year. WAVE’s technology transfers power from a charging pad embedded in the pavement to a receiving pad mounted on the vehicle’s… Read more »

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 »

WAVE wireless charging helps transit agencies save money by going electric

Wireless charging technology is almost ready for the big stage. Qualcomm has demonstrated its Halo system in various vehicles, including the Drayson B12/69 electric race car. Evatran’s Plugless aftermarket system is now commercially available for the Volt and the LEAF, and a Model S-compatible version is coming soon. Several major automakers have indicated that they’re… Read more »

Highways England to conduct off-road trials of dynamic wireless charging

Highways England, the government-owned company that manages England’s road network, plans to conduct off-road trials of a system that can charge EVs as they roll down the motorway. The trials follow a feasibility study into ‘dynamic wireless power transfer’ technologies, completed by TRL and Halcrow. “The potential to recharge low-emission vehicles on the move offers exciting possibilities,”… Read more »

Researchers find a way to double transfer efficiency of wireless charging

Researchers from North Carolina State University and Carnegie Mellon University have found that adding a magnetic resonance field enhancer (MRFE) – which can be as simple as a copper loop – to a wireless charging system can boost transfer efficiency by at least 100 percent, and possibly as much as 5,000 percent. “Our experimental results… Read more »
