WiTricity, a leading wireless power solutions company is using its patented magnetic resonance technology to help Chinese automakers in developing wireless electric vehicle (EV) charging as per Chinese national standards(“GuoBiao” or GB standard). The standardization is critical to large-scale deployment of wireless charging for EVs both in China and around the world, allowing any equipped EV to use any standard wireless charger.
WiTricity has been actively involved in the Chinese EV wireless charging standardization process through its work with China Electric Power Research Institute (CEPRI), China Automotive Technology and Research Center (CATARC) and the CEC. With a global IP portfolio of over 1400 issued and pending patents, WiTricity has declared twenty Chinese patents as standards essential to systems implementing the GB standard .
Chinese automakers and their Tier 1 suppliers rely on the GB standard committee to define the EV wireless charging solution to be deployed in China. The ratified standard is now a major market enabler for deployment on vehicles and in public charging infrastructure. WiTricity has worked closely with the GB standard committee on several significant technical matters, including efforts to harmonize the China standard with other international standards (SAE J2954, ISO 19363, IEC 61980) that will be published in 2020 and 2021.
The China automotive market is by far the most aggressive in transitioning to electric, and Chinese automakers are seeking ways to make the EV ownership experience even more appealing to new buyers. Wireless charging makes charging as simple as parking the car and walking away, ensuring that full battery capacity and range is seamlessly available to the driver. Wireless EV charging with WiTricity’s magnetic resonance technology delivers the same power, efficiency and charge rate as conventional plug-in charging methods with no compromises. Wireless EV charging is not just convenient, it is critical for the automatic charging of future fleets of autonomous vehicles, such as robotaxis or delivery vans.
WiTricity plays an active role in working with Tier 1s in China to design and realize systems that will meet China’s GB standard . Zhejiang VIE Science & Technology Co., Ltd. subsidiary (VIE) and Anjie Wireless Technology (Suzhou) Co. Ltd. (Anjie) have licensed WiTricity’s technology and industry-leading designs which include all needed peripheral systems such as foreign object detection, position detection and communications.
These companies develop and commercialize highly efficient EV wireless charging systems for sale to leading automaker brands in the China market. VIE has completed construction of its pilot production facility to assemble wireless charging systems for its initial OEM customers. Anjie recently demonstrated a fully autonomous parking and wireless charging experience on an Xpeng Motors’ EV, showing the world what the future of autonomous, electric mobility will look like in the years to come.
China is regarded as the world’s largest EV market, the global EV trend setter, and a key market for WiTricity. Following their close ties with CEC, CATARC and CEPRI, Witricity confirms that the published GB standard will create a clear path for automakers and their Tier 1 suppliers in China to implement wireless charging.
