Magnetic resonance has emerged as the leading technology for wireless power transfer over distance, and as the technology evolves, companies looking to take solutions to market will rely on standards to streamline development, reduce costs, and accelerate adoption. A number of organizations are developing specifications, and as a holder of the foundational patents for highly resonant wireless power transfer over distance, these standards efforts will rely on WiTricity technology as part of the backbone for the technical specifications.
As part of our efforts to increase market adoption and time-to-market for our customers, WiTricity is an active member of the following organizations:
WiTricity has been involved as a leader in the development of SAE work-in-progress (WIP) J2954 for wireless charging of EVs and PHEVs, and has been the chair of several of the working groups associated with J2954. The J2954 group members include most of the major automakers and Tier 1 suppliers.
SAE International is a global association committed to being the ultimate knowledge source for the engineering profession. By uniting over 127,000 engineers and technical experts, we drive knowledge and expertise across a broad spectrum of industries. We act on two priorities: encouraging a lifetime of learning for mobility engineering professionals and setting the standards for industry engineering.
International Organization for Standardization
ISO is an independent, non-governmental international organization with a membership of 163 national standards bodies. Through its members, it brings together experts to share knowledge and develop voluntary, consensus-based, market relevant International Standards that support innovation and provide solutions to global challenges.
China GB standards for Wireless Charging of Electric Vehicles
The Standardization Administration of the People’s Republic of China (SAC) has ratified and published the first four national China recommended standards for wireless charging of electric vehicles. These standards were developed within the Wireless Charging Standards Working Group for Electric Vehicles administered by the China Electricity Council (CEC), the China Automotive Technology and Research Center (CATARC), and the China Electric Power Research Institute (CEPRI). These China GB Standards are the first to be ratified and published amongst global standards organizations. The standard is planned to become effective within 2020.
These four national standards provide a framework for car makers, Tier 1 suppliers, and infrastructure suppliers to develop and commercialize wireless charging systems that meet guidelines for safety, performance, and interoperability. The standards specify the requirements related to power transfer and system control and communications that should be followed in product design and test of electric vehicle wireless charging systems. It gives clear baseline requirements for power delivery levels and efficiency, and safety sub-systems. It clarifies the necessary testing methods to ensure compliance with the standards and provides clear guidance and recommendations for product design and testing. The standard for communications protocol defines the process, parameters and data definition for Wi-Fi communications between the vehicle and the ground side wireless charging system and specifies the minimum communication protocol architecture of the ground side system. The standards provide clear direction for exposure limits on electromagnetic environment for human safety, and for testing methods and evaluation protocols to ensure compliance.
