SAE International’s Wireless Power Transfer and Alignment Task Force is urging the US Federal Communications Commission (FCC) to act to support the commercialization of wireless charging operating in the frequency band of 79 kHz to 90 kHz. The SAE task force consists of more than 150 international experts representing automakers, suppliers, users, national laboratories and… Read more »
SAE International has announced revisions to SAE J3072 Standard: Interconnection Requirements for Onboard, Utility-Interactive Inverter Systems and SAE J2847/3 Recommended Practice: Communication for Plug-in Vehicles as a Distributed Energy Source. The updated EV charging documents will play a role in advancing automotive requirements for distributed energy resources (DER) projects. The revisions to SAE J3072 establish… Read more »
SAE International has announced an agreement with a contractor team, comprised of Eonti, DigiCert and VerSprite, to perform technical development of the SAE EV Charging Public Key Infrastructure (PKI) project, an industry-led research project aimed at strengthening EV charging system security. The PKI project was launched in May 2020. With the contractor team onboard, technical… Read more »
SAE International has published a new global standard that specifies both the vehicle-side and charger-side requirements for wireless charging of EVs. The new standard, SAE J2954, was more than a decade in the making. In 2007, when SAE began its research, there were few EVs on the market, and wireless power transfer (WPT) may have… Read more »
As the EV market expands, there’s a pressing need for more standardization of DC power distribution, especially for buses and heavy-duty vehicles. SAE International’s new standard SAE J-3105: Electric Vehicle Power Transfer System Using Conductive Automated Connection Devices Recommended Practice promotes the safe testing and performance of mechanized conductive power transfer systems, primarily for vehicles… Read more »
SAE International has published its recommended practice for plug-in charging of heavy-duty EVs. The new J3068 standard allows vehicles to fully utilize three-phase AC power. Presenting a symmetric three-phase load enhances grid stability, especially at high power levels. SAE J3068 standardizes an AC three-phase-capable charging coupler and digital control protocols, offering sufficient power and reliability… Read more »
SAE International has released an official technical standard called “J2990-Hybrid and EV First and Second Responder Recommended Practice,” that lists best practices for responders.
