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.
