SAE International, in collaboration with Intel, has established a new committee to advance the energy efficiency of EVs. The Vehicle Platform Power Management Committee (J3311), which is chaired by Intel, aims to use power management principles from the PC industry to make all EVs more energy-efficient and sustainable. This new committee will establish a Vehicle… Read more »

SAE International lays foundation to implement Tesla’s NACS connector standard
Charging providers and automakers have rushed to adopt Tesla’s North American Charging Standard (NACS), which features a simpler and more compact connector than the brand-neutral CCS. In fact, the enthusiasm for NACS has been so great that the market has outrun the standards-adoption process. SAE International has now taken a major step towards bridging that… Read more »
SAE International announces alignment methodology for wireless EV charging standard
SAE International’s Wireless Power Transfer & Alignment Taskforce has been working on a new wireless EV charging standard for some time. Now, following a “lengthy consensus process,” the group has decided upon Differential Inductive Positioning System (DIPS) as the technology alignment methodology for the SAE J2954 standard, Wireless Power Transfer (WPT) for Light-Duty Plug-in/Electric Vehicles… Read more »
SAE International updates standard for bidirectional EV/charger communication
The SAE International Hybrid Communication and Interoperability Task Force has completed an extensive revision of SAE Standard J2847/2: Communication Between Plug-in Vehicles and Off-Board DC Chargers. This update is the first step towards the goal of enabling EV and charging station providers to use the same communication code for bidirectional DC charging, including Vehicle-to-Grid (V2G)… Read more »
SAE International launches certification for EV charger repair technicians
Anyone who regularly uses, or attempts to use, public EV chargers will surely agree that there’s a pressing need for EVSE repair technicians. Standards body SAE International has produced a certification program to verify skills and knowledge of technicians who maintain, repair and operate EV charging stations. The SAE Electric Vehicle Supply Equipment (EVSE) Technician… Read more »
SAE International announces standardization process for Tesla’s NACS connector
As the US EV industry rushes to embrace Tesla’s charging system, one of the criticisms that we’ve heard is that, whatever Tesla may say, NACS isn’t truly a standard. Now standards body SAE International has taken a step towards alleviating that problem, announcing that it will standardize the NACS connector in order to ensure that… Read more »
SAE International launches initiatives centered on EV charging station reliability
The abysmal dependability of public chargers is a major problem, and fixing it is going to require some serious technical expertise and industry-wide cooperation. So it’s encouraging to see industry heavyweight SAE International, which calls itself “the oldest and largest technical society for engineers in the US, and the largest mobility standards organization in the… Read more »
Electrify America to add Tesla’s NACS connector to its EV charging stations by 2025
The writing is on the wall, and public charging networks are making plans to add Tesla’s NACS connector to its EV charging stations (or to add more). Electrify America/Electrify Canada, which operates some 850 stations with about 4,000 individual chargers, appears to be taking a more cautious approach than some. The company says it will… Read more »
ENRX to test dynamic wireless EV charging on Florida highway
Dynamic wireless charging would seem to be the ultimate in convenience—you don’t have to wait, you don’t even have to stop, just charge away as you roll down the highway. Reasonable minds may differ as to what use cases would justify the complexity and cost of such a system, but it’s certainly worth researching, and… Read more »
Developing standards for EV charging reliability
Q&A with Frank Menchaca, President of SAE International’s Sustainable Mobility Solutions The reliability—or rather, the unreliability—of public EV charging stations is nothing less than a scandal, and it’s holding back EV adoption. This tragedy involves a cast of many players—automakers, charger manufacturers, network operators, electric utilities, and often a lot more—and all need to start… Read more »
