SAE updates J2954 wireless charging standards for EVs up to 11 kW
SAE International has published a second version of Recommended Practice (RP) SAE J2954, its standard for wireless power transfer (WPT) for EVs of up to 11 kW power levels. The RP establishes specifications for interoperability, electromagnetic compatibility, EMF, minimum performance, safety, and testing for wireless charging of light-duty electric and plug-in EVs. SAE is seeking… Read more »
SAE releases new J3068 specification for charging of medium- and heavy-duty EVs
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 »
Bob Lutz laments the end of the automotive era
Quintessential car guy Bob Lutz, the father of the Chevy Volt and one-time Tesla admirer turned harsh critic, had some bad news for an audience of engineers at SAE International’s recent annual meeting in Detroit. Once vehicle autonomy reaches its logical conclusion, humans will be reduced to passengers in standardized, soulless automated vehicles. People who… Read more »
What’s the current state of wireless EV charging?
By Lisa Jerram, principal research analyst overseeing Navigant Research’s Transportation Efficiencies program Wireless charging is becoming more mainstream among consumer electronics – witness the proliferation of wireless chargers at CES 2018 – but it is not just for smartphones and fitness bands. Automakers are working in earnest to offer wireless charging options for their… Read more »
SAE J2954 Recommended Practice enables automated wireless charging to 11 kW
SAE International has published a new Recommended Practice (RP), SAE J2954, which provides the first worldwide specification for wireless power transfer (WPT) up to power levels of 11 kW (WPT 3). This follows the organization’s previous Technical Information Report J2954, which dealt with power levels up to 7.7 kW (WPT 2). The new RP also… Read more »
SAE releases global standard for wireless charging
At a recent standards meeting, carmakers, Tier 1 suppliers, and technology providers have reached agreement on key technical and procedural elements of the upcoming SAE Recommended Practice (RP) for Wireless Power Transfer (WPT) and automated parking alignment and charging. The goal of this standardization is to ensure interoperability among different brands of EVs and wireless… Read more »
Researchers complete bench testing to validate SAE wireless charging standard
Researchers from Idaho National Laboratory (INL), along with the DOE and several automotive companies, have completed bench testing to support SAE Technical Information Report (TIR) J2954, a guideline for wireless charging that was published earlier this year. The SAE’s TIR J2954 is designed to ensure the performance and safety of Wireless Power Transfer (WPT) systems,… Read more »
Rich Byczek on delayed battery overheating and stranded energy
(This article originally appeared in Charged Issue 6 – JAN/FEB 2013) EV standards gaps: Intertek’s Rich Byczek on two of the biggest safety concerns centered around batteries. The EV industry is young and evolving quickly – too quickly, in some cases, for the standards community to keep up. The competing charging standards provide the most obvious example. There are… Read more »
SAE publishes recommended practices for emergency personnel in EV crashes
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.
