A milestone has been reached in the long effort to establish a single charging standard for electric vehicles. After 18 months of testing and deliberations, a Society of Automotive Engineers (SAE) task force has adopted a charge coupler design based on butt-type contact technology. The design thus becomes part of the J1772 standard of SAE. The action sets the stage for marketplace competition in inductive charging systems. The task force also considered pin and sleeve technology, which the Japan Electric Vehicle Assn. adopted as the standard in Japan. SAE J1772 will continue to reference this standard.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
