Researchers at Oak Ridge National Laboratory in Tennessee recently announced that they have set a record for wireless EV charging. Their system’s magnetic coils have reached a 100-kilowatt power level. In tests in their lab, the researchers reported their system’s transmitter supplied enough energy to a receiver mounted on the underside of a Hyundai Kona… Continue reading 50 by 20: Wireless EV Charging Hits Key Benchmark

Hyundai’s Ioniq 5 N Accelerates Performance Tech
Some people will tell you EVs are always more fun-to-drive than internal combustion cars. But performance and racing engineers know that’s not really true. Otherworldly acceleration aside, most EVs suffer from a distinct lack of old-school driving engagement: Numb electric steering, no stirring sounds or gears to shift, and excess weight that dulls handling. Throw… Continue reading Hyundai’s Ioniq 5 N Accelerates Performance Tech
Hydrogen Is Coming to the Rescue
A consortium of U.S. federal agencies has pooled their funds and wide array of expertise to reinvent the emergency vehicle. The hybrid electric box truck they’ve come up with is carbon neutral. And in the aftermath of a natural disaster like a tornado or wildfire, the vehicle, called H2Rescue, can supply electric power and potable… Continue reading Hydrogen Is Coming to the Rescue

E-Bikes Are Growing Up, Finding Jobs, Still Having Fun
Since Tesla seized the world’s imagination, EVs have been cast as lead rebels in the transportation revolution. Then e-bikes whirred into the war against climate change. In 2024, a maturing industry is broadening its design ambitions and engineering sophistication. Manufacturers are expanding into traditional riding categories and creating new ones: Fat-tire bikes and lightweight commuters.… Continue reading E-Bikes Are Growing Up, Finding Jobs, Still Having Fun
Unico’s Battery Testing Enters a Competitive Industry
As EV production and, with it, battery production accelerate over the next decade, so too will the demand for rigorous EV battery testing. But producing a battery that will stand up to the task of powering an electric vehicle for years under different weather conditions and unpredictable usage patterns is no mean feat. Battery manufacturers… Continue reading Unico’s Battery Testing Enters a Competitive Industry
AI Takes On India’s Most Congested City
In just 30 years, the South Indian city of Bengaluru has gone from a sleepy retirement town to the capital of the country’s burgeoning technology sector. But such rapid development has left it with some of the most congested roads in the world. Now, a former chip engineer has been drafted in to act as… Continue reading AI Takes On India’s Most Congested City
