LORD is developing a rotary band brake aimed at automotive thermal management systems

“Any product that uses less power and has high torque in a small package could be of interest to the EV space,” LORD’s Edward Conner told Charged. We were discussing the company’s electromagnetically actuated rotary band brake technology, and we naturally asked a lot of questions about its potential applications for EVs. The core of… Read more »

Carpenter Technology develops a new soft magnetic alloy with key benefits for EV motors

Electrical steels are soft magnetic materials found at the heart of electric motors. They’re typically manufactured in cold-rolled strips, cut into shapes to make laminations and then stacked together to form the stator and rotor of a motor. These specialty steels are tailored to produce certain magnetic properties, and have a magnetic flux density (key… Read more »

Hyundai launches Ioniq with three distinct powertrain choices: EV, PHEV and hybrid

In the short history of the modern EV industry, it’s been common for automakers to launch plug-in cars under a new brand or model – particularly those companies who are serious about selling EVs at scale. Or, at least the ones that want to appear serious about selling a lot of EVs. Even though Hyundai… Read more »

Tesla’s chief motor engineer discusses the potential of next-generation motor technologies

Tesla spends a considerable amount of resources on basic research into EV systems – as well it should. EV technology is very young compared to that of ICE vehicles, so it’s safe to assume that, in a few short years, the aggregate of many incremental technology advances could lead to significantly better EVs. Of course,… Read more »

Southwest Research Institute consortium conducts independent battery benchmarking

Comparing the spec sheets from different parts manufacturers is tricky business for engineers in any industry. However, the advanced battery market seems to be uniquely challenged in this regard. As Tesla CEO Elon Musk often points out, when it comes to batteries, the BS factor is outrageous. Even if you assume that every vendor provides… Read more »

2017 Chevrolet Bolt EV: The era of long-range, mid-priced EVs is here

The 2017 Chevrolet Bolt EV will surely be remembered as a milestone model in automotive history – and hopefully for more than just the hype that heralded it. For several years, the punditocracy has been saying that the “killer app” that would bring electromobility to a “tipping point” and build that all-important “critical mass” would… Read more »

Wolfspeed launches a new silicon carbide MOSFET for EV inverters

Wide Bandgap (WBG) semiconductor technologies have attracted a lot of attention and research funding in the past decade. Both public and private institutions around the world have been obsessed with accelerating the evolution of WBG tech into commercial power electronics applications. What’s all the fuss about? WBG materials such as silicon carbide (SiC) and gallium… Read more »

Navigant Research analyzes how transition to shared vehicles will effect energy markets

By Scott Shepard, Senior Research Analyst at Navigant Research’s Transportation Efficiencies program Smartphones have really changed the way things get done, and the continuous and sometimes overwhelming revolutions enabled by our hand-held devices are only just beginning. The transformations still to come include the basic process by which people and things are moved. The addition… Read more »

Many of the best-selling EV charging stations on Amazon are not safety-tested and certified

  Most major retailers require that electrical products sold in their stores undergo third-party independent safety testing and certification, Amazon does not. After Charged encouraged the company to change its policy for EV charging stations, an Amazon spokesperson provided this official comment, “We monitor the products sold on our website for product safety concerns, and when appropriate, we… Read more »

California’s big three utilities submit proposals to increase access to EV infrastructure

January 20 was an important day for transportation electrification in California. That was the deadline for the state’s three major investor-owned utilities (IOUs) to submit applications for major upgrades to electric transportation infrastructure. California’s Senate Bill 350 (2015) requires the IOUs to establish programs that will increase “access to the use of electricity as a… Read more »
