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 »

Seaworthy EVs: Leclanché designs and manufactures Li-ion cells and systems

The advantages of electrifying transportation are far-reaching. Advanced energy storage systems are even making their way into the commercial marine industry. There are many marine applications in which adding a large Li-ion battery pack makes a lot of sense. The best-use case varies depending on the boat size and purpose. All-electric ferries, for example, are… Read more »

Turnkey drivetrains: UQM, Eaton and Pi Innovo collaborate to help build better heavy-duty EVs

We write about electric buses a lot at Charged. That’s because, as our July/August cover story pointed out, we think that e-buses will inevitably become the top choice for cities and municipalities. This could happen a lot quicker than many people realize, and some have predicted that transit buses will be the first segment in… Read more »

ITT Cannon introduces new fast charging hardware to the next generation of EVs

The future of the EV industry is bright. We’re losing count of all the planned EVs that automakers have in the pipeline. And it seems increasingly likely that they will follow through with those plans. If there’s one thing everyone agrees on, it’s that all EVs in the near future will have a range of… Read more »

LORD Corporation builds on its work potting electric motors, reducing hot spots by up to 40%

In 2013, Shafigh Nategh completed his doctoral thesis on the thermal management of high-performance electrical machines at the KTH Royal Institute of Technology in Stockholm, Sweden, and by 2014, the results of his doctoral work had begun to pique the interest of some heavy hitters in the electric motor industry. For his thesis, Nategh designed… Read more »

BMW electrifies its best-selling model: the 330e iPerformance PHEV launches in the US

Which major automaker has sold the highest percentage of plug-in vehicles relative to its overall US sales? You may be surprised to learn that it’s BMW – aside from Tesla, of course, which sells 100% EVs. In the first half of 2016, BMW’s four plug-in vehicles – the i3, i8, X5 xDrive40e and 330e iPerformance… Read more »

The inevitability of electric buses

Electric transit buses enter the fast-follower market stage as the leaders work to remove the last barriers to adoption. Q&A with Proterra’s Ryan Popple and ABB’s Daan Nap on the state of the market and charging standards in North America and Europe. With each passing year, more decision makers are realizing that city buses are an… Read more »

Researchers use nanolithia to improve efficiency and longevity of lithium-air batteries

Lithium-air, or lithium-oxygen, has been touted as the ultimate battery technology, because its theoretical energy density is ten times that of current lithium-ion solutions. However, scientists have struggled to overcome major challenges with the technology. The batteries waste a lot of energy as heat, degrade relatively quickly, and often require extra components to pump oxygen… Read more »

Improving aerodynamic modeling: Combining airflow dynamics with vehicle-handling models

Tuning a vehicle’s aerodynamic features is nothing new. Engineers have been using wind tunnels for decades, and more recently they’ve also employed computational fluid dynamics (CFD) software to reduce drag, minimize noise and increase stability by preventing undesired lift forces. In the expanding world of EVs, car builders are doubling down on efforts to push… Read more »
