Specialized motor materials and constructions (Part 2)

The previous article in this two-part series looked at specialized materials that are (or will be) used in motors; the focus this time will be on the innovative methods of construction that make motors more suitable for EV traction applications. Separating the wheat from the chaff is especially important here, because hyperbole (and outright fantasy)… Read more »

Model Y: Tesla’s latest model is its most refined—and it continues to improve

Every Tesla model has arguably been a historic vehicle. The Roadster was the first EV to offer the performance and aesthetics that attract car buyers. Model S was the first mass-produced EV to deliver this combination, and Model X delivered it as an SUV. Model 3, the culmination of the company’s master plan, was the… Read more »

How to ensure EV traction motor magnets aren’t pushed beyond their operating limits

Avoiding motor demagnetization: John Wanjiku, Technical Specialist at Mentor Graphics, explains the goals of a detailed traction motor design analysis. Neodymium permanent magnets are used in EV traction motors because of their powerful magnetic fields and relatively strong resistance to demagnetization, but they tend to lose their magnetism when exposed to excessive operating temperatures, opposing… Read more »

The emerging “non-utilities”—EVs are helping new players in the energy marketplace.

Gordon Feller serves on the boards of several non-profit organizations focused on the future of greener mobility. He formerly served as President Obama’s appointee to a US Federal Commission established to assess emerging energy-focused digital technologies. Dramatic pricing changes, shifting cost structures, new demand curves and technologies that enable efficient decentralization are driving a dramatic… Read more »

The sun-to-car connection: SolarEdge provides the missing link from solar panels to EV charging

Q&A with SolarEdge Founder and VP of Marketing and Product Strategy Lior Handelsman  An EV is a fine thing on its own—but it becomes truly transformative as part of a local system that also includes solar panels, battery storage and smart charging. SolarEdge Technologies provides hardware and software to bring these elements together, including solar… Read more »

COVID-19 vs EVs: What happens?

EVs may experience minor hiccups, but they shouldn’t suffer much more than the rest of the auto industry. It’s the question everyone has to ask: How will the Covid-19 pandemic affect my business? For those in the electric-car world, the question is more pointed: Will the pandemic hurt the growth of electric vehicles over the… Read more »

Seven future electric pickup trucks. Maybe.

Over the first 10 years of their existence, most modern battery-electric cars have been compact hatchbacks or Teslas. While a few are marketed as crossover utility vehicles, none have been the full-size pickup trucks that make up a huge and very profitable segment of US vehicle sales. That’s about to change. What follows is a… Read more »

Specialized motor materials and constructions (Part 1)

When demand drives innovation, the state of the art can progress quite rapidly, but if the demand is not there yet, the end result is often the proverbial “solution in search of a problem.” One of the most prominent examples of this is the lithium-ion battery, which was developed in the 1970s, but didn’t really… Read more »

In-Charge Energy is preparing for the coming tsunami of commercial electric trucks

Widespread adoption of electric commercial vehicles has seemed to be just around the corner for several years now. This has been a puzzling and frustrating situation for EV advocates (and even more so for electric truck builders), because the economic case for electrification is strong. Several industry experts have told Charged that the slow progress… Read more »

EnergyHub gives utilities more flexibility to manage peaks, including direct control of EV charging

The electrification of transport is proceeding in parallel with a major restructuring of the electrical grid, and these trends interact with each other in several ways. As the grid transforms from a centralized model to a decentralized model, utilities are facing an entirely different set of technical challenges than those that existed a century ago,… Read more »
