Volkswagen ID.4, Nissan Ariya bring EV drive to compact crossovers … chasing Tesla Model Y

Can new electric entries in a hugely popular segment convince U.S. buyers to buy EVs from Nissan and VW as family vehicles? Two new battery-electric models from major global car brands are about to bring electric cars into a category where they’ve been notably absent: family crossover utility vehicles. The 2021 Volkswagen ID.4 and 2022… Read more »

The technical challenges of bidirectional chargers

For years, we’ve been hearing about an EV technology that promises to be a game-changers: Vehicle-to-Grid (V2G) bidirectional charging. My recent work with one V2G charger developer, Fermata Energy, has convinced me that V2G has found its proverbial killer app: load peak shaving for commercial/industrial energy customers. This article is going to concentrate on the… Read more »

Li-Cycle recovers usable battery-grade materials from shredded Li-ion batteries

Q&A with CEO Ajay Kochhar It’s usually one of the first objections cited by EV naysayers: batteries can’t or won’t be recycled, and they contain hazardous materials that will end up in landfills. In fact, no such sinister scenario is likely—most of the components of Li-ion batteries are valuable, and it’s quite feasible, technically and economically,… Read more »

Turnkey transit bus electrification: Enel X offers full service EV-fleet installations for city and school buses

Q&A with Giovanni Bertolino, Head of E-Mobility at Enel X Some of the most compelling stories in the EV world these days have to do with charging. For an individual EV driver, charging may seem like a simple matter—plug in your car in the evening, and it’s ready to drive in the morning—and that’s part of the appeal of… Read more »

Shoppers buy more EVs if they understand charging—and now there’s proof (exclusive first look)

New-car salespeople have simple motivations: They want to spend the least time selling you a new car for the highest possible commission. You buy a new car every five years or so; they sell up to 25 cars a month. They make money on the difference in knowledge. That makes electric cars a problem: they… Read more »

Scale up micro-solid-state batteries to large EV cells? It’s not so simple.

Q&A with Ilika Technologies Every other scientist in the battery world seems to be working on commercializing large-scale solid-state batteries for use in EVs. The potential for technical and safety benefits is substantial, so there will be a big pot of gold for those who first make real advancements on the automotive level.  Using solid… Read more »

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 »
