In Issue 49, we reviewed some of the more promising advancements in materials and construction techniques for EV traction motors, one of which—the axial flux design—will be the focus of this article. Despite being characterized as an advanced construction technique, the axial flux design is actually one of the oldest ways of constructing a motor—it’s… Read more »

2022 Chevrolet Bolt EUV: Chevy’s lowest-priced electric car gets a big brother
US drivers see the Bolt EUV as a larger, better-equipped version of Chevy’s first modern electric car. But the EUV first went into production last year in China—as a Buick. If it were a person, you might almost feel sorry for the 2022 Chevrolet Bolt EUV, which was launched in February. It’s a brand-new vehicle,… Read more »
Former EPA exec surveys the road ahead for US emissions standards
Q&A with former EPA exec Margo Oge Federal emissions and fuel economy regulations have been instrumental in encouraging (or coercing) automakers to produce EVs, and to make their legacy vehicles cleaner. Since President Nixon signed the Clean Air Act in 1963, federal regulations aimed at reducing air pollution have gradually grown stronger. Under President Obama,… Read more »
Wildcat ramps up its focus on EV Supercell breakthroughs
The lithium-ion battery has proven to be an excellent fuel tank for EVs, but there remains much room for improvement. We’re still far from what’s theoretically achievable in terms of Li-ion capacity, safety, cost and charge times. As battery manufacturers continue their quest for improved chemistry and material combinations, they rely on applied researchers like… Read more »
Knowles develops next-generation safety capacitors to meet the growing demand for 800-volt EV systems
As EV-makers continue to upgrade from 400 V to 800 V systems, parts suppliers have been hustling to keep up with the new specs. Knowles Precision Devices, for example, specializes in high-voltage capacitors—it’s a market leader in multi-layer ceramic capacitors rated from about 200 V up to 12,000 V. Looking back just 10 or 15… Read more »
Extreme E tackles tough terrain, promotes sustainable racing
Formula E, the FIA-sanctioned electric racing series, has been a powerful ambassador for the EV revolution—and a damn fine sporting event—since its opening season in 2014. Now some of the same team behind Formula E, including Alejandro Agag, Chairman of Formula E and now CEO of Extreme E, have gone off-road and off the chain… Read more »
Is Ford planning an electric version of the Bronco?
Ford seems to be following a sound strategy of electrifying models in the segments most popular with buyers (rather than those that seem convenient to electrify). The Blue Oval has a hit on its hands (if it wants one) with the Mustang Mach-E, and it could make history with the upcoming F-150 Lightning. The Bronco… Read more »
Which US states have the highest penetration of EV charging stations?
Expanded access to charging infrastructure is seen as one of the keys to accelerating EV adoption, and the US is rapidly rolling out public charging stations. A new report from the DOE tells us that 25 states now have at least 1,000 non-residential charging units (public and private). California has by far the most: nearly… Read more »
Swiss car-sharing firm to install hundreds of charging stations
Swiss car-sharing provider Mobility operates a fleet of some 3,000 vehicles, many stationed at Switzerland’s ubiquitous train stations to provide last-mile transportation. The company’s first foray into electrification was a bit too early—it began offering EVs in 2011, but later took most of them out of service. Now the value proposition for EVs has improved,… Read more »
New paper shows atomic-scale closeups of how a lithium-metal electrode ages
Lithium-metal batteries, which use anodes made of lithium metal rather than graphite, could offer great improvements in energy density and weight. The DOE’s Battery 500 Consortium has set a goal of developing lithium-metal EV batteries with triple the energy density of today’s Li-ion cells. Now scientists at Stanford University and the SLAC National Accelerator Laboratory… Read more »
