California environmental lawyer forecasts the future of state and federal emissions regulations

Q&A with environmental lawyer Maureen Gorsen California has led the nation in the fight against air pollution. The state has consistently implemented clean-air rules that are stricter than those imposed at the federal level, including the zero-emission vehicle (ZEV) mandate, which requires automakers to produce a certain number of electric vehicles. The Trump administration attempted… Read more »

A closer look at axial flux motors

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 »

BoostEV is an on-demand mobile EV charging network, like UberEats for hungry EVs

The EV ecosystem is a work in progress, and when it comes to charging infrastructure, there are some key pieces missing from the puzzle. There will surely be a need for some form of portable charging on demand, and this is the niche that SparkCharge is looking to fill with its new app platform, BoostEV…. Read more »

High-voltage EV battery packs: benefits and challenges. More voltage, more better?

In 2020, Porsche delivered just over 20,000 units of its luxury Taycan EV—the first vehicle from a major automaker to sport an 800 V (nominal) battery, which is more than double the voltage of its competitors (and firmly into light-rail and switchyard locomotive territory, actually). It appears that many other EVs will soon follow in… Read more »
