AMPLY Power offers EV fleets guaranteed uptime and zero charging challenges

AMPLY Power says its charging as a service model provides 99.9% uptime, critical to scaling EV deployments Fleet charging management may not be the most glamorous segment of the EV industry, but it is emerging as an extremely important component of the future EV ecosystem. As commercial fleets electrify, they are finding that they need… Read more »

2022 Hyundai Ioniq 5: First of an aggressive wave of new EVs

The 2022 Hyundai Ioniq 5 should be taken very seriously when it goes on sale this fall. It will be a new and likely very competitive entry in what will soon become a crowded field of EVs in the popular “compact crossover” segment.  It’s not the first such EV: the Ford Mustang Mach-E, Tesla Model… Read more »

A closer look at humidity control methods for EV electronics

It’s a well-known trope that water and electricity don’t mix, but keeping the two separated is often deceptively difficult, because the simple solution of just sealing the box is insufficient on its own. This is because of condensation, which can come from water vapor in the air at the time the box was sealed, or… Read more »

HBK’s digital algorithm can map EV motor efficiency 10 times faster than analog systems

In order to maximize an EV’s range for a given battery capacity and vehicle weight, engineers try to eke out as much performance as possible from the electrical and mechanical systems. Using a process called efficiency mapping, they determine the “sweet spots” of a powertrain—the regions of the torque-speed curve where the system operates at… Read more »

Study: Four of five new-car buyers can charge EVs at home

A recent survey of new-car buyers suggests 4 of 5 will be able to charge an EV at home—making it even more critical that they understand how charging is actually done. If projections from major carmakers are to be believed, the bulk of electric cars that will travel on US roads in 2026 haven’t been… Read more »

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 »
