Nth Cycle says its electroextraction tech significantly reduces transportation costs for Li-ion battery recycling

Refining the circular economy for battery materials. As the e-mobility transition accelerates, demand for critical minerals is growing exponentially. Companies on the cutting edge, such as Tesla, are already experiencing shortages. However, to extract ever more minerals by mining and dispose of the waste in landfills, would be to continue the practices that got the… Read more »

TeraWatt Infrastructure aims to address the massive energy capacity needs of EV fleet charging depots

As more fleets of medium- and heavy-duty vehicles go electric, there’s a growing awareness that building the necessary charging infrastructure will be a complex proposition, requiring specialized expertise and considerable capital. Fleet vehicle depots will need to incorporate not only charging stations, but energy management systems, and possibly energy storage and on-site generation. These sites… Read more »

A closer look at why heat pumps are dominating EV HVAC systems

Heating or cooling the interior cabin of an EV substantially affects the vehicle’s on-road efficiency, and the HVAC system often gets the proverbial “rented mule” treatment. In an ICE vehicle—particularly an underpowered one—there is a visceral reminder that running the AC, at least, costs something, since there is a palpable hit to acceleration whenever the… Read more »

2021 Jeep Wrangler 4xe: The legendary SUV brand’s first plug-in hybrid

The plug-in hybrid version of the Jeep Wrangler offers useful all-electric range and great electric torque—if drivers plug it in. Do they? The accelerating pace of electric vehicle launches has brought us to this: The first Jeep in the US to get a plug-in hybrid version is the legendary Wrangler. In Europe, it was smaller… Read more »

ABB charges into the future with Formula E

The global electric racing championship Formula E has been a huge success by any measure. Automakers like Mercedes-Benz, Porsche, Nissan, and Jaguar have embraced the series, which is surely the world’s most prominent showcase for electric vehicle performance. Charged attended the New York City E-Prix in July, and spoke with several execs from EV infrastructure… Read more »

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 »
