Simplifying EV traction inverters emergency power supply architecture

The low voltage power architecture used in EV traction inverters drives control electronics and provides gate driver power for the main traction IGBTs/MOSFETs. It must also provide redundancy to meet ASIL requirements. This requirement represents a special challenge as it means the Emergency Power Supply (EPS) must operate from low voltage and high voltage sources… Read more »

Chevrolet’s electric Silverado pickup to debut at CES 2022

Electric pickups are expected to be the next big thing, and newcomer Rivian stole a march on everyone—Ford’s F-150 Lightning is in pre-production, but deliveries aren’t to start until spring of 2022. Tesla’s Cybertruck is delayed until who-knows-when. GM may be struggling to catch up, but it’s moving forward. The latest news is that Chevrolet’s… Read more »

Road test indicates existing electric trucks could replace millions of diesels on short-haul routes

When it comes to long-haul trucking, battery-electric trucks face a number of challenges, including weight restrictions and the need for an ultra-high-power charging solution. However, despite what you may read in those “anything but EVs” articles, the jury’s still out on when, or whether, battery and charging specs will improve to meet these challenges, or… Read more »

Lyten introduces lithium-sulfur battery platform

Material supplier Lyten has introduced its new LytCell lithium-sulfur (Li-S) battery platform. The new platform was developed specifically for the EV market, and is designed to deliver three times the specific energy of lithium-ion batteries. Lyten has previously worked with the US government to test LytCell in defense-related applications, and is now ready to introduce… Read more »

Volkswagen’s ID.4 electric crossover has it all—practical and fun

The Volkswagen ID.4, which went on sale in the US earlier this year, could turn out to be a very important vehicle for a couple of reasons. It’s the first of VW’s new-generation EVs to reach the US. That is, it’s the first to be built by the post-scandal, reformed and repentant VW, and the… Read more »

Equipmake and Beulas unveil electric double-decker bus with 250-mile range

Vehicle electrification specialist Equipmake and Spanish coachbuilder Beulas have partnered to develop an electric double-decker bus. The new Jewel E features an electric powertrain designed and developed at Equipmake’s facility in Norfolk, UK, along with a body produced by Beulas in Girona, Spain. Equipmake’s Zero Emission Drivetrain (ZED) is modular and scalable, capable of supporting… Read more »

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 »
