Oceangoing ships, most of which are powered by heavy fuel oil, produce substantial amounts of CO2 and nitrogen oxide emissions. However, shipping companies are unlikely to begin electrifying them until the economic case for doing so becomes clearer. A new study from the University of California, Berkeley and Lawrence Berkeley National Laboratory indicates that nearly… Read more »

Kenworth pursues both BEVs and FCEVs
For heavy-duty truck manufacturer Kenworth, adoption of zero-emission trucks is seen as inevitable—the shift is being driven by both regulatory requirements and economic benefits. Speaking at a recent press event, Kenworth executives outlined the company’s electrification strategy, which includes investigating both battery-electric and hydrogen fuel cell technologies. As Fleet Owner reports, 17 US states and… Read more »
Protect heat-sensitive EV charging components with closed-loop enclosure cooling (Whitepaper)
Sponsored by Kooltronic Heat is a by-product and one of the greatest enemies of electrical and electronic components. In fact, the average reliability of electrical/electronic components drops by 50% for every ten-degree rise above the maximum device operating temperature. Electric vehicle charging stations are no exception. Lithium-ion batteries and other heat-sensitive equipment such as microprocessors… Read more »
Blue Bird offers turnkey charging solutions for electric school buses
Iconic school bus builder Blue Bird has expanded its electrification ecosystem with the launch of Blue Bird Energy Services, which provides turnkey charging solutions for electric school bus fleets. Blue Bird says it has nearly 650 electric school buses in operation today. The company builds a full range of electric school bus models, which offer… Read more »
The promise of wireless charging: smaller batteries, longer battery life, fewer charging stations
Q&A with Momentum Dynamics Wireless charging is nothing new—Charged has covered wireless EV charging since at least 2011—but it may be that its true value is only coming into focus now, as more and more commercial and transit fleets are electrifying. There are many reasons (safety, reliability, liability) that a fleet operator might not want… Read more »
The EV raw materials crunch: How bad, how long, how to solve it?
This article originally appeared in Issue 60: April-June 2022 Subscribe now Every new technology must overcome a series of temporary constraints on its way to widespread adoption. Since modern EVs appeared a decade ago, they’ve motored past many of these bottlenecks, (or hurdles, or roadblocks—pick your preferred metaphor). Range has increased, access to charging infrastructure has expanded,… Read more »
bp opens its first electric truck charging facility in Germany
For better or for worse, oil giant bp has become one of the major players in Europe’s public charging industry. Now the company’s Aral pulse brand has opened its first fast charging facilities aimed at the medium- and heavy-duty electric truck market. Aral’s retail site at Schwegenheim, Germany now has two 300 kW chargers for… Read more »
A closer look at brushed AC motors in EVs
Everything old is new again: BMW’s fifth-generation eDrive features a wound-field synchronous AC motor Brushed DC (and AC/DC universal) motors are much maligned for a number of reasons, but one of the chief—if, perhaps, somewhat exaggerated—complaints is that the graphite brushes, and the segmented copper commutator they ride on, wear out over time, all the while producing… Read more »
Marelli launches a new 800 V silicon carbide inverter platform
Marelli has developed a new 800 V silicon carbide inverter platform. “The new inverter platform based on our 800-volt silicon carbide power module technology allows it to serve applications where energy use is optimized, the performance is maximized and efficiency is dramatically improved,” says Dr. Razvan Panati, Head of Power Electronics Technology for Marelli’s Vehicle… Read more »
Startup led by Tesla alums aims to build electric RVs
As is the case with a legacy vehicle, towing a trailer with an EV greatly reduces range—as John Voelcker found in his recent test of a Ford F-150 Lightning (see the latest issue of Charged), towing can reduce range by 40% or even more. But what if the trailer had its own electric powertrain? That’s… Read more »
