North Carolina State University (NCSU) researchers have developed a medium-voltage fast charger (MVFC) that they say offers 60% less power loss than conventional systems, is only a tenth the size, and delivers similar charging times. Armed with this technology, the team is working towards a multi-vehicle charger capable of even faster charging. Current 50 kW… Read more »

ORNL develops 120 kW wireless charging prototype with 97% efficiency
The DOE’s Oak Ridge National Laboratory (ORNL) has created a 120 kW wireless charging system with a mere six-inch air gap between the battery and coils. Tests have shown the experiment to be 97% efficient, rivaling wired high-power fast chargers. Their previous demonstration was a much smaller 20 kW system currently being modified for several… Read more »
Dyson selects Singapore for EV factory site
The British firm Dyson, famous for its innovative vacuum cleaners and hand dryers, has chosen Singapore as the manufacturing site for its upcoming EV. Dyson, which is investing some $2.6 billion in its effort to expand into automobiles, says it will complete the factory by 2020, and hopes to bring its first model to market… Read more »
Porsche dealers will have to share the cost of fast chargers
Back in March, a Porsche exec said that the brand expected to make a profit from its planned network of fast chargers, a comment that was met with much skepticism in the EV industry. Now the company is sending a rather different message, saying that its US dealers will be expected to pony up between… Read more »
One Republican Senator wants to extend federal EV tax credit, another wants to end it
Support for EVs on Capitol Hill does not divide neatly along partisan lines, as a pair of dueling bills in the Senate illustrates. This week, Senator Dean Heller (R-Nevada) proposed legislation that would lift the current cap on EV tax credits. Under current law, once a particular automaker sells 200,000 EVs, the tax credit will… Read more »
European automakers fear EVs will eat into auto industry profits
Several new electric models made their debut at the recent Paris Motor Show, including PSA’s DS3 Crossback and the Mercedes EQC, but off the noisy show floor, away from the turntables, hors d’oeuvres and booth bunnies, executives are ruefully acknowledging that the transition to EVs will mean an end to the record profits of recent… Read more »
Motor manufacturing: Tempel builds state-of-the-art factories to meet automaker’s requirements
Stamping precision parts for automotive-grade motor manufacturing The demands of the automotive industry are unlike any other. Carmakers require that their suppliers deliver millions of parts with incredibly tight tolerances that will not fail after a decade of daily use. The companies that manufacture parts for ICEs have grown increasingly sophisticated and disciplined in the… Read more »
Cummins, the diesel engine powerhouse, has had a busy year expanding its EV systems development
Cummins is a huge presence in the diesel engine market around the globe. The company designs, manufactures and sells billions of dollars’ worth of diesel engines (and some engines powered by “alternative fuels” such as natural gas). Ranging from 2.8 to 95 liters, the company’s engines are found in nearly every type of vehicle and… Read more »
Regenerative braking: A closer look at the methods and limits of regen
All motors are generators, the old saying goes, with the caveat that few types are equally good at both modes of operation, and some are downright awful as generators (a classic example being the single-phase shaded pole induction type, used in myriad small appliances the world over). Fortunately, both types of AC motor commonly used… Read more »
Hubject connects over 70,000 chargers in 26 countries, and it’s bringing that expertise stateside
Easier EV charging interoperability en route to North America When your EV is running low on range, the last thing you want to do is waste time hunting down a spot to charge it. When driving an ICE vehicle, you can pull up to any gas station and fill your tank. With an EV, it’s not… Read more »
