Avoiding motor demagnetization: John Wanjiku, Technical Specialist at Mentor Graphics, explains the goals of a detailed traction motor design analysis. Neodymium permanent magnets are used in EV traction motors because of their powerful magnetic fields and relatively strong resistance to demagnetization, but they tend to lose their magnetism when exposed to excessive operating temperatures, opposing… Read more »

California makes VW funds available for zero-emission freight and marine projects
The California Air Resources Board has announced that the first installment of $35 million in VW Environmental Mitigation Trust funding for Zero-Emission Freight and Marine Projects throughout California is now available via a competitive solicitation. A second solicitation offering an additional $35 million is expected to be released in mid-2022. Eligible projects: Scrap and replace… Read more »
Air pollution returns to “normal,” as new study shows EVs save $10,000 each in health costs
Amid the hardships of the recent pandemic-inspired lockdowns, some saw signs of hope for the future in the clear skies and quiet streets. Could the views of distant mountains from Los Angeles to New Delhi be made permanent? The object lesson provided by the lockdowns was that, if we want cleaner air, we know how… Read more »
Seven future electric pickup trucks. Maybe.
Over the first 10 years of their existence, most modern battery-electric cars have been compact hatchbacks or Teslas. While a few are marketed as crossover utility vehicles, none have been the full-size pickup trucks that make up a huge and very profitable segment of US vehicle sales. That’s about to change. What follows is a… Read more »
Solid-state battery tech: What’s close to commercialization, and what’s still years away?
With a fresh round of funding, Wildcat Discovery Technologies is busy expanding its facilities, building up its battery team and doubling down on promising solid-state research projects. We asked the energy storage experts to help clear up the hype around solid-state batteries. Whenever Charged needs to better understand the complexities of the latest and greatest battery… Read more »
New research: Using ionic liquids to recycle neodymium magnets
Researchers have demonstrated the use of ionic liquids for recycling bonded neodymium (NdFeB) permanent magnets—-the type often used in EV motors. Their work, which could ease the strain on rare earth materials, is published in the open-access journal Green Chemistry. “Ionic liquids (ILs) are known to be excellent green solvents for many types of synthetic… Read more »
Volkswagen Group forms joint venture to build fast charging stations for Chinese market
Volkswagen Group Components and startup Shanghai DU-POWER New Energy have formed a joint venture to produce “flexible quick charging stations” in China. The two companies will each own 50% of the JV, which will be located in the Suzhou Wuzhong Development Zone, near Shanghai. Series production is scheduled to start in the second half of… Read more »
Enevate says its silicon-dominant anode technology is ready for EV production
Q&A with Enevate’s Founder and CTO Dr. Benjamin Park Introducing silicon into automotive-grade lithium-ion cells has been a major topic in the EV industry in the past decade. Silicon is widely considered to be the next big thing in anode technology, because it has a theoretical charge capacity ten times higher than that of typical graphite anodes…. Read more »
UK must develop battery recycling infrastructure, study finds
Governments and industry in the United Kingdom must develop a recycling infrastructure for EV batteries, according to a new study led by the University of Birmingham. The researchers calculated that one million EVs sold in 2017 alone will result in 250,000 metric tons of unprocessed waste once these vehicles reach the end of their lives…. Read more »
Argonne develops electrolyte for next-gen lithium battery with silicon anodes
Researchers at the DOE’s Argonne National Laboratory have developed a new electrolyte mixture and a simple additive that could have a place in the next generation of lithium-ion batteries that feature silicon anodes. The report findings were published in July in the journal ACS Applied Materials & Interfaces. Scientists have long seen the silicon anode… Read more »
