Research firm Adamas Intelligence has reported that 93 percent of all passenger EVs sold in 2018 used permanent magnet (PM) traction motors, an increase of 1 percent from 2017. PM traction motors use neodymium iron boron (NdFeB) permanent magnets in the rotor, which spin the rotor in response to a rotating magnet field produced in… Read more »

Audi joins the class of 2019 with the e-tron
A new generation of EVs is beginning to appear on the roads, and these cars have what it takes to compete head-to-head with fossil fuel vehicles. They offer more than enough range to cover anyone’s daily commute, and thanks to vast new charging networks such as Electrify America and Europe’s Ionity, they are increasingly able to… Read more »
UK lithium sulfur battery firm OXIS secures funding to expand to Brazil
UK battery technology company OXIS Energy will receive a £3.7-million investment from the Brazilian private equity fund Aerotec, paving the way for OXIS to open a subsidiary in Brazil. The agreement provides for a Brazilian team to be trained at OXIS Energy’s headquarters in Oxford, as well as the creation of an R&D center in… Read more »
New study: EVs emit less greenhouse gases than diesels, even in coal-heavy regions
The myth of the “long tailpipe” – the idea that, because EVs are partially powered by dirty coal, they are no cleaner than legacy vehicles – just won’t go away. In 2012, a detailed study from the Union of Concerned Scientists found that even if it were charged 100% from coal, an EV would still… Read more »
Teardown of Chevy Bolt points to massive disruption ahead
It’s not unheard-of for financial analysts to tear down a vehicle to get an accurate estimate of what it costs to produce. Back in 2015, a consulting firm took apart and reverse-engineered a BMW i3. More recently, a team from UBS disassembled a Chevy Bolt and published a cost analysis of the new EV. However,… Read more »
Texas Mineral Resources to establish lithium subsidiary to market Round Top lithium
Texas Mineral Resources Corp. (TMRC), an exploration company targeting rare earths and other high-value industrial minerals, plans to establish a separate subsidiary to market the lithium it hopes to produce from its poly-metallic Round Top deposit. Recent column leach tests found that Round Top rhyolite crushed and leached in sulfuric acid for 60 days (what… Read more »
2016 Chevy Volt: GM’s top electrification engineers on designing the all-new EREV
When the Chevrolet Volt was launched at the end of 2010, I must confess that I gave it little chance of success. It seemed like an awkward compromise – buyers who wanted to go electric would surely prefer a pure EV, and buyers who weren’t ready to take that plunge had every reason to stick… Read more »
Tesla locks up long-term lithium supply
To produce EVs, you need batteries. To build batteries, you need lithium. That’s why Tesla has signed a long-term contract with a pair of mining companies to supply lithium hydroxide from a site in northern Mexico. Bacanora Minerals Ltd and Rare Earth Minerals PLC are partners in a joint venture called the Sonora Lithium Project…. Read more »
New report from Germany assesses over 500 EV models
A new study from the German Aerospace Center (DLR), in partnership with the Wuppertal Institute for Climate, Environment and Energy, aims to present a comprehensive picture of current progress in electromobility, and to assess the position of German companies in the rapidly developing market. The DLR scientists developed a database of every known electric passenger… Read more »
PowerGenix demonstrates the benefits of nickel-zinc batteries for stop-start and auxiliary applications
PowerGenix, a supplier of automotive nickel-zinc (NiZn) batteries, has completed a product evaluation test plan with the Institute of Automotive Technologies Dresden (IAD). IAD evaluated the capabilities of NiZn batteries used as a 12 V auxiliary power unit for plug-in vehicles, or as a 12 V starter battery for stop-start applications. “The unique cost and… Read more »
