There seems to be an endless array of electric motor topologies, architectures, and configurations. Among the many design choices that engineers face is the shape of copper wire that is wound in the stator. In a new paper published in the IEEE Transactions on Industry Applications, researchers compared using flat wire hairpin winding and stranded… Read more »

A look at Lucid Motors: Q&A with CTO Peter Rawlinson
The legacy automakers are slowly and methodically developing new EVs, with various levels of enthusiasm, but the most ambitious plans for new vehicles are coming from a handful of EV startups. Most of these pioneers of the new auto industry share a formula: deep-pocketed investors (many from China), former Tesla employees on staff, and plans… Read more »
PNNL research finds that optimal salt concentration increases battery life
Researchers at the DOE’s Pacific Northwest National Laboratory have discovered that the “special sauce” of batteries is all about the salt concentration. By getting the right amount of salt right where they want it, they’ve demonstrated that a lithium-metal battery can undergo about seven times more charge/discharge cycles than batteries with conventional electrolytes. Finding an electrolyte solution… Read more »
SF Motors teases two new EVs, plans to begin production this year
After two years in stealth mode, Santa Clara-based SF Motors recently announced details of two upcoming EVs, the SF5 and the SF7. The SF5 will be available for pre-order by the end of 2018 and is scheduled to hit the road in 2019. The company plans to begin vehicle production this year at its facilities… Read more »
Aqueous anode enables super-fast charging
An international team of scientists, including researchers from the DOE’s Argonne National Laboratory, has discovered an anode material that enables super-fast charging and offers stable operation over many thousands of cycles. In a recent article in Nature Communications, Argonne Battery Scientist Jun Lu and colleagues describe a water-bearing compound, lithium titanate hydrate, that could replace… Read more »
ABB becomes title sponsor of Formula E
Since its first race in Beijing in 2014, Formula E has been raising awareness of EVs around the world, while providing a platform for manufacturers to test new technology under racing conditions. Now the Swiss electronics giant ABB has become the title sponsor – the series will henceforth be known as the ABB FIA Formula… Read more »
The Goldilocks zone: Calienté explains that battery pack heating is just as important as cooling
In the eyes of an EV driver, the success of the battery is measured in a completely binary way: does the battery last the life of the vehicle, or not? In fact, the best praise you can give any battery – whether in your laptop, phone, or EV – is not to have to think… Read more »
Lithium-ion battery inspired by safety glass could reduce fire risk
Researchers at the Oak Ridge National Laboratory (ORNL) have developed a way to mitigate the risk of battery failure during automobile accidents by including slits along the electrodes. In “Limiting Internal Short-Circuit Damage by Electrode Partition for Impact-Tolerant Li-Ion Batteries,” published in the journal Joule, the research team explains how this technology could allow manufacturers… Read more »
Predicting the properties of lightweight carbon fiber composites
Carbon fiber-reinforced plastics represent a promising lightweight replacement for heavy steel. However, for carbon fiber to be widely adopted, new, more economical composites need to be developed. Unfortunately, carbon fiber properties are difficult to model, as they depend on complex features such as fiber loading, length distribution and orientation. Now researchers at the DOE’s Pacific… Read more »
BMW partners with Solid Power to develop solid-state batteries
Solid Power has grown rapidly since it was established in 2012 as a spin-out company from the University of Colorado. The battery developer recently moved into a new facility in Louisville, Colorado that will triple its footprint. Now the company has announced a partnership with the BMW Group to develop its solid-state batteries for EV… Read more »
