Tesla isn’t like other companies, and you can never tell how Wall Street will react to a particular quarterly earnings report. Like gourmands digesting a culinary oeuvre, those of us who aspire to be seen as wise have learned to wait a day or so to let things settle before passing judgement (or making stock… Read more »

Iron trifluoride cathode could greatly increase energy density
Researchers from the University of Maryland and the DOE’s Brookhaven National Laboratory have developed a cathode material containing iron trifluoride (FeF3) that they say could triple the energy density of Li-ion batteries. Their research was published in Nature Communications. “Compared to the large capacity of the commercial graphite anodes used in lithium-ion batteries, the capacity of the cathodes is… Read more »
ON Semiconductor announces rugged automotive SiC Diodes
ON Semiconductor has introduced a robust line of automotive-grade silicon carbide (SiC) Schottky diodes. The AEC-Q101 diodes can handle high surge currents and are meant to operate from -55° to 175° C. There are several reasons why SiC diodes are ideal for automotive applications. They are smaller and cheaper compared to alternatives, have higher power densities, and create… Read more »
Wolfspeed Technology introduces third-gen 1,200 V SiC MOSFET
Only one year after they were first introduced, Cree’s Wolfspeed Technologies has announced its third generation of 1,200 V SiC MOSFETs. Designed for EV powertrain applications, Wolfspeed claims that the MOSFET has the highest figure of merit on the market today, with low drain-source on resistance (RDS) performance and the industry’s lowest switching losses. Samples are currently available… Read more »
How to protect circuits in battery management systems
Sponsored by Littelfuse By Carlos Castro, Global Director Marketing Automotive Electronics, Littelfuse, Inc. As hybrid and electric vehicles roll closer to battery power drive systems with 48V or higher, the lithium-ion battery in a closed system is the clear leader for power. Lithium-ion gets high marks in cost, energy efficiency, temperature performance, power-to-weight ratio and lifecycle…. Read more »
New UCS report indicates automakers have lost interest in reducing emissions
The Union of Concerned Scientists has issued a new report that ranks the environmental performance of global automakers. It’s no surprise that Tesla topped the rankings by a wide margin. (Yes, the report considers the full lifecycle of vehicles, including emissions associated with manufacturing and the production of fuel.) However, EV fans may be surprised… Read more »
Tecnomatic helps automakers design specialty assembly processes for advanced stator technologies
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 »
Steady growth of Nordic plug-in sales falters
Plug-in vehicle sales in the Nordic countries have been soaring for over two years, setting one sales record after another. However, that trend stalled in the first quarter of this year, Insero reports. In the first three months of 2018, 24,893 plug-in vehicles were sold in Norway, Finland, Sweden, and Denmark, compared to 27,640 sold… Read more »
JetSuite to buy up to 100 Zunum Aero hybrid planes
Private aviation company JetSuite has announced plans to add up to 100 Zunum Aero electrified aircraft to its fleet. Washington-based Zunum Aero, profiled in the July/August issue of Charged, is developing a “hybrid-to-electric” plane with a capacity of 12 passengers, a maximum cruise speed of 340 mph and a take-off distance of 2,200 feet. The aircraft is optimized… Read more »
