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 »
Argonne reviews 40 EV market analyses from 16 countries
A team of researchers at the DOE’s Argonne National Laboratory has conducted a review of 40 automotive market studies from 16 countries, including the US, Germany, China, South Korea, the UK and Ireland. These studies modeled the decision factors that drive consumers to buy plug-in vehicles (PEVs). The study addressed such issues as: projected market… Read more »
Robert Bollinger is building unique EVs, and a one-of-a-kind EV company
Bollinger Motors is not following the typical EV startup formula. Instead of building a luxury sedan, it’s building a rough and ready work truck. It has no strategy to evolve into a mass-market automaker, but intends to find a niche as a low-volume brand. As far as we know, the company has no former Tesla… Read more »
A closer look at film capacitors
Plastic film capacitors relentlessly continue to take over many of the duties in EV power electronics that were once performed by the venerable aluminum electrolytic type, mainly because film capacitors exhibit much lower losses and have a much longer operational lifespan, especially at ambient temperatures in the 75-85° C range. The tradeoff is that film… 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 »

Wildcat sorts through the avalanche of new battery materials to find the best
As automakers and cell manufacturers begin to realize the complexity of benchmarking new battery materials, Wildcat Discovery Technology is using its high-speed R&D technology to help find clarity If you follow battery technology news on a regular basis as we do, it’s easy to get overwhelmed by the volume of new announcements. There are… 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 »
