A glimpse into the auto shop of the future at Tampa Hybrids

EVs haven’t been around long enough, or in great enough numbers, for any large-scale market in replacement batteries to develop. However, Toyota’s Prius hybrid went on sale in the US in 2000, and has sold well over two million units. There’s a lively market for replacement batteries, with both OEM and aftermarket options available. For… Read more »

Electrify America begins building a nationwide network of metro, highway, workplace and community chargers

The two-billion-dollar 10-year investment represents the largest of its kind so far. In the chaos that is human affairs, bad intentions sometimes eventually lead to good results. As atonement for Volkswagen’s criminal actions in what we like to call the Dirty Diesel Debacle, government regulators have forced the automaker to invest substantial resources in promoting… Read more »

2019 Jaguar I-PACE: An apex brand pounces on the electric crossover scene

Believe it or not, we may have a BEV SUV turf war on our hands. Many of the major automakers have announced plans to produce all-electric crossovers, including Mercedes, Volvo, Hyundai, Kia and Volkswagen – not to mention the onslaught startups like SF Motors, Faraday Future, Byton and Rivian. The all-electric Audi e-tron SUV is… 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 »

Top circuit protection requirements to consider when designing an automotive battery pack

Littelfuse helps the auto industry navigate new electrical engineering challenges When engineers design a battery pack, they tend to focus first on its core functionality and value proposition. For a high-end energy storage device, those core attributes are typically things like total pack energy density, cost minimization, packaging efficiency, peak power and state-of-the-art thermal management….

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 »
