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 »

Between the wheels: AxleTech goes electric

Can a company that’s 100 years old be called a startup? Mary Petrovich, Executive Chairman of AxleTech, certainly thinks so. AxleTech was founded in 1919 as Wisconsin Custom Built Axles, and has seen a century’s worth of sales, acquisitions, and rebrandings since then. Petrovich herself brought AxleTech back from the brink of failure not once,… Read more »

Tesla’s top motor engineer talks about designing a permanent magnet machine for Model 3

Most mainstream EVs from major automakers have used some form of permanent magnet traction motor technology, with two high-profile exceptions: Tesla’s Model S and Model X both use induction motor technology. Internet engineering forums are full of compelling arguments for using both technologies in vehicles, as well as loads of speculation on what drove Tesla… Read more »

Ionic Materials emerges as a leader in solid-state batteries by focusing on polymer science

Mike Zimmerman, CEO and founder of Ionic Materials, has this to say about his company: “Ionic will play a major role in the solution to the world’s energy problems.” That’s a pretty bold statement. But then again, Mike Zimmerman is a pretty bold man. An experienced polymer scientist, Zimmerman has worked on a number of… Read more »

A closer look at energy consumption in EVs

When it comes to factors that affect energy consumption in EVs, the big kahunas are weight and wind resistance (aka CdA), but there are other factors that can have a surprisingly outsized effect and that tend to be overlooked, such as the use of climate control (AC, of course, but especially heat). Conversely, one factor… 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 »

A closer look at power factor correction

Power Factor Correction (PFC) used to be something that electronics manufacturers only grudgingly added to a product – usually because of complaints about breakers tripping prematurely, or to meet regulatory requirements in the EU – but these days PFC is showing up in more and more products. While one should never underestimate the ability of… Read more »

From rapid prototyping to EV production with Pi Innovo’s M560 OpenECU

When you see the name Pi Innovo, your first thought might be of the famous mathematical constant that begins with 3.14. If you read it too quickly, you might be reminded of Pinocchio, the delightful tale of a physically deformed puppet. But from now on, when you see Pi Innovo, here’s what you should think… Read more »

Making a motor: Many automakers rely heavily on third party motor-winding experts like Odawara Engineering

Electric motors are everywhere: in household appliances, in hand tools, in buildings, in consumer electronics, and increasingly in automobiles. Motors are used in windshield wipers, power windows, throttle controllers, and, more and more, in the drivetrains of electrified vehicles. Electric motors abound, and Odawara Engineering knows how to make them. Charged spoke with Odawara’s Chris… Read more »
