Tesla Model 3: Will this machine kill the Oil Age?

It’s hard to overestimate the importance of the Tesla Model 3 (although the media has been doing its best). There’s no question that it’s a momentous motorcar on (at least) three levels. First, Model 3’s success is widely assumed to be an existential issue for the company – if it fails to deliver on its… Read more »

What’s going to happen with US emissions regulations?

Q&A with emissions standards expert Michael Steel of the law firm Morrison & Foerster For better or for worse, the proliferation of plug-in vehicles that has occurred over the past few years is largely the result of government regulation. Automakers are producing some excellent EVs, but (except for a certain California carmaker) to put it… Read more »

Continental says its AllCharge system will provide maximum power, no matter the charging station

Continental’s AllCharge is a technology that aims to provide a universal charging experience for EVs. The way it sets out to do this is simple, yet surprisingly unique: Instead of using purpose-built charging components, AllCharge makes use of the existing components of an EV’s electric powertrain to charge the vehicle. “Normally you have to swallow… Read more »

Flying electric: Both startups and industry giants push ahead with electric airplanes

In the popular imagination, aviation represents the last frontier for electrification. Considering the weight and limited range of batteries, an electric airplane might seem practically impossible. However, while electric long-haul airliners probably lie pretty far in the future, the fact is that, in some applications, the technical obstacles to electrified aircraft are not as formidable… Read more »

A closer look at rare earth permanent magnets

Rare earth magnets have gotten a lot of coverage in the EV press over the years for being expensive – especially back in 2011 when a supply disruption in China sent the prices up anywhere from fivefold for neodymium to 20-fold for dysprosium over the course of a few months – yet they are still… Read more »

Mitsubishi Electric increases reliability of automotive power modules with direct lead bonding

Much as humans need a heart to distribute energy throughout our bodies, EVs need a heart to transfer energy from their batteries to their motors. This “heart” of an EV is called a power module, and it’s responsible for driving the vehicle’s propulsion unit as efficiently as possible. Considering the critical importance of power modules,… Read more »

Dynamic wireless charging: What’s feasible? Q&A with Qualcomm’s Graeme Davison

Charged has been writing about Wireless Electric Vehicle Charging (WEVC) technology for several years. As far back as 2012, automakers have said they plan to include the technology on future EVs. While those plans have been delayed for a few different reasons – interoperability standards, uncertainty in the EV market, etc. – it now appears… Read more »

VGI: California’s cooperative effort to capitalize on EV-grid potential

Last September, Carla J. Peterman, a commissioner with the California Public Utility Commission (CPUC), outlined new requirements for California’s investor-owned utilities that would measurably advance commitments to transportation electrification (TE). One technical requirement singled out by Peterman was addressed in a document called “Enabling Vehicle-Grid Integration Through a Communications Standard,” which focused on the question… Read more »

Alta Motors says its electric dirt bike has world-class energy density

Alta Motors claims that its dirt bikes have a battery pack with energy density that’s among the highest of any production vehicle. With help from Scheugenpflug’s custom production equipment and Wevo-Chemie materials, the motorcycle builder says its thermal design was the key to achieving that. Seven years ago, a group of motorcycle and off-road dirt… Read more »

MSC’s laminated steel and aluminum will reduce noise and vibration while cutting mass

When it comes to EVs, every pound matters. There is a direct relationship between a vehicle’s weight and the requirements of its expensive battery back, so automotive engineers will explore every possible measure to reduce vehicle mass. However, one of the ways that engineers have traditionally achieved desirable properties in the domain of Noise, Vibration,… Read more »
