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 »
