Lordstown said it will try to sell its assets, and reduce its 243-person staff to a… Read more »
Winners and losers emerge as the Tesla charging bandwagon gathers speed
In a decade of covering the EV industry, I can’t recall ever seeing such immediate and near-universal praise for any development as I have for the news that Ford and GM will partner with Tesla to give their EVs access to the Supercharger network. The news broke in two waves, each of which swamped the… Read more »
CEO Jim Farley explains how Ford is learning from Tesla, marketing EVs as “digital products”
Ford CEO Jim Farley is no stranger to EVs—before he joined Ford, he worked at Toyota, and was deeply involved in bringing the Prius to the US market. In a wide-ranging recent interview with Fully Charged’s Robert Llewellyn, Farley talks about how he is shepherding his company through the process of electrification. Farley understands that… Read more »
Pre-Switch includes remote update and analysis features in Pre-Flex controller for SoC
Pre-Switch, a producer of AI-based soft-switching power systems, has allowed the reprogramming of its Pre-Flex motor/inverter controller SoC for EVs, and has incorporated a digital oscilloscope, allowing designers to remotely diagnose and make modifications. Pre-Flex ICs have AI algorithms for soft switching across all operating voltages, load situations and temperatures and adjust cycle-by-cycle. Pre-Switch technology… Read more »
European HEFT project targets cheaper, more efficient, power-dense motor for EVs
In a €4-million HEFT research project directed by Mondragan University, eight EU partners including GKN Automotive will create a “lower-cost, more efficient and power-dense” permanent magnet motor for EVs. HEFT is an EU Horizon 2020 project focused on designing and manufacturing EV motors with reused and recycled permanent magnets. HEFT recommends energy-efficient rare earth synchronous… Read more »
Why California needs to mandate bidirectional charging capabilities for EVs
Explaining the benefits of bidirectional EV charging: Q&A with Nuvve CEO Gregory Poilasne The term “game-changing” gets thrown around a lot in the EV field, but if there’s any new technology that really does deserve to be described this way (as California Governor Gavin Newsom recently did), it’s bidirectional charging. Going bi adds several nifty… Read more »
Stellantis offers buyouts to thousands of employees, says EVs are to blame
The legacy auto industry is facing perhaps the greatest restructuring in its history, and one unfortunate aspect of this is a growing wave of layoffs and buyouts. Of course, technological and geopolitical changes often lead to job losses. In the past, labor advocates have deplored the relocation of auto plants to low-wage countries and non-union… Read more »
Alternatives to permanent magnet motors in EV traction applications
In my very first article for Charged over 10 years ago, I opined that the Switched Reluctance Motor, or SRM, would eventually come to dominate the EV traction market, if for no other reason than the fact that it is almost as cheap as dirt to manufacture. I won’t sprain my shoulder patting myself on… Read more »
Pre-Switch claims 98.5% efficiency for reference inverter
Power architecture developer Pre-Switch has announced test results of its CleanWave2 reference inverter at 100 kHz switching speed that show 98.5% efficiency at 5% load and peak efficiency of 99.57%. According to the company, its architecture, efficient at both low load and full load, eliminates switching losses and enables 10 times higher switching frequencies, resulting… Read more »
