The Good And Bad Of Bi-Directional Charging


Auto OEMs are starting to offer bi-directional charging in EVs, allowing batteries to power homes during outages or wherever else it is needed, and to smooth out any hiccups in the grid. But this technology also can shorten the lifetime of batteries, and it can open the door to more cyberattacks. The idea behind bi-directional charging is simple enough. EVs can store huge amounts of power, a... » read more

EV Charging Cybersecurity Challenges (Sandia National Labs)


A technical paper titled "Review of Electric Vehicle Charger Cybersecurity Vulnerabilities, Potential Impacts, and Defenses" was published by researchers at Sandia National Laboratories. Abstract: "Worldwide growth in electric vehicle use is prompting new installations of private and public electric vehicle supply equipment (EVSE). EVSE devices support the electrification of the transportat... » read more

Wave Hello To Improved Performance


The International Energy Agency (IEA) estimated that in 2019, approximately 33 percent of all transportation-related CO2 emissions were generated by buses and light to heavy commercial vehicles. Transitioning to electric drives in this sector could clearly have a significant impact on reducing our emissions, but electrifying such demanding vehicles is not an easy task. Many of the concepts... » read more

Equipment Suppliers Brace For GaN Market Explosion


A huge GaN market is opening up, driven by consumer devices and the need for greater energy efficiency across many applications. Suppliers are ready, but to fully compete with SiC in high-voltage automotive applications will require further technological developments in power GaN (gallium nitride). Still, the 2020s mark a very high-growth phase for GaN markets. Revenues in the power GaN mark... » read more

Challenges Grow For Modeling Auto Performance, Power


Rising complexity in automobiles is creating huge challenges about how to add more safety and comfort features and electronics into vehicles without reducing the overall range they can travel or pricing them so high that only the rich can afford them. While the current focus is on modeling hardware and software to understand interactions between systems, this remains a huge challenge. It req... » read more

What Quantum Batteries Have in Store


Quantum battery technology is approaching an inflection point similar to the one quantum computing crossed a decade or so ago, escalating it from a theoretical curiosity to an engineering challenge worth solving. Quantum batteries exploit the strange physical laws of the very small — the quantum world — to gain performance advantages over classical batteries. Recent research on charging ... » read more

Compound Semiconductor Innovation Advances EVs And Other Green Technologies


As the world works to reduce greenhouse gas emissions, global adoption of electric vehicles (EVs) is driving an increased demand for high-power, energy-efficient compound semiconductors, such as silicon carbide (SiC)-based components, throughout the entire EV assembly process. Renewable energy technology is now at the forefront of climate-forward research, with accelerating EV sales playing�... » read more

GaN ICs Wanted for Power, EV Markets


Circuits built with discrete GaN components may get the job done, but fully integrated GaN circuits remain the ultimate goal because they would offer many of the same advantages as integrated silicon circuits. These benefits include lower cost as the circuit footprint is scaled, and reduced parasitic resistance and capacitance with shorter interconnect runs. In addition, improved device perf... » read more

Research Bits: March 15


Interferometer on chip Researchers at the University of Rochester developed an optical interferometer on a 2mm by 2mm integrated photonic chip that is capable of amplifying interferometric signals without a corresponding increase in extraneous noise. Interferometers merge two or more sources of light to create interference patterns that provide information able what they illuminate. “If y... » read more

Making Batteries Denser And Safer


Battery technology is improving swiftly, driven by the rapidly rising demand for electric vehicles and the vast body of knowledge developed by the semiconductor industry. The market for electric vehicles (EVs) is on a fast upward trajectory, with global sales predicted to grow more than 12 times to more than 31 million vehicles. In fact, EVs will account for almost a third of new vehicle sal... » read more
