How can quantum sensors and quantum batteries improve electric vehicle operation?
In the near term, quantum sensors are being developed that can more accurately measure EV battery capacity, assess battery safety, and reduce vehicle weight. In the longer term, quantum batteries have been proposed that could dramatically improve the speed and efficiency of battery charging. The energy remaining in an EV battery has been estimated using…
February 2024 Issue: Power Electronics Handbook
Cold starts, hot power markets, and great expectations Recent cold spells across the United States have shifted the focus from “range anxiety” in electric vehicles (EVs) to concerns about their performance in cold…how they start, and how far they can go. Buzzworthy? Apparently. Newsworthy? Maybe, but it’s not new news. Reflecting on a youthful…
Research shows improvements for fast-charging of Li-ion batteries
Researchers at Chung-Ang University used high-concentration electrolytes to improve safety and prevent cell swelling caused by lithium plating. To achieve a greater adaption of electric vehicles, the automotive industry needs fast-charging batteries that don’t compromise energy density. Lithium plating for ultra-fast charging raises safety concerns due to high cell polarization, requiring careful attention. During fast…
