With disenchantment in lithium-ion technology on the rise, lead-acid batteries may be poised to play a bigger role in green vehicles.
Automakers are said to be taking a closer look at lead-acid, in hopes that the century-old chemistry could serve in future vehicles that employ mild hybrid and start-stop powertrains. ”When I conceived of this company two-and-a-half years ago, the interest in lead-acid technology was zero,” Subhash Dhar, founder and CEO of Energy Power Systems (EPS), maker of a new lead-acid battery chemistry, told Design News. “Today, on a one-to-10 scale, it’s a seven.”
Only reinforces my belief that battery-powered electric vehicles aren't going anywhere in the foreseeable future. It takes a step function increase in battery technolgy to make battery electrics interesting, and sticking with lead-acid ain't it.
I keep rooting for hydrogen-reformer/fuel cell powered EVs, myself. A credible solution without the range anxiety.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
