After decades of patent-protected breakthroughs, PolyPlus stands poised to make its first commercial move from its trio of power-dense battery technologies: lithium-sulfur, lithium-water, and lithium-air. It’s a balmy, 95-degree August day in the nation’s capital, but Steven J. Visco, PhD, the CEO, CTO, and co-founder of PolyPlus, sits in the climate-controlled comfort of the White House… Read more »
Regenerative braking (usually called regen for short) is simply the act of turning a motor into a generator, so that it slows down the load it was previously driving. Instead of converting momentum into heat with friction brakes, regen puts some of that energy back into the traction pack, not only saving wear on the… Read more »
Microvast is the largest battery company you’ve probably never heard of. That’s because they are their own best customer. Instead of pitching their proprietary lithium–titanate technology to vehicle builders, the company identified a well-suited niche for their batteries and set out to demonstrate a sustainable model. Primarily a research and development focused chemical company, Microvast… Read more »
A new public-private consortium, seeks to leverage the academic foundation and fertile entrepreneurial ground of the Bay Area to streamline new battery technology development.
Topping the list of EV inhibitors are cost and consumer perception of long-term reliability of the vehicle. After batteries, power electronics contribute the greatest cost to EVs, when compared to a traditional internal combustion engine (ICE) vehicle. Additionally, inverters and converters are among the most stressed powertrain components. Increasing inverter performance, reliability, and lifetime –… Read more »
Envia Systems crushed the record for energy density of an automotive rechargeable Li-ion battery at 400Wh/kg. Now all the small start-up has to do is partner with everybody, become the industry standard, and change the world. Most of us know the public library as a place to get some free Wi-Fi, meet up with people for… Read more »
News flash: EVs will suffer from manufacturing defects at approximately the same rate as their gas-fueled cousins. You can Six Sigma processes until you’re blue in the face, but machines designed and built by us mere mortals will always find a new way to break unexpectedly. So what happens when they do? If the issue… Read more »
Want to increase the range of your EV without adding capacity to the costly battery pack? Optimize. In parallel with global research efforts to improve the power density of batteries, many are looking for new ways to use less energy per mile. Mitsubishi’s New Motor Mitsubishi Electric is hard at work redefining what a… Read more »
