Swedish researchers: Carbon fiber can serve as both body panel and battery
It’s one of the dilemmas of EV design: It’s imperative to keep a vehicle’s weight as low as possible, but the most critical component – the battery – is necessarily quite heavy (and bulky). A little outside-the-box thinking yields an elegant solution – make the box the battery. In other words, design a battery material… Read more »
Tesla shares all of its patented technology
Last week, while speaking at the company’s first-quarter shareholders’ meeting, Elon Musk expressed frustration with the other automakers for moving so slowly into EVs, and hinted that he’s thinking about offering them a helping hand. “I’m contemplating doing something fairly significant on that front, which would be kind of controversial with respect to Tesla’s patents.” Today,… Read more »
Echo Automotive aims for the plug-in fleet sweet spot
The commercial fleet market is one of the most exciting frontiers in the electromobility revolution, not only because of the enormous potential for fuel savings, but because it offers opportunities for a smaller company, which can hope to carve out a lucrative niche developing a powertrain solution, without the need to build the sort of… Read more »
The Buckeye Bullet: A student-built EV that’s racing towards 400 mph
As it stands today, Ohio State’s Buckeye Bullet 1 holds the US record speed for battery electric vehicles (BEVs) at 314.958 mph, its Venturi Buckeye Bullet 2 holds the world record for hydrogen fuel cell electric vehicles at 302.877 mph, and the Venturi Buckeye Bullet 2.5 holds the world record for BEVs at 307.666 mph. … Read more »
Silicon carbide power semiconductors improve hybrid fuel efficiency
Toyota and Denso have collaborated to develop a silicon carbide (SiC) power semiconductor for use in power control units (PCUs). Using SiC power semiconductors, Toyota aims to improve hybrid fuel efficiency by 10 percent and reduce PCU size by 80 percent, compared to current PCUs with silicon-only semiconductors. The PCU is a critical component of… Read more »
Brammo CEO Craig Bramscher on the future of the leading electric motorcycle company
Electric motorcycles are one of the most interesting stories in the EV world today, both because of their recent impressive accomplishments on the racetrack and because of the future potential for high-volume sales, especially in international markets. Ashland, Oregon-based Brammo is one of the leading makers of two-wheeled EVs, and its story has much in… Read more »
Study finds electromagnetic fields in EVs not a safety issue
An EU-funded study has found that electrified vehicles do not expose passengers to higher electromagnetic fields than those recommended in international standards (and neither do ICE vehicles). The study EM Safety, which involved the independent research organization SINTEF and nine other European companies and research institutes, is the most comprehensive ever carried out in this… Read more »
OLEV Technologies’ dynamic wireless inductive system charges vehicles while in motion
When one thinks of Nikola Tesla and electric vehicles, the obvious connection points to Elon Musk’s favorite part-time project. However, we also have to give the Serbian inventor proper credit for pioneering technology that eventually may become even more important to EVs than battery breakthroughs. Tesla’s obsession with wireless power transmission defined much of his… Read more »
Exhaustive infrastructure testing: Converging industries present challenges for automakers
In the past few decades, the automotive industry has seen a shift from traditional mechanical systems to a world dominated by electronics, chips and software. If you go to a car show and look in the engine compartment of an older vehicle, you’ll see only a handful of connections from the cockpit. Modern vehicles, however,… Read more »
