Elon Musk raised some eyebrows when he announced that the new Tesla Roadster will do 0-60 in 1.9 seconds and have a range of 620 miles. That would make it not only by far the longest-range EV in existence, but also the quickest car ever produced. “These numbers sound unreal but they’re not,” said Musk…. Read more »

Fisker files patents on solid-state battery tech
Reborn automaker Fisker has filed patents for a new type of solid-state battery technology that it says could lead to much greater energy density and faster charging times. According to Fisker, current limitations of solid-state technology include low electrode current density, limited temperature ranges and non-scalable manufacturing processes. Other drawbacks include: low power and low… Read more »
Long aluminum, double-sided chip cooling solutions enhance electrified vehicles
Sponsored by Dana. Today, original equipment manufacturers (OEMs) are looking for cooling solutions that reduce costs and enhance efficiency. Long® double-sided insulated gate bipolar transistor (IGBT) cooling systems produced by Dana enable electrified vehicles to achieve consistent operation and long-lasting performance. As OEMs design electrified vehicles that compete with traditional combustion engines, the need for… Read more »
Details of Tesla Model 3 continue to trickle out
As the long-awaited delivery date for Model 3 draws closer, more details of the world’s most anticipated vehicle are slowly coming to light. Production is to start in July, and Elon Musk has said that deliveries will begin in July as well – probably with a ceremonious handing-over over of keys to a handful of… Read more »
New VW subsidiary to manage $2 billion investment in EV infrastructure
Volkswagen has formed a new subsidiary to manage its $2 billion penance for the dirty diesel scandal. The new company, Electrify America, will be based in Reston, Virginia, and Volkswagen Group of America Chief Operating Officer Mark McNabb will serve as its CEO. Electrify America will build and maintain a “high-speed, cross-country” network of over… Read more »
Tesla subsidies amount to a fraction of what the Big Three have received
Tesla has been the target of trolls, misinformation and fake news stories since its founding. Whole web sites are devoted to trumpeting the company’s failings, real and invented. Since the US presidential election, the torrent of tirades has kicked into high gear. The Institute for Energy Research, a think tank funded by oil and coal… Read more »
New supercapacitor has the potential for “astonishingly high” capacity
Supercapacitors, which can be charged rapidly and deliver intense bursts of power, are a hot topic these days. However, current supercapacitors use components made of carbon, which require high temperatures and harsh chemicals to produce. Now researchers at MIT and elsewhere have developed a supercapacitor that uses no conductive carbon, and that could potentially produce… Read more »
MIT researchers discover two forms of lithium dendrite formation
Battery researchers around the world are working on lithium metal electrodes, which have the potential to greatly increase energy density. But the drawback to lithium in this form comes in the form of dendrites, root-like lithium deposits that form on the metal surface and can harm performance and even lead to short circuits. Now a… Read more »
Researchers use nanolithia to improve efficiency and longevity of lithium-air batteries
Lithium-air, or lithium-oxygen, has been touted as the ultimate battery technology, because its theoretical energy density is ten times that of current lithium-ion solutions. However, scientists have struggled to overcome major challenges with the technology. The batteries waste a lot of energy as heat, degrade relatively quickly, and often require extra components to pump oxygen… Read more »
A closer look at wire bonding
Wire bonding technology – widely utilized in the microelectronics and power electronics industries since the 1970s – is finding its way into interesting new applications in the growing EV industry – in particular, battery connections. We’re quite certain that a few EVs are using wire-bonding technology for production battery pack connections, but Charged was unable… Read more »
