  • Tesla Model S battery pack, from U.S. patent 8286743 for Vehicle Battery Pack Ballistic Shield

    Unless your name is Brinks, you rarely hear the words "armor" and "car" mentioned in the same sentence. But two recent widely-publicized fires in the Tesla Model S electric car have put the spotlight on how its battery pack is protected from severe impacts underneath the car. MORE: Tesla Fires: What We Know, And What We Need To Find Out Both fires were caused by high-speed collisions with road debris, which apparently struck the underside of the cars, where the battery is located under the floorpan. (A third fire in Mexico came after such a violent collision that a gasoline car may well have...

  • Lithium-ion battery pack for 2014 Chevrolet Spark EV electric car

    Electronic sensors don't occupy a huge amount of space in electric car battery packs, but conversely, making sensors smaller could make the packs themselves much more compact. According to the MIT Technology Review, the U.S. government’s Advanced Research Projects Agency for Energy (ARPA-E) says smaller sensors monitoring individual cells in a battery pack could reduce pack size by 20-30 percent. It's all about monitoring. Tiny sensors could be used to assess the state of every cell, relaying more detailed data to the car's control systems. As a result of this, automakers could safely...

  • Tesla Motors CEO Elon Musk at Motor Trend 'Car of the Year' ceremony in New York City, Nov 2012

    Reporters interview CEOs all the time, but it's rare for those CEOs to end interviews abruptly. Which is what makes an article in Barron's about Tesla Motors [NSDQ:TSLA] and its current high stock price so entertaining. In "Recharge Now!", author Bill Alpert opens with a comparison between Tesla CEO Elon Musk and Iron Man comic-book hero Tony Stark. He summarizes the rave reviews received by the Tesla Model S all-electric luxury sport sedan and notes, accurately, that Tesla stock was propelled to its current heights on the basis of one profitable quarter and a classic short squeeze. In a...

  • Historical Prices & Specific Energy Trends for Li-Ion Batteries (Duke University, 2009)

    Did your parents ever tell you, "Slow and steady wins the race"? It can be annoying to hear as a child, but often it's true--and in the case of electric car batteries, it's how they'll get less expensive. As a new posting from the Washington Post's Wonkblog points out, there is no Moore's Law for batteries. That's the law underlying the rapid improvement of consumer electronics like mobile phones and computers, which says the number of transistors in a microelectronic device roughly doubles every 18 months. Run that rate over many years, and you get order-of-magnitude improvements in...
