Imagine a day when charging is as simple as pulling into a parking space. No cords to untangle or trip over, nothing to get your hands and pants dirty and nothing to wrap up when you're already late leaving for work. Just park your car, and forget it. That's the beauty of charging wirelessly through electromagnetic induction. It's still a nascent technology, though - as least when it comes to electric vehicles - and not without its problems.
If anyone knows of the Fraunhofer Institute at all, it's usually for their role in creating the MPEG-1 Layer 3 digital audio format. That would be the bane of the music industry more commonly referred to as MP3. The researchers at Fraunhofer work in lots of different areas, including battery technology. With thermal runaway being the primary safety concern with lithium ion batteries, Fraunhofer has been looking at the causes and possible solutions. Batteries have a liquid electrolyte between the
Traditional metal sheet forming allows volume production of automotive body parts such as doors and roofs via a process known as deep drawing. The metal spools off a huge roll to be pressed into a corresponding mold by a three-dimensional die. High-strength steel, such as high-alloy hardenable steel or high-nickel maraging steel, is starting to take over from conventional steel though as auto makers look to reduce vehicle weight and boost fuel economy without compromising safety or performance.
