Battery technology remains a major challenge for developers of electric and hybrid-electric vehicles. With a three- to five-year life span, every hour of battery life counts in determining vehicle cost-effectiveness. Moreover, concentrated temperature gradients, indicating heat buildup within a battery module or across a battery pack, can shorten battery life by causing accelerated corrosion, chemical imbalances, and thermal strains on electrode materials. To address these problems, engineers at the Southwest Research Institute (SwRI) Vehicle Systems Research Department use thermal imaging to better understand how the batteries behave under certain conditions, such as experimental fast-charging completed within 20 minutes or at extreme temperatures. The imaging can rapidly and accurately identify energy-wasting hot spots, unpredictable gradients, and transient behaviors. Without thermal imaging, engineers must use thermocouples placed at a discrete number of sites on the batteries to obtain temperature distributions. Not only is this costly, but thermocouples interfere with the taking of sensitive measurements. FAX Elizabeth Douglas at (210) 522-3547.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
