Great post Charles. Very interesting. I certainly feel the way to accomplish a lesser replacement cost for the battery package is a series of batteries electrically connected instead on one monolithic device that must be completely replaced. (I am assuming lower replacement cost is the basic intent of the flat battery package.) Agreed, handling due to the lower CG is definite benefit but I have to think cost was the driving factor vs. overall performance. Do you have any specifications on the device itself? I would love to know more. Also, do companies like TESLA patent their innovative components and assemblies and does this battery pack have patent protection?
Tool_maker: You're criticism is on the mark. I'm the reporter, interviewer and camera man on these videos, and I wish I had done better. I'm still learning, but as you probably noticed in the beginning, I was having some trouble getting the camera to focus properly on the car chassis. A little more practice is needed.
Did anyone else find it curious that although the subject of the video was the battery, the overwhelming bulk of the video was the very attractive young woman's face? If this was shot at a car show the battery was there for anyone to see and presumably photograph, but we got only a momentary view of some flat white object that is/was supposed to represent the battery. What was the point of a video? Just curious.
I think we'll get more information some time this summer, Bob. The flat pack is an intriguing idea. The 18650-type batteries provide a lot of design flexibility that the Chevy Volt designers didn't have.
Always very interested in the technical details of 'things' (I guess it is just my 'inner engineer' coming out). I would love to see a lot more on the design of the battery pack for the Tesla S roadster. Lots of questions but not many answers! Of course, all of that detail might be propriatary information but I can hope!
Earlier this year paralyzed IndyCar drive Sam Schmidt did the seemingly impossible -- opening the qualifying rounds at Indy by driving a modified Corvette C7 Stingray around the Indianapolis Motor Speedway.
Wearables are changing the way we see ourselves. With onboard sensors that have access to our bodies, we are starting to know our physical selves like never before, quantifying our activity, our heart rate, breathing, and even our muscle effort.
Last week, the bill for reforming chemical regulation, the TSCA Modernization Act of 2015, passed the House. If it or a similar bill becomes law, the effects on cost and availability of adhesives and plastics incorporating these substances are not yet clear.
