Slideshow: Pack Expo Packs 'Em In
11/8/2012

< Previous   Image 2 of 12      Next >

Kollmorgen showed off Virginia Tech's Battery-Operated Land Transportation (BOLT) all-electric motorcycle. The bike is powered by Kollmorgen's AKM 74 AC permanent magnet motor and an 80V Gen6 drive. The VT Bolt hits a top speed of more than 100mph using a 7.5kWh battery.

Packaging engineers must be a quiet bunch, bobjengr. In popular culture, there's nary a mention of packaging engineers. You wouldn't know they exist if there were no trade journals. Yet, here we have 43,000 engineers showing up for Pack Expo.

Chuck--This looks like a terrific show.  43,000 + has to exceed their expectations.  In just about every place I have worked over the years, packaging has been somewhat of an afterthought.   At GE Appliances (Roper Corporation) we did have a packaging engineer but that was only one of his responsibilities.  In the appliance industry a good number of the DOA problems have been due to transportation issues and not relegated to product design.  Great post and thank you for showing it.

Well, I suppose a little extra detail never hurts, Ann.

I should have been clearer in stating my question: I know there are tradeoffs in general, but wondered what they were with this specific battery. OTOH, glad you replied in detail because now I know more, especially about top speeds and how to get there. Thanks!

I don't know what the range of the motorcycle is either, Ann. As to your question about the tradeoff...yes, there is absolutely a tradeoff between power and energy. In some cases, one is realized at the expense of the other. By boosting a battery's current collector and reducing the amount of active material, EV designers can provide the amps needed for high torque and fast launch. But when they do that, they diminish the battery's energy density and, therefore, its ability to drive longer distances. Having said that, I don't think that's the case here. Electric motorcycles have gone much faster than the BOLT. An electric motorcycle called the KillaCycle hit a speed of 168 mph four years ago, and I'm quite sure the figure is much higher now. I have little doubt that en electric motorcycle could hit speeds in excess of 200 mph (if one hasn't already) by making the battery changes I described above. I don't know about this specific battery, however, having only seen it at the Kollmorgen booth at Pack Expo.

Chuck, my question was regarding whether there's a tradeoff between acceleration/top speed--needed in a racing bike like this one-- and the range. I spent some time Googling to find out what the range is, without success. Do you know?

I agree, naperlou. It is like a robotics show. Robotics form the foundation for a lot of the packaging technology.

You're right, Ann. The energy density is more a measure of a vehicle's range. The power density is more about its ability to accelerate. For proof, check out our earlier article about EV drag racing.

The all-electric motorcycle is pretty impressive: 100 mph on a 7.5kWh battery? I wonder how long the battery lasts.

Yes, Chuck, I could see the size of the show from your last shot, and I would guess that was just a portion of the show.

Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
