Excellent article. I have a client working towards providing a device that will use the very same start-stop process you describe in you post. I agree completely in that this technology will become extremely important as manufacturers strive to meet the fuel requirements mandated by the "FED". It's good to know my client is basically on the same page as others. Again, excellent post.
Yep... A123 gets more than a quarter of a BILLION Government dollars, but just can't make it work. No problem - the Chinese swoop in and buy the whole shebang - AND at fire sale prices. Smart move, Zenmasters! China links A123 to their abundant and highly controlled access to the prime raw material - Chinese controlled Lithium. A nice economy of piracy, IMO. Score US 0 / China 1
Meanwhile, in a tacit admission that current EV designs are market failures, A123 debuts their "new line of batteries" tipping their hat to the start/stop designs, which might actually make a modicum of engineering sense. This announcement conveniently happens even as GM announces they are going strongly towards micro-hybrids! Hmmm... GM + A123 + microhybrids. That's an even less than tacit admission that the EV scam is a failure as a business model, no matter what its tree hugging merits might be. If GM is ready to write off the volt, you can figure that micro-hybrids are going to carry the next half decade.
The next move? Well, for one, expect more climate change hysteria as the juggernaut of "oops..we found more oil" announcements both in the US and Australia impeach the main candidate for pure EV ascendancy. That will make it even more incumbent upon EV acolytes to fall back to their secondary strategy of climate change hysteria, e.g. "sure we have lots of oil, but we can't USE it anymore!"
A123 is a great battery line, I just wish they were lower cost.
Start/stop is just a short term thing, 5-8 yrs at most, but a market is a market. And unless battery compnies find some markets, they are doomed.
I'd not use a 12vdc battery here with the 48vdc one as just more cost, complication especially since you need a DC to DC anyway to keep the 12v battery charged!!
The most important thing is these/lithium batteries can be left not fully charged, in fact they like it, unlike lead acid which needs charging till full or it dies.
But if one were to plug their SS battery in at night a couple times./wk, lead would do this for much less.
Another is for the same price, putting the starter, alternator in the flywheel saves so much weight, cost, parts plus can be used to boost power I can't figure out why they don't do it that way for another 5% economy boost for less money.
Interesting discussion here and thrilled to know awareness about Micro-Hybrids..We have developed our own Micr-Hybrid device that can be installed in any car as an off the shelf product..We have tested our system on 7-8 year old cars so as to know impact on old batteries & starter motors and result are just astonishing..we have got 15-20% fuel saving in those cars without hampering any of the existing components..presently we are only offeting auto stop/start and regenerative breaking woulb be introduced later as it requires Li batteris as mentioned in the article.
we are very small gourp of youngsters and don't have huge budget for marketing & promotions so looking for suitable tie-ups worldwide..kindly get in touch to discuss our proposal in detail..
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
