Thanks for the links, patb2009. Interesting stuff and proof this idea can work.

Thanks for your comment, patb2009. So it still seems we have quite a range of opinions on this solution, with some of our readers thinking it's not worth the cost and not the most efficient way to supplement the battery, and others thinking it's a great idea.

Thanks for your comment, fm, I always appreciate hearing real-world perspective, especially from someone who has considered the product written about. Although I have to say, this is a new product from Maxwell, so perhaps you checked out the one for heavy-duty trucks. This is a more midrange option and is perhaps more cost effective.

i imagine there is some control electronics in that box, but, a 

Cap has nice characteristics that back up a battery.

 

A battery has good energy storage but doesn't discharge toofast.

 

a Cap has crap energy storage but discharges like a dead short.

 

put in some electronics to make sure it doesn't do anything too strange

and it will be awesome.

@patb2009: How about controlling the heat ? You have to remember that it generates a huge amount of heat and if its not being well managed then the battery might explode

i imagine a supercap can elp balance a battery by providing a outrush current

even when the battery is sick

 

now in the design-news philosophy, i've been reading a bit on iron batteries,

you would think trucks would use iron batteries. especially with a supercap.

From what i understand, it's pretty simple electronics in Maxwell's box. It's the supercaps themselves that are the cost driver. I looked into this product awhile ago, curious to see whether it could replace batteries in a battery-backed solar installation - eliminating the maintenance requirement. I rejected it for now as it's a hideously expensive solution, both in dollars and in volume consumed. These devices have come a long way, and they're now at about 1/10 of the energy density of some batteries, but they're not ready yet for many big-time applications.

Thanks for your comment and perspective, cvandewater. This was certainly not intended to be an advertorial, but you are certainly entitled to your opinion. It seems like there are a lot of differing views from our reader experts on this topic, and it's great to see such a spirited debate. I am sure there are different ways to solve the problem of drained batteries in these types of trucks, and Maxwell's is just one of them.

Thanks for this perspective, tekochip. It sounds like then that the scenario presented by Maxwell with its new product is possible, although I think people have differing opinions about this and there is quite a debate going on. But that's what these comment boards are for! It's interesting to hear the different perspectives.

Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental.
