I even logged off, idling, and cruising system voltages for several weeks - only to be bored with monotonous readings. My alternator spits out 14.4-14.6v and the resting voltage of the battery before starting would be 13.5-13.8. This is a 4 series pack. I have NO protection circuitry. Been operating since the new year with ambient temps from -1F to 85F. I'd be content with a 4s2p A123 pack at a fraction of the volume I currently use. <br /><br />Still waiting to see the impending doom...Nabil Hankehttps://www.blogger.com/profile/17576270527985289857noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-3027549631762820642012-03-19T15:17:48.544-05:002012-03-19T15:17:48.544-05:00Tom,

Running the lights and accessory loads isn't really in issue. A little on-board intelligence to prevent overcharge and overdischarge would make a nicely featured starting battery product for the racing community. You probably wouldn't need to charge it at all during the race; maybe a simple diode might be enough to prevent overcharge. The discharge side is a little trickier, should, say the race car throw an alternator belt and suck the battery flat. <br /><br />The promise of a 4-cell, 6lb battery the size of an air filter that lasts 12 seasons would be quite something. An 8-cell 10 pounder that would start almost any racing engine would be equally attractive, even at more than a few hundred dollars. <br /><br />I've been out of it for a while, but I know the "carbon fiber" AGM racing batteries available are in the 6-20lb range, but they have tiny capacities- far less than the 18.5+Ah of an A123 pouch. The go for $150-$500, too. I've heard that some guys were more recently paying $1000 or so for special "lithium" batteries, but I've neither seen one, nor looked into it. They're not common.<br /><br />There's a really good small (garage) business opportunity here for someone willing to figure out the minimal protection circuits needed, and continue the packaging work based on Jack's research. The good news is you could have a profitable product at, say, $399 for a 4-cell or $599 for a 6-cell unit, and sell repackaged chargers, too. <br /><br />The best news is that if it works, such a battery would sell like hotcakes in the racing community, where word of a performance/weight advantage like this spreads very quickly. <br /><br />Somebody is going to be trying this in short order...Tom Alvaryhttps://www.blogger.com/profile/13138074813335115689noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-69860212305451842222012-03-19T07:15:29.853-05:002012-03-19T07:15:29.853-05:00If an error is flagged because an injector is miss...If an error is flagged because an injector is missing.

I'd advocate trying solutions based on a series chain since the tabbed pouch format lends itself well to that. it requires no aluminium blocks or bolts thus can be ultralight.<br /><br />if you are considering 12V batteries for cars, I'd advocate a single chain of 20Ah. you basically don't need more for a starter battery. I don't believe in an aux battery for an EV but if you want I'd also make that 20Ah max or even much less. like 4 2.3Ah cells in series. it needs neither power nor capacity. it's worth thinking about how iron phosphate works with a car alternator recharging policy. it might not live long.<br /><br />you talked about the prius C, that's not a plugin though. no biggie.<br /><br />if you need to convert hz to voltage then an arduino can readily do that with an RC filter on the pwm output to function as a DA<br /><br />the camera focus was hunting a bit during the battery cast segment.

Want more strength? simply glue on something stiff to the sides.<br /><br />The job of the insulating spacers with their four 6mm steel threaded bars clamp the tabs solid. Same as Jacks flatenum; movement does not happen. If you are bothered, glue gun.<br /><br />I must reiterate. The cell sides click themselves to the box inside. It becomes a sold load sharing block on its own!<br /><br />The sum weight of the materials makes it suitable for aircraft work and the cost is very low. I've simply dumped the idea of using thermo set plastics and/or silicon adhesives now.<br /><br />If I find a suitable manf'r for plastic spacers (Dan) and source some reasonable metal for the hard clamp/battery connectors (Dan)... Plus (Dans) special knife: It's a fast assembly and fully self configurable kit!<br /><br />However, I do suggest not making the batteries too big because of the sheer weight they amount to. My 29 cell pack must weigh 16Kg or 35 lb!!<br /><br />Imagine lugging Dan's 100lb+ battery cartoon drawing with no hoist lugs ;)Andyjhttps://www.blogger.com/profile/11910687437796998340noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-5213102624769234602012-03-18T00:08:16.099-05:002012-03-18T00:08:16.099-05:00I'm intrigued by the corex idea, but not sold ...I'm intrigued by the corex idea, but not sold on the notion that it will adequately arrest movement of the tabs. <br /><br />Jack, a thought occured to me on the whole casting conundrum. I'm liking the idea of having the bulk of the volume filled with cells of gas rather than solids, that is, foam. But I'd like to see more solid skinning around the whole mess. What I propose is a three step process. <br /><br />First, cast the harder solid resin/plastic to be about 3mm thick by using an outer and inner form. Then remove the inner form leaving a five sided 3mm walled box. Drop the cells into it and foam fill with a determined amount to leave the tabs outside the foam. Maybe use a less aggressive color than green next time ;). Then top it off with the harder material. I would also suggest putting alignment holes in a sheet of uhmw to bolt the blocks to; and give it a fill hole or two. This would get all the terminals coplanar and to regular placement. Another advantage would be that it would seal the top surface from getting covered by resin.

That was going to be my very advice to you!<br /><br />Hey, I've made a first off 96v single string battery out of A123's with 4mm Correx and a lot of 100m wide x 160mm long x 1/8" thick insulators bound together (threaded through) with 4 off 250mm long x 6mm threaded bar.<br /><br />My method lends itself very well to in-battery parallelism and any width lengths. The only special tool required is a piece of 1/8" insulator with a blade each side to cut out every other Correx channel for the cells to slip into. The cells folded edges clip into the channel burrs so avoids the need to glue. They self retain the box shape!!<br /><br />Dan is selling the knives at 2 Euro's apiece (+P&P&taxes). It will save you hours messing with a plain blade.<br /><br />Next he is going to get a plastics firm to cut out the insulators en-masse for easy assembly.<br /><br />Please notify Dan on here via EVTV which are holding this special offer for the regular blog readers.Andyjhttps://www.blogger.com/profile/11910687437796998340noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-1815264649694383432012-03-17T13:29:37.230-05:002012-03-17T13:29:37.230-05:00something could be done about the EV components si...something could be done about the EV components situation, Jack. you could aggressively promote development of new widely suitable components.<br />maybe be ready for EVCCON2. maybe even be in cars by EVVCON2.<br />either jointly with existing providers or find a few new guys. maybe semi open source such that all players can do their own take on it.Dan Frederiksenhttps://www.blogger.com/profile/00506872737104553923noreply@blogger.comtag:blogger.com,1999:blog-6676835811534572362.post-71505057837168904272012-03-16T17:21:53.357-05:002012-03-16T17:21:53.357-05:00Fascinating about Thomas Davenport.
