Looking for tester for new lightweight battery

[tonytieger]

Hi all,

My first post here, this is Tony from Voltphreaks. We've developed a lightweight battery for alternatorless applications, and are looking for someone on here to potentially test it for any mileage gains (the battery itself doesn't need testing, this is only testing for mileage gains). Please PM me if you are interested, you would need to be able to measure mileage before and after, and be fairly knowledgable about batteries in general, thanks! - Tony

Hi Tony -

I'd be interested in finding out more, and possibly testing. I've been doing alternatorless driving for three years, off and on (mostly in the summer, when electrical loads are lower, and PbA capacity is better).

See: Plug-in Blackfly: going alternator optional nets +10% mpg - MetroMPG.com

And: Test: Alternator vs. no alternator = 10% gain @ 70 km/h - Fuel Economy, Hypermiling, EcoModding News and Forum - EcoModder.com

I was thinking about an "ideal" battery recently, actually. It would have a nominal voltage of around 13.5-14v - approximately where the car's electronics are designed to run when the alternator is on.

With the alternator disabled, my car runs at between approximately 12.3v - 11.5v under load, which really isn't ideal.

I'm ScanGauge and MPGuino equipped (for measuring fuel consumption), and reasonably knowledgeable about batteries (built/own an EV conversion - PbA).

Let Darin do it, he's the pioneer of alternatorless driving,

Hi Darin,

Wow you have experience in this. Sent you a PM! - Tony

Agreed.

Darin and AndrewJ are the ones who should get first dibs on testing these batteries. They have put far more than batteries on the line in the name of science, and mileage!

Are they VERY Deep cycle, or some type of new construction? Similar to Optima batteries? Please give us some more information on these prototype batteries! How many people are you looking for for testing?

I look forward to the results from these batteries. Good luck!

Edit: I just checked out the site! See it here Those are some expensive Lithium Batteries guys...

[Daox]

Mmmmm, lithium! *excited*

It would be great to see Darin have a go at this.

I agree, Let Darin and AndrewJ do your testing, it will be worth it.

Contacting Darin tonight, yes these are lithium batteries, capable of 2000+ deep cycles, possibly much more with reduced capacity! These are the future of battery technology, currently expensive, though.

tonytieger, who is your battery (cell) supplier?

[Blue Bomber Man]

Quick question maybe difficult answer: I am designing my own car over the next year, could you possibly hook me up with some specs for a electric car battery pack system?

Reqs:
10kwh
120V-244V (havent decided specifically on voltage, depends on the motor and other equipment that I will have to spec out)
would require its own BMS

Would like to know:
Cost
gravimetric energy density
volumetric energy density
number of cycles (needs to be 1000+ to be considered)

Errr, I guess its not a quick question, but it would be great to hear back on this. My email is werblowb@gmail.com if you do not wish to discuss this here

Thanks!
