2x A123 pouch cells

I have two unused A123 pouch cells I bought to experiment with. I've never connected them to anything or charged them. Checked the voltage today and they're both still rock steady at 3.325v. The pictures make them look deformed. They're actually flat and solid. I'm clearing out a bunch of stuff in p...

ELMOFO Electric Radical - Debut Race - SuperSports

Awesome stuff! Very excited to see it performing so well. Once the technical gremlins are worked it, it'll be a force to be reckoned with. Just don't pull an Audi and get EVs banned from the series by being too fast ;-)

Posted a link to the PDF datasheet I got of the motor before the rewind to my for-sale post so as to not clutter this thread too much.

Is the car still under warranty? Something like that may be covered by a recall as well, if it's a common problem. Probably worth a trip to the dealer.

For Sale: "The Beast" - 220 kVA VFD $3000

The stator is hardwired in Delta on my motor. The cables in the photo go directly to the windings, no junctions. Jon could rewire it to star though, I'm told. The motor in the 300zx had 6 cables brought out, but I've connected it in delta as well. I would be willing to swap motors if you needed to b...

EOI: Catavolt custom induction motor and core

Higher voltage means full torque to a higher speed. With my pack, I'm expecting full torque to around 6500rpm or so. A lower voltage pack would produce the same torque, but to a lower RPM. The setup in the 300zx is aimed at performance.

EOI: Catavolt custom induction motor and core

The trick to using this motor would be finding an appropriate controller. The Tritium should do fine. I'm using an identical motor in my 300zx conversion and I expect the performance to be quite good. It will use a 376v pack and my on controller (one-off).

Could anyone help diagnose my soliton's issue?

Hmm, the pack is sitting at 149V though. They got me to check all the cells,too, they are all sitting at 3.3v, tho I don't have a load tester. At a guess the lead-acid pack might have varied between 156V fully discharged and 182V fully charged. Your current pack voltage might be a bit low, it would...

Twin 9 inch vs twin 11 inch

The drag cars have enough trouble putting down the torque from the twin 9" motors! Twin 11" ones would be nuts if you had the controllers and batteries to feed them. Racers always find a way though.

Maybe it's a power/weight ratio thing?

Increase in the fuel excise.

There seems to be a lot of fear that more EVs on the road would result in more regulation and taxation of EVs in a manner that would be unpleasant or otherwise destructive. I'm genuinely curious, has anything like this happened (yet) in countries with high uptake of EVs? Norway, US, Germany, UK? Or ...

I got this motor from Jon a few years back in preparation for my BMW conversion. A functionally identical motor (also from Jon) is going in the 300zx project. I'm going to be moving to the US in a few months, so am not likely to get to use this motor for the purpose I had it made. My employer is cov...

Thanks, BigMouse. As a point of interest, does a Peukert coefficient for these cells happen to "pop out of the maths"? [ Edit: I mean out of other work you are doing; obviously it won't come from just voltage sag with current. ] Not from these results, but I did do the tests required to get those r...

I've been doing a bunch of testing on a CA40 cell as part of my thesis lately and finished today. Most of the tests were simulated driving cycles with the aim of developing a SoC estimation algorithm. Today I did my final test, and thought I'd do a high-current ramp on it just to see what the cell i...

Wow, that oscillation is pretty severe. No wonder you were having issues tuning the response of your controller. The springyness caused by that is huge. I'm going (semi) solid mounts on the 300zx. Polyurethane spacers pretty much, with a bolt going all the way through. I'm hoping it doesn't make too...
