Re: Battery cooling academic paper

In most cases this isn't an issue. Only for hybrids pushing tiny battery packs to their limits. Heat pipes and PCM all sound quite expensive. I'd want to see a comparison over traditional cooling spreader plates or thin water cooled plates. https://www.ekwb.com/shop/media/wysiwyg/EK-FC1080_GTX_Ti_NP...

Re: 20 x Leaf Cells

So currently I am building a constant power load to test all the cells I have. That way I can get all the cell capacities so people will know what they are buying. Probably best to wait a bit until I have tested all the cells. I have finished making the bare PCB and in the process of loading the com...

Did the sparky check the isolator? I have a gas HWS that is due for replacement. I have a giant ducted revers...

Aggressive cycling of cylindrical cells in Hybrids. Then using heat pipes to cool them. First world problems... Jaguar land rover supplied the cells.

I am working on a constant power load to make cycle testing easier.
Once that is done I should know the capacity of each of the cells.

Re: VF2 SSV Redline - Hybrid EV conversion?

The technology is basically there but no demand means it doesn't exist for aftermarket converters. If you think of something like a Yasa-750 is almost there as a hub motor. Two in the front means an extra 200kW+. But I'd think that would be $50k+ just for the motors and controllers. 5-10kWh of LTO b...

single speed reduction (total reduction of 1:7 or thereabouts).
Normal diffs are like 3.8-4.1 : 1.
Where does the rest of the reduction come from?

Hopefully not the 50 year old box that only did 115Nm when new.

Re: Starting to research vintage Mazda conversion. Help appreciated.

A 6-3/4" DC motor would work but be on the low performance side. An 8"-9" DC motor would be as good or better than original. You "could" think about getting around without the box with a 9" motor and would probably be the cheapest option. There is some noob around here that if he got off his arse a ...

Aim for >200 Nm of torque for most of the operating speed.
60-70s Mazda with 1.5L.
I'd think 200Nm is too much.
You'd bust the box on the first trip.

More like 130-150Nm with the box.
If the gearbox was gone then 350-400Nm.

Re: Disposing of old lithium batteries

Used rechargeable batteries are a hazardous waste and should not be placed in the garbage bin. The fact that they are zero volts or no makes no difference in the end.
