Re: Prelude conversion project - some questions

Yeah trying to avoid that. I don't like the idea of having batteries anywhere inside the cabin because a) they might dislodge in a crash and become projectiles, and b) in the unlikely event of a fire, the cabin becomes smoke-filled very quickly. I built the modules with the preferred layout in mind,...

Could you ditch the rear seat entirely and keep the 4ws, make mounting your cell modules easier too.
Unfortunately no - even with the rear seat gone, it won't fit in the remaining space. It's just in a really inconvenient location :/

The Prelude Conversion begins!

Technically it began when we started sourcing parts, but it's for reals now that the vehicle is immobilised. I started by weighing the car using a fairly reliable method - two bathroom scales to evenly share the weight of a single corner of the car, while the other three corners were supported with ...

I'm going to pick up a pair of 180 kg scales this morning. After all, we could use a set in the house :)

Re: Prelude conversion project - some questions

It begins in earnest: Bonnet off.jpg We drained the fuel tank, but the shed happened to have half a dozen seasoned EV drivers who complained bitterly about the smell... We shan't get too carried away as we still need to weigh the car front and rear. I hope to get some cheap spring-balance bathroom s...

Re: ICE alternator current display/logging

So you want to be able to look at currents as you drive? A bit like the old ammeters you still see on vintage tractors and the like.

Re: Prelude conversion project - some questions

Nice Hoist - I'm there 8-) What about the BMS? Do you have to remove the lid of the battery modules to fit that? Yeah I'll mount the BMS inside the modules and run the signal / CAN Bus wiring from one module to the next, probably via the sides but I'll have to wait and see how it all fits together ...

Re: Prelude conversion project - some questions

Is the potting compound only on the bottom of the cells? Correct. The bottom face of the cell stack represents about 20% of the total surface area, and it's all in the plane of the electrodes, so thermal conductivity is at it's highest. Screenshot from a video I'm preparing: potting screenshot.JPG

Re: Prelude conversion project - some questions

It's polycarbonate which is tougher than perspex. The screws are also glued in place by virtue of the seal it goes through. I reckon they will be okay.

Re: Prelude conversion project - some questions

I should add this was based on a measured DC IR of 100 mOhms per cell, which is probably higher than it really is. But not a lot higher. It's a used pack, so the DCIR has no doubt increased from new (which is supposed to be 60 mOhm).

Re: Prelude conversion project - some questions

I've not yet set the modules up for testing, but I will have several tests to do by the weekend. The one module have already built is to be the 'spare' module, and it's just as well because the thermal epoxy doesn't have the sort of coverage I'd like it to have. It's probably 90 % as good as it need...
