Re: Prelude conversion project - some questions
All I know is it used a nickel sulfamate solution, so electrolysis was involved I think.

Re: Prelude conversion project - some questions
Oh there may well be one, but I was fast running out of time (still am). Plus I have no experience with nickel plated copper and how it welds.

Re: Prelude conversion project - some questions
Copper is highly reflective, so it needs to be a fibre laser so the optics don't get burned out. They can't cut nickel for this reason either. Waterjet cutting has a kerf of about 0.5 mm which is probably OK for this stuff, but the sheer number of holes and cuts made it expensive and slow. I'd block...

top side welded.jpg Module glued up.jpg Okay, so the first module is more or less done. Some key observations about this battery building technique. 1. It's painfully slow, but only because I have a small welder with tiny electrodes. I feel it would be faster if I only needed to zap each tab once o...

Re: Prelude conversion project - some questions
There's a lot of learning as I go along too. I finished the other side of this module in a day, but yeah its a huge job. If the nickel stuck to the plated aluminium like I want it to I could have done all 4 by now.
In future I'll use 21700 cells, as they're 30% less work.

Re: Electric Maserati
Dave I tried paralleled DC motors on my first electric motorbike and it was a PITA. One motor would always end up doing the work. It's far better if you put them in series and let them share current equally, even if that means more volts on the battery pack.

Re: Prelude conversion project - some questions
Yeah, but I'm trying to get the car out of the garage by the end of February. No good ordering stuff now given Chinese New Year. I worked out I can do a busplate (46 tabs) in 40 mins. So that's 8 days work of 8 hours a day. With four welders and four people, I should be able to knock that down to ab...

Re: openEVSE single phase 32A charger use at home and away
I usually find the car side lead plenty long enough. Just arrange something to take the strain like a string to hang it from the socket or something.

Spotwelding party! BYO spot welder.
Okay so this is a huge job. It's taking me about a minute to weld each tab to the busbar, and maybe 10 seconds to weld it to the cell top. Either way, there's about 2 weeks work assuming no sleep or work... :? So I'm putting the call out to anyone who has a welder to come and help me do this. I want...

It doesn't stick out like bollocks when it's on the wall. Wire up L1 and neutral (and protective earth) on the socket and plug and you should ...

Re: $6000 EV
For a half decent, 150 km range EV? About $40k.
For a bare bones, DC, good enough? About $20k.
Li-ion batteries haven't gotten cheaper, but they have gotten better. What used to take up a whole boot and then some for 100 km around town now takes up half as much space.

Second module ready for spot-welding.

I hope it finds a good home, Rob. The converter must have an eye for detail, and no half-arsing. When an old/classic car is converted it needs to look the goods - it's already a contentious issue converting a classic to EV, so having it look a bit 'howyagoin' only adds to the consternation.
