Re: Prelude conversion project - some questions

Hindsight is a wonderful thing - If I'd thought about it, I might have realised that the AC input cables were going to be quite difficult to terminate with so little clearance between the wall and the PCB. Still, they're installed and the radius isn't too tight. One more connector to install and we ...

Hey Matt, yeah I'll take possession of the case if it's in better condition than the one I clearly paid too much for. We can scrap the one I have instead.

Re: Prelude conversion project - some questions

I put a connector on the thermistor bundle wiring and plugged the Arduino in. A friend helped with some code (Quick Median library) which takes 5 samples and chooses the median value for the result. It means a far less spikey sampling (so I'm told). The readings from each thermistor varied by no mor...

Re: Prelude conversion project - some questions

It was a productive weekend, but not as productive as I'd hoped. I genuinely thought we would be driving the Prelude by now, but a few things have held me back. Started off well - got all the HVDC work finished so now the only task is to install the LV wiring. Since I lopped the cables off a bit sho...

Re: HELP PLEASE I think I killed my cells

1.6 V is not good, but if that's the lowest voltage, then I think you might be fine. Charge them at 10 amps - AC or DC that's not much current.

Re: 3 phase outlet, what is suitable for EV charging?

Not sure about the regs around running multiple 3-phase 10 A outlets on a single 16 A 3-pole breaker but the best you can manage is about 7 kW, assuming the vehicle was being charged from all three phases. Otherwise upgrade the wiring to 6 mm2 cable, install some 32 A 3-pole breakers and get the ful...

Re: Prelude conversion project - some questions

I popped the top off the 6.6 kW TC charger, and yep, it's potted like crazy in there, so no repairs will be happening here I suspect. However I could bolt the DC/DC converter to the lid with ease:

Re: Model 3 Pack Size

Pretty sure the pack sizes were ~52 kWh and ~75 kWh.
The long range car has 4416 cells as 96s46p. The cells are about 4.6 Ah each, so that checks out.
The 'standard' range (nobody would ever say short) is 96s31p, giving about 52 kWh.

Re: i-miev degradation in the tropics

Yes, heat will definitely reduce the useful range of a battery - Arrhenius equation applies. For every 10 degrees Celsius the reaction rates will double, and that includes the bad chemical reactions which reduce the capacity of the battery. An EV without an active thermal management system in the tr...

Well the decision to make it a shorter range, lower voltage car was made. Sad, but I'll feel much better knowing that there's nothing rubbing of chaffing against something it shouldn't. It will make for a less powerful car too, with peak current around 200 A and 270 V nominal, it's a mere 55 kW mach...
