I have 42 Saft NiFE Nickel cadmium batteries. SBL16-2 Located in Perth (kelmscott), Western Australia Each one is made up of 2x 1.2v 16ah cells. So it's 84 cells total that makes up 100.8v nominal. Ie 1.6Kwh of energy. I got them from a decommissioned backup power system. I don't think they've done ...

A Google shows Gvm is 1565kg People and luggage is 81.6kg per seat 81.6kg x 4 seats = 326.4 1565kg - 326.4kg = 1238.6kg Standard weight is 1060kg - 1340kg depending on model You got 1100kg when you weighed it and presumably you are also going to ditch the spare tyre now. Looks like you have some rea...

Ute chop?

Leafs have chademo which is bi directional. Teslas don't have chademo so I wouldn't expect it any time soon. Also Elon Musk said a few years back that teslas won't have car to grid. I'd guess the argument is he wants to sell you a power wall

Oooo, that's an interesting idea.

My wife asked "how much does the government actually spend on the roads?" It turns out the budget allows for about $5b for infrastructure. And 80% of that goes to roads. But I'll be generous and say the whole lot gets spent on the roads. That's still only a fifth of the $27b excise is spent on roads...

I doubt it would happen but we could make up the lost revenue by not subsidising the fossil industry. A quick Google says the fuel excise brings in roughly $27b and the government subsidises the fossil industry with roughly $29b. So leave the excise as is and let it dwindle and slowly choke off foss...

You should move the thermistor to the heat exchanger if you can as well, that way the compressor won't cut out because the evap is too cold. Or at least make it less sensitive with a resistor or something. Also, perhaps you could put something between the expansion sensor and the evaporator outlet p...

I've come a across that ad before and thought it was a good idea. They're not entirely correct in the training as I've done EV training, here in Perth even. But there's also better /more in depth courses available over East. I guess I should put in a shameless plug for my work... Autospark Rockingha...

The biggest flaw I see is the sides of the tray. Its not exactly work friendly so I think it'll lose out on a lot of fleet/commercial customers and people who actually use their ute as a ute. Also people don't like change, this looks different... Also also, if the body panels are so tough how's it g...

Re: Cybertruck - the fanbois will eat it up. Everyone else will buy a Rivian.

I'm not so sure, Rivian would have to sharpen their pencils a lot before they sell them. The tesla starts at $40,000usd and works up to $70k, the rivian is meant to start from $70,000usd

For those interested here's the tesla live stream (starts at midday Perth time)

It probably could be cheaper but if people are willing to pay $40k then that's what hyundai will sell it for...
Also none of the Toyotas have a plug...

There's so much to unpack there, some good ideas/points and some real marketing crap/cherry picked data.
I don't even know where to begin....

Oof. Pretty good markup on some of those accessories.
290€ for a set of caster wheels for example

Very impressive that's quite a bit of a drive.
Im getting the feeling that you are never going to give the car up but. There will always be another test...

The aircon will be working it's guts out to cool the water in the heat exchanger circuit but once that heat is gone hopefully there won't be too much heat being added from the cells. Remember that aircon condenser was designed to shed all the heat that the cabin gets on a summers day, along with ori...

Well, when a condenser absorbs too much heat we run a garden hose over it, so yeah you can build the first EV with water injection

But at some point you will need to dump the heat into the air and you'll just need a radiator for the water/refrigerant condenser.

Is there anything wrong with putting them in series as I'd originally intended, and just letting it do it's thing? I mean, worst case scenario it just doesn't get very cool. But even that is better than nothing. I just think there's more control with what heat you are absorbing when you can lock ou...

As I said the other day, I would add a tx valve to the heat exchanger and run it in parallel with the original evaporator. All you need then is 2 Tee pieces and possibly a lock off solenoid or 2 to isolate either half of the system when it's not needed so you aren't absorbing heat you don't need to....

When the sales guy took me for a spin before handing over the keys, the ICE kicked in at pretty low speed on a near full battery when he floored it, I assume this was series mode? where the ICE/generator is supplying extra current capacity but no direct tractive effort - I assume this is because th...

a smart pre-charger that only closes the master contactor when the voltage gets within a pre-determined level would also prevent welding situations where say the dc-dc is drawing more than normal on start up. Fixed time pre-charging doesn't guarantee pre-charge unless everything is okay I had a pro...

Is it a new contactor or old or did you get the upgraded gigavac already? My experience is if contacts weld once they'll be very prone to weld again and again.
