Re: Vectrix VX1 Lithium for sale

Is there a build thread anywhere for the upgrade to lithium battery power? What range does it have now? The fact it is in the Perth area is an issue for me, I don't trust it being transported over without everyone in the yard taking it for a spin each leg of the trip over and it getting scratched or...

Re: Prelude conversion project - some questions

Possibly a water heat exchanger, https://freezetec.com.au/products/marine-refrigeration/seawater-cooled-condensers/ water can carry 3 times the thermal energy of air, so the same area water radiator as the air conditioner condenser radiator would effectively equal an air conditioner air heat exchang...

Re: Ev parts

Thank you Matt. Should have realised it would be a brush type motor and I have no interest in those. Price was certainly good for anyone who was after that sort of thing.

Re: Ev parts

Thank you Brendon, much appreciated. The Fb1-4001 has a max voltage of 144vdc, is that nominal as in 45 cells @ 3.2v nom. or a ceiling upper voltage limit? Could it be used with another controller at say 273.6vdc max, nom. 243v, 76 cells @ 3.2v nom? Maximum RPM would be insane and useless really, bu...

Re: Prelude conversion project - some questions

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. It was new once ;) But yeah, this one has welded several times now. I wouldn't mind getting one of these GV350 units, but it looks like the...

Re: No more i-miev's

Hadn't thought about that angle Matt, yet another reason to go for the bigger battery pack, the resale value after 5 yrs or 7 yrs because the EV still has an excellent range capability where the minimum size battery pack would show a serious loss of range by the 5 yr or 7 yr mark.

Re: Prelude conversion project - some questions

I can investigate that tomorrow, if I remember that is :lol: but a momentary pulse of 24v to pull it in with a 12v continuous supply would verify if that was the case. I still have quite a few 24v Gigavacs without the aux wires that I could still use if that is the case. I went back to 12v supply fo...

Re: No more i-miev's

Lets say you drive 300,000km before a battery change in 10 years on the standard pack. Now lets say you still drive 300,000km in the 10 years but you pay an extra $10,000 for a bigger pack. Or perhaps you still drive 300,000km in the 10 years but pay an extra $25,000 for a super sized pack. Then ma...

Re: Prelude conversion project - some questions

Well in the case of the drive contactor, I might swap it out for one of these: https://www.gigavac.com/sites/default/files/catalog/spec_sheet/gv200.pdf The auxiliary contacts are good for indicating it's on (or stuck). I didn't wire up the auxiliary contacts on the master contactor, mainly because ...

Brother in law does exactly that on the side of the Huon Valley overlooking the river, but he only requires a20 mtr fall.

Storing energy

The way we normally view storing solar voltaic energy is in a battery because this is a bit like cash in the wallet, it can be used for a number of different purposes depending on just where it needs to be used. But energy can be stored for specific uses as well, and maybe cheaper than batteries. Wi...

Re: Off-grid solar diagram / ideas

The solar array I had for my Prius was 290vdc open circuit, so no controller required because the 76 cell pack comes out at 3.8v per cell at the maximum open circuit voltage the solar array could provide, but of course there is no current at that voltage so it never got there. The 15 panels were at ...

reviving an old thread here, but what blocking diodes do you guys use? on my setup I have 4s5p 175W 36Vmp, 5.5Amp setup. I had a 10A10 blocking diode on each string as I was direct connecting to a 144v nominal battery 10A10 diodes are normal silicon units, so 0.7v or 0.8v drop. At 5A, they're getti...

Re: Making home EV ready

So, if the inverter remained isolated and remained a floating system, line 1 and line 2 rather than neutral and positive, then the AC would not be seen on the vehicle negative side so it wouldn't trip the leakage to the chassis problem. If an RVD rather than an RCD was used on the 240vac output the ...
