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 ...

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...

If the inverter was not actually in the vehicle but rather plugged into an Anderson plug connected to the battery with a switching relay that isolated either the Anderson plug via a pr of contactors or the Ev's contactors if the...

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 ...

Re: Making home EV ready

More thinking on this topic. Why would AC be seen on the DC side? It must pass through a DC to DC converter before it is fed into the inverter itself to make the AC wave form, so wouldn't that block any AC waveform. I can understand DC ripple being seen on the DC side, but if the wave form doesn't c...

Re: 4kVA Inverter for 230VAC off a 350VDC battery?

More thoughts on this inverter. If the 48vdc battery was also used, wouldn't that keep the caps charged because it would be powering the inverter when the EV wasn't plugged in?

Re: 4kVA Inverter for 230VAC off a 350VDC battery?

Thanks Matt, makes sense that the solar would gradually charge the caps till the desired voltage was reached and then the system would turn on. if this isn't part of the inverter design then it would need to be added for using an EV battery to power the inverter. I know with the 48v MS model inverte...
