Ahhh Japan. Always interesting and never disappointing

I'm sure something can be arranged.

I had a chat with the Aircon guy and he seemed to think the current condensor might not be up to the task of both cooling the cabin and keeping the battery cool. The compressor is probably powerful enough, and the blower evaporator is fairly small (can be set to the lowest blower setting) but the ba...

That's a bummer. What voltage is the DC/DC converter designed for?

I was just checking in on this thread today wondering how it was going!
How does it feel to know that your cabinet costs more than the cells it contains?

The SP Pro is one of the most highly regarded inverters in the field. Should give plenty of reliable service.

I'm not so sure that the DC/DC converter or the TC charger is to blame here. I have been successfully charging and driving the Prelude without a properly functioning master contactor precharge circuit. At least a dozen on-off-charge-off cycles. The minitactor and Gigavac GX14 contactor inside the ba...

Hi All,
WA branch will be having it's monthly meeting at Curtin Uni on Tuesday the 12th of November. See you at building 301 (Physical Sciences) where a couple of recently completed conversions will be on display!
Cheers,
Chris

Hmmm, time to see Ian again.

I think there must be some capacitor that needs to be precharged. The master contactor should only switch under load in a fault condition. Have you tried to put a precharge resistor and checked that it is not trying to switched into a discharged capacitor? Yes, that's why I installed one, and it's ...

Well the aircon compressor is likely to be installed at some point this week. I'm wondering what the best approach here is - I think I will need to install a better quality master contactor precharge delay timer for a start, but the risk of a master contactor sticking is pretty real.

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...

New coilovers fitted - the car drives like a dream :D They are set to give about 140 mm of clearance all round, but still offer good damping over some of the usual bumps. Getting harder and harder to hand this car over! New ride height.jpg However I noticed when turning the car on it would still giv...

Well now that I've finished the Prelude I can finally move on with fitting the 60 Ah cells to Pauline's iMiEV. Will make it a bit more useful I think.

I think the motor is speed limited. Rod Dilkes will be coming around on Monday night to mess with the settings a bit. It would be nice to have more torque than its current settings, as taking off in 3rd is a bit sluggish and 4th is way too slow for most circumstances. We also need to bump the regen ...

Yeah I am very impressed. It seems to hold about 95 km/h in 4th gear, top speed. This is no doubt a controller setting which I hope to change on Monday. Otherwise 5th gear is fine, and has a top speed of about 110 km/h I guess. No need to exceed 100 most of the time. It seems in stop-start traffic t...

I took Roe Highway home today to check the car's energy consumption on the freeway. At 100 km/h it averages 13.5 kW :o If there is a slight incline, you might see 20 kW, but it soon drops to under 10 kW as you crest the hill. So on net flat ground, the electric Prelude has a highway speed range of a...

Can I ask did you do most of this yourself or did you get the odd bit of help from ppl? I did most of it myself. The adaptor plate was drawn up myself, but I got a mate with a big lathe to finish the job. A few friends helped with the pulling out of the oily bits (between cans of beer) but most of ...

I've been using reecho 's OpenEVSE on the Prelude while I test it. Unfortunately it's the only EVSE which seems to work reliably with the Prelude conversion. So I will be inclined to buy it (or a similar single phase version) for leaving with Francess. The 3-phase cables are way too heavy for the job.

Suits me. Wonder when we'll see them?

Thanks for the advice on the contactors - makes sense that the bigger ones don't stick as much - more heft of copper to throw around perhaps? Another good test-drive to work and back today. I went via Cockburn to visit Jon Edwards and his DC powered fast charger. Not that the Prelude could use it, b...

No wonder children and animals die in hot cars!

The Mosman Park Men's Shed are hosting a craft fair on the 10th of November and the AEVA will be displaying a selection of EVs. Please get in touch with Ant or Myself (secretary@aeva.asn.au) if you want to display a vehicle or bike. We need to be there at 8:30 am for a 9 am start, as once the vehicl...

I think it resides in the correct forum

I'll have to get a number on this tomorrow, but about 21 kW I think. It takes about 8 kW to maintain 60 km/h, and 14 kW to do 80 km/h.

I should add - the wobble board effect has been reduced somewhat, but it's definitely still there. I need to mount a gopro under the car and go for a drive to see what's happening. Hopefully the new coilovers will fix a lot of that.
