Re: Making home EV ready

Terry - I think the Kona is either 96 or 98 cells in series - when fully charged it hits 400-407 V DC.

Re: 9 Nissan Leafs for auction at Pickles: 8 NSW, 1 ACT

I have recently placed a deposit on an ex-fleet Leaf which was on sale here in Perth for $15,000. With 31,000 km on the clock, it was clear the battery was degraded. However after paying Nissan to do the diagnostic test they realised it would be a major failure in the eyes of the ACCC, so they are g...

Re: Prelude conversion project - some questions

Another productive weekend, and probably only another day's work to have it rolling again. I connected all the BMS wiring, added some silica gel packages and seal the lids. Once the lids were on I could put the new top brace across the three modules. I bought a MAPP torch and some aluminium brazing ...

EV Fact Sheets

Hi all, Unfortunately our incumbent website limits what goes where, and how prominent an article is, meaning really important stuff sometimes gets lost in the ether. One particular resource are the EV Fact sheets which Bryce and Chris Nash have been compiling - these are really well done and rich in...

Re: Rural Fast Chargers + Servicing infrastructure in Rural areas

Hi Doug, Happy to catch up with you while we're in Sydney. I think we're covering a lot of this ground nationally already, so it's mainly a case of joining those already working on it and helping the cause. Understandably difficult for the non-metro areas granted. Many of the bodes who we need to wo...

Re: Prelude conversion project - some questions

I decided to fiberglass the lid today, leaving space for the main HV leads and coolant lines to exit the back corners of the battery pack. The work in the middle is where the coolant return line will go. Obviously it didn't quite clear the 4WS rod, so it will need a patch-up. 20191006_182241.jpg The...

Re: Prelude conversion project - some questions

Productive day working on the Prelude today. I picked up the new EBP25 water pump from Chris Mills Performance, which was no doubt an expensive way to buy it, but shop local and all that. It was a bit tough to install because of its location, but since I was replacing the battery charger anyway it w...

Re: Soyachips’ Electric FZR250

I love the battery pack enclosure edges - very nice. I presume they're pretty strong?
Nice work on the brake caliper too - the rear brake and wheel alignment can take ages to get right.

Re: 4Springs' Home Battery Storage System

That is an epic setup. Awesome.
Is there room for more cells in that space or will you settle for the 22 kWh?

SP Pro is the ducks nuts of off grid inverters so it's also a safe bet as far as the network is concerned.

Bingo.

The car is already expensive, so paying an extra $2k on top of it seems stupid, especially when the unit probably won't function like it should in 12 years time.

Re: Power Steering failure when in use battery drops 13.5 to 8v

The Astra power steering pump will draw 25 amps just to maintain pressure, and as much as 60 amps when ramping up to full lock. It could be that your DC/DC is not up to the task?

If nothing else, a permanently installed EVSE makes plugging in even easier - get out, plug in, walk off. No faffing around with sockets and leads.

Re: Prelude conversion project - some questions

The new battery floor is almost ready. I have swapped module 5 for the spare module I built first. It's balanced and all the cells seem to be behaving, only thing is the thermal epoxy coverage wasn't as good. At this stage a battery that works is good going, cooling is a bonus. The big lump of 100 m...

Re: Leaf in the tropical north

I hope to have a Leaf to play with soon. Only after a while though, Katherine would need to give her blessing :)
If nothing else, pulling air conditioned cabin air through the battery would make a world of difference.

Re: Leaf in the tropical north

Something I've always wondered, if heat rises and cold falls, wouldn't blowing cold air above the battery pack and exhausting it below the battery pack a better method for cooling? I see all these cooling plates the cells sit on, but wouldn't that be the coolest part of the cell? Tesla run pipes up...

Re: Leaf in the tropical north

I was doing research on the sandalwood plantations up there during my PhD and post-doc. The latest I was ever there was October, and that was pretty rough! I agree it will be difficult to keep the battery cool. Matt's probably right - a conversion with LiFePO4 batteries will handle the heat much bet...

Re: Tc chargers dont like me. I have killed it.

I don't think these chargers are easily serviced, but it could be that an internal overcurrent device has tripped. Or a fuse on the AC side has blown internally? No LEDs all together, whether plugged into a batter on the DC side or a socket on the AC side would suggest it's not getting power from th...
