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...

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...

That should only matter for the ones sitting right-way-up in the middle of the battery pack. All others are normally on their sides, but these can be made to work standing upright.

Today I started to assemble the new battery floor from 6 mm plate aluminium and square hollow section. A total of 8 countersunk M8 high tensile bolts hold the central beam in place, while the front gets a single length of 19 mm SHS which serves as a bit of stiffening, but mainly a solid stop for the...

What size fuse are you using? Semiconductor fuses do weaken over time if they're undersized (current goes above the continuous rating on the regular but doesn't exceed the I2t rating) 200 A Bussman.

I don't know either - all I know is that the ZEVA wasn't giving an isolation error before it blew, and now it does. I never saw the current exceed 180 amps, but it's possible that it had been 'singed' at some point driving up the hill and the big bump might have weakened it? But I still had power as...

Now that the charger can charge the car, I decided to bypass the master precharge delay and charge the car fully. The Enable feature stopped the charge as soon as the first cell exceeded 4.2 V, which is good. Since the car was driving so I figured, before I go and immobilise the thing for a few week...

No, this is still with the original Enable-only charger.

However my goal this weekend is to install the new battery floor with provision f...
