Well done you, Joseph.
You are one of the best advocates for EVs!

I would love to bring the Proton up for a spin but would have to put a lightweight battery pack in it to get anywhere near competitive handling. Better start saving my pennies.

Maybe we can practically start with an E-kart Challenge at next years Perth Electrikhana?

For safety it could be done as an autokhana type event around a cone track, one kart at a time.

Having a standard chassis and very low COG E-karts would actually be very safe.

Good to see some new blood getting enthused.
I didn't know there are already E-Kart venues.

When is the next one Joseph?

Quoting Chris's race report here... If any other teams have race reports and/or pics please post or send to me and I will post. Thought I might do a little race report of round 2 of the eFXC at Winton Raceway last weekend, thanks to team O'Hanlon Electric Motorsport ;) Pottz and I landed in Melbourn...

Good choice of car ;) We have converted three Jumbucks now. All still going, touch wood... The best thing about a front wheel drive ute is there is plenty of space under the tray and they are built to carry a load. Jumbucks are also mechanically and electrically fairly simple. You need to keep the b...

Congratulations Chris, Mike, Danny and the gang. Chris you really believed in yourself and risked everything, I think thats what got you to the start line and what got you to the finish with flying colours. Its inspirational stuff. Congratulations also to the other competitors for making the race po...

You have to take the record for "men in sheds" Chris.
At 9sqm your shed is something to behold!

Its great that you are in a position to take the lead on this.

If an electric can go head to head with fossil fuel burners and have a winning edge, that's really the beginning of the revolution!!

Congratulations to you.

Its been a long time coming... I think discussion started on this in 2008. Finally we managed to bolt a motor on the kart gathering dust in the shed all these years. It has a Motenergy ME1114 PMAC motor and a Sevcon Size 2 80V controller. 24 x Headway 15Ah LiFePO4 cells. We were doing lap times comp...

I haven't been following this thread and it was just drawn to my attention. Clay and James (Coulomb Racing) are to be congratulated for their efforts to keep the EV Challenge going. ECU coming on board is great also. As Clay said the previous committee was dissolving and without renewed efforts it i...

Well I agree about keeping up with the traffic, esp on the highway. I have no intention of being a road block. A microturbine generator the size of a loaf of bread can produce more than enough power for a car. http://www.capstoneturbine.com/_docs/cmt380_lowres.pdf Its a pipedream for me but for some...

Thanks. The next big challenge is to find a way to make it drive the 270km trip from Margs to Perth. Maybe better batteries, maybe a genset. Suggestions welcome. As always its still a rolling testbed. Tuning the Size 8 PMAC controller to the motor has been a real challenge but it is going pretty wel...

After 4 years my Proton Jumbuck conversion has finally passed registration. Wooo Hoo! Finally street legal. Its a big day really. In the meantime I have been through two controllers but the motor, which I expected to fail, is still holding up. http://www.evalbum.com/3412 http://forums.aeva.asn.au/up...

ITC Global EV Challenge, Perth WA October 27th. Around 24 teams will bring out their Electric cars for the ITC Global 2012 EV Challenge in Perth, Western Australia next Saturday, 27th October.    As one of a handful of electric car races around the world, this is a rare opportunity to see grass root...

The one in my Proton Ute is an early model Unite BLDC motor. Its good for me but a bit coggy off the mark. We installed a GLE PM20 in my offsider Jamies Proton ute and it is pretty slick. It is smooth as driving a Nissan Leaf. It has respectable performance all the way up to 7000 rpm so driving arou...

2. more searching led me to a supplier in vic or NSW of "meanwell" power supplies. i ended up purchasing a SP-320-12 model for $70 plus freight! smaller and larger models with varying input and output voltages. i cant understand why the ev suppliers havent caught onto this yet. Well researched Bret...

We have had quite a bit of success with the MI15 and PM20 Greatland Electric motors from China. There you go folks, the cat is out of the bag! I have had people plying me with questions about these AC motors on our website for months. Everyone who inquires wants to know who makes them so they can bu...

Without knowing who it is, my sympathies go out to them. In this case it could have been alot worse. It should be a warning call to all of us in the EV enthusiast community that these batteries are not benign. Under certain conditions even LiFePO4 batteries can burst and catch fire. They are safe in...

This is very interesting research! Correct me if I am wrong but this does seem to indicate that LFP cells tend to go out of balance more as they age. In Barneys situation where the battery pack is relatively small compared to the mass of the car it would appear the ageing process has been accelerate...

Does anyone know anything about this incident? http://www.cfaconnect.net.au/news/electric-car-starts-garage-fire.html Including text here: Torquay responded to a Garage fire at 5:35am Sunday morning. The first truck found the garage fully involved and threatening the rest of the house. Further infor...

As far as I recall the EV Power cell modules have always been set to 3.6V bypass. The upper and lower cutoff thresholds have altered over time. In my own EV I have used different BMS cell modules from different model batches as well as different brands and capacities of cells, all in the same pack. ...

The cell modules are designed to switch on shunt bypass at 3.6V. At about this point the red LED will switch on to indicate bypass. It will not switch off till the voltage drops back below 3.6V. Overvoltage point is set to about 4.0V at which point the green OK LED will switch off and the current lo...
