Sprintkhana/WA 2014 sprints - i-MiEV / Volt Barbs

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.

Electric Karts

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.

dogphlap's Jumbuck

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...

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!!

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...

ECU coming on board is great also. As Clay said the previous committee was dissolving and without renewed efforts it i...

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...

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...

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...

barnard's Toyota MR2 - now Mr240

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...

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...
