Video on the dyno.

This curve might be a better representation , but the speed maxed out abt about 60km/hr

Scatter plot of RPM vs. Torque, Power



(Power is 10x.) The above data was captured from the Danfoss VFD.
This would indicate that the Dyno run yesterday did not reach peak power / torque.50km/hr = 2100 RPM. The motor torque from the dyno plot at 50km/hr would be 2100*.323/5.125=132Nm. This (very roughly) corresponds to the scatter plot at that RPM.
The dyno plot can be for all intents ignored unfortunately. I will go and see them and see if they can do plots at multiple single speeds.

Tesla Coils and Doctor Who! I saw these guys minus the conductior at the Maker Faire in Austin, TX last October. The performing coils have to be seen and heard to be beleived!

Dyno run - Curves

I took the Electro-Lux to a local Dyno Day today at Envy Imports. The revheds enjoyed seeing something different. I think I get the record for the lowest power and first ever EV on the Dyno.

My diff ratio is 5.125:1 and my wheel radius is about .323m.

400km so far and no major troubles.

Today the speedo rolled over 400 electric kilometers.

There have been no significant problems, just some minor niggles.

I am confident that as long as the batteries live up to expectation I will get many 1000's of EV kilometers.

Minor changes include:
  • Replacing one battery due to a loose terminal.
  • Replacing 2 x Zener balance circuits due to mismatch.
  • Adding a series resistor to the 7 solenoids because they were getting too hot.
  • Adding an electric fan to the motor to cool it down after long up hill stretches.

Selling my hilux engine and power steering.

I am finally cleaning up the car port (Yes car port, I did the hilux conversion in a carport, I dont have a shed).

The old 22R engine and and power steering are listed on eBay http://shop.ebay.com.au/merchant/a4x4kiwi

I have been sorting out some old photos and videos from my camera. This is an old video from December 2007.
