Crashed my i3 - 9.40pm Sunday 22 Jan

Well I had to look that one up. http://www.commutercars.com/au/ Specs look interesting. But DC - really. So what $$$ are they talking for a Tango $45-50k? You'd be better off with one of those kit cars from that mob in Willetton. http://www.southam.com.au/home.html I must be wrong... "Quantity     ...

Are commercial VFDs tweakable?

Hi Luke. Woody's final comment is the key. The current a VFD can provide is the main factor. As for running lower DC Bus voltage on a Lenze. That would be a pretty major re-engineering project. The Lenze drives run entirely from their DC Bus which means they have lots of switch-mode power supplies b...

80V lithium -ion Victa, etc., battery packs

It's quite amazing that trawling though various web pages and even finding folk who have re-purposed these 80V batteries, no-one seems to have reverse engineered the "third pin". Most packs and tools appear to have one (a 3rd pin). My guess is to connect it to battery negative - but that could well ...

GBS cell smell question

Jason, have the cells been exposed to temperatures in the 30s or near 40 degrees C?
If they are in an enclosed space - which you later opened up even a small amount of solvent venting would smell pretty strong.
I'd test all the open circuit voltages and if they look fine - they probably are.

The iCar is even smaller than the colt. The iMiev wasn't built as an EV originally - it was ICE powered. The iMiev is an iCar with the powerplant replaced.

DIY Conversions nearly dead ?

Hey Digger. I spent about 4 years building my DIY EV. Most of that time was restoration work to be honest. About 1 year before it got on the road I was regretting it because the iMiev and LEAF cars were becoming available as ex-dealer demos. Had I not have been committed (effort wise and financially...

b) How come it worked fine for the last 7 years when wired the same way? Again thanks Paul It works fine now. It's just that someone proved that the traction pack isn't isolated from the 12V system. TBS clearly say that the device is not isolated so the only way to ensure that it is would be a 12V ...

I took the liberty yesterday to contact TBS Pro about the HV to 12V "leakage" issue. They responded today (quite quickly). The mail trail is a bit confusing bit the answer is in the immediately following text. In short - the TBS Pro does not isolate supply voltage from the HV pack. -----------------...

I can't seem to find an installation manual for the TBS Pro. There's a lite and an E-Xpert but they don't tell me much. The lite shows that the Aux battery (12V) and the traction pack shunt are connected but I'm sure that is not how yours is wired. Have you got any diagrams etc. that show how it's w...

My guess is that the Ioniq will be around AU$60K. Bjorn makes a comment somewhere in his video that it's a third of the price of a low-end Tesla in Europe.

Hmmm. 480kW (just assuming a bit more) at 48V - that's 10,000 Amps.
Yeah - that's OK. Silicon losses - I guess MOSFETS.
Dunno - I don't believe it.
Either false or some trick of the marketing dept. Maybe all the flow cells are in series and the rest is internal miscommunication.
