Good point, Nullarbour and all that. As it is, the max distance between service stations out there is around 137km ? from memory. We all know of a lithium batteried Mustang locally that could make the trip station to station right now and potentially recharge in less than an hour. So we are not real...

Regenerative braking

Hi Turtle, Home grown conversion. Guess you're talking red suzi here. Like a working man's version of an AC Propulsions AC-150 http://www.acpropulsion.com/ nice bit of kit, but at $35k + some serious batteries you start to look $100k in the face ! http://forums.aeva.asn.au/smileys/smiley11.gif My EV...

NCOP14 regulations, venting of battery

I'm working through the NCOP14 document (see waeva links) and I am questioning the need for vented battery boxes when using sealed (SLA) batteries. True these can gas under extreme conditions of overcharge but will not release any gas (hydrogen of most concern) when a battery management system is in...

Yep. You see, the oil companies don't mind selling you half as much fuel. Then they can double the price and will still make the same money out of you while you think how great it is that you are making a "saving". Personally I think hybrids stink ! They are after all a very complex half measure unt...

Image ...but if plugging into a 10Amp 240V single phase outlet is an "inconvenience" then just wait till you have a 70kWh battery pack and you have to find a 32Amp 3 phase outlet to plug into !!!!!

Regenerative braking

I have regenerative braking on my AC motor conversion. The controller will regenerate down to stop with as much torque as it will accelerate. So much so that I rarely use the brake pedal at all. Surely you would only not have regenerative braking if you ran a series DC motor and regeneration was not...

fast charging

There is an obsession with fast charging where people want to be able to 'fill' their car in 10 minutes. This is presumably to make it comparable with their IC motor vehicle in use. (see post on changing habits and expectations) The problem is not in making the battery technology able to charge in 1...
