I should have added that Jeff would never use them. But you can't help noticing things like that when you drive an EV. The ethical side seems not too much of a problem for me. Driving an EV and borrowing a bit of electricity in emergencies is still better than doing nothing! But running an extensio...

I'm guessing 30 to 50 km depending on lots of things. Great, at least I'm probably not out by orders of magnitude! I'll try some more maths: Driving 25km at 80km/h takes 18.75 minutes. 8640Wh / 1h = 8640W. To use that energy in 18.75 minutes the average power would have to be: 8640 * 60 / 18.75 = 2...

About the low range but high power which I want, and the ICE generator: I figure that I will not be able to afford and fit enough batteries for good range. So I want batteries for sufficient range only. That keeps price, weight and space requirements lower. If the many battery technology improvement...

What donor car could be used to be turned into an EV that still allows 2 adults and two children and shopping to be carted around? That's what many people I know need. A reliable 25km range at 80km/h with stop-and-go and many hills, more uphill than downhill would be enough. Acceleration needs to be...

Project Better Place No3 is Australia!

Here is a graph showing the charging energy consumption during and after the 187km ride: http://i281.photobucket.com/albums/kk217/Mr_Mik/Vectux/Battery/ABCool/OverlandRideRechargesTotal.jpg The data logger also calculates total power consumption and cost.

Electric Vehicle Subsidy

Project Better Place No3 is Australia!

There were just three EVs present. The prize for the longest commute went to Mr Mik, who drove his Vectra from the Gold Coast (~100km) using several charging stops to get there (and the same on the way back, of course). 187.3km in total...I'm not doing that again in a hurry! Many thanks to the Outp...

Oscilloscopes - at what level do you need one?

It depends if you want to go to component level with controllers. Some controllers (e.g. Curtis) are potted, making it difficult to even get the thing apart at all. I guess the cost of the bigger controllers justifies component level repair, which could require a 'scope. .... .... Are you (semi) se...

Oscilloscopes - at what level do you need one?

I'm just wondering if it would make sense to snatch up an oscilloscope if - or when - the opportunity arises. Would you need one if you were running an "EV Clinic" which tries to diagnose, service and repair any type of EV that come through the door? Or to run an Electric bike repair shop? To do you...

Hi Justin, as discussed earlier, I'm planning to stop at your place for the third charging stop on the way there, and for my first stop on the way back home. I hope to make it to your place by 0930am and will need about 7A @ 240V until 1100am to make it to the event in Upper Mt. Gravatt. I'll bring ...

And Gold Coast!

I've got three recharging stops lined up to make it there!

A scenic route through the Hinterland.

reverse cycle air conditioning

I doubt water would work for the purpose. It is not compressible. Another issue is that reverse cycle air conditioners seem to need a safety break when switching from one direction to the other. At least the ones I have access to: If you change your mind and switch the running AC from one mode to th...

Home grown BMS ideas !

Hi, I read through the thread and most of it is (so far) way too complicated for me. But I have built and am using a Manual BMS (M-BMS) in the 102s NiMH battery of my Vectrix, it's homegrown alright, and might help to cross-pollinate some ideas for the more automated BM Systems you are discussing he...

My main concern about swapping batteries is that they need to be looked after. Putting effort into giving your batteries a long, strong life is somewhat incompatible with throwing them back into the "pool" every now and then!

Hi, I'd like to attend at Mt Gravatt. To get there in style, I need to have at least one recharge between the Gold Coast and Mt Gravatt. Anyone interested in lending me 2hrs and 4.5kWh, somewhere around Wet-and-Wild, Movieworld etc?? And the same for the way back, please... Is there another thread s...
