Why get an EV?

If it so happens that it is proven that you can take any reasonable vehicle and convert it to Electric for under $20,000 it surely will send the message that commercially produced EVs should not cost the earth. Very true. But can you? The most successful Australian commercial converter, BEV, charge...

Why get an EV?

I think another problem is that the car manufacturers are scared of bringing out a car that is not extremely good and completely without foibles. None wants to be left behind but none wants to be remembered for being first with a lemon. Consequently they are like the penguins that jostle at the edge...

For what it's worth my views on climate change are more influenced by my colleagues at CSIRO and other academic institutions and respectable scientific literature than by Kevin Rudd. The standard arguments repeatedly put by noisy sceptics have been comprehensively debunked or acknowledged and incorp...

Why get an EV?

To the question why have an EV? For me the main reason was that I can have the luxury of private car transport yet run it on renewable energy by buying 100% GreenPower. I could justify this as a cost-effective way to reduce my environmental impact because the cost is less than running a petrol car. ...

What limits an E-bike power?

Thanks, that makes sense that I would need a controller then. I guess the main question remains though: is the only difference between different power rating actually in the controller not the hub motor? Anyone else know?
Thanks,
Peter.

What limits an E-bike power?

Hi, After looking at the various hub motors on ebay, shops and elsewhere I am coming to suspect that the motors from any particular vendor are the same internally and it is only the controller sold with it and the recommended battery voltage that provides different current or voltage limits. IE if y...

DC/DC converter box for solar panel on EV?

Hi, Feel free to join in some idle speculation if you feel like it... Thanks........ I know it would probably be better value to put an extra few cells in the car and put an extra few PV panels on my roof since my roof stays in the sun whenever it is available.

any transformer experts here ?

It does say autotransformer on the label. Is there continuity between all terminals? That would mean one long winding. Maybe it is for transforming mains voltage at modest current (on the two smaller terminals) down to very low voltage at very high current (on the two large terminals)?

Sounds good Peter. What sort of distance have you travelled and roughly how many charge cycles? Do you get to part in the shade once we hit summer? An early calculation in autumn when I had only done 700km was 250Wh/km. Just after that it got cold. At 1400km the calculation came out at 265Wh/km. No...

No idea if this is the safe limit. I wish I knew. On one hand I would like to be kind to my cells. On the other hand, if it doesn't do any harm, I might put my foot down a little harder in winter. The EV Power BMS alarm is intended to warn if any cell has hit 2.5V through discharge and warn you to s...

5 months on the road now. Still goin well. No problems. Through the Canberra winter in an open sided carport with frosty nights the max. current before the BMS alarm (2.5V on at least one cell) would sound was ~200Amps (cells in the 0-10oC range). Now it is warming up the car is decidedly zippier wi...

The AGM is Saturday night. The field day/open day on Sunday has evolved into rather more than just members and vehicles, although that is a crucial part of it, hence 'EV Festival'. There will be plenty of other things to do around Canberra. The EV Fest is on in the parliamentary triangle with Questa...

how much power

My motor (ADC8") is capable of more peak power (~60KW from memory) than I can get from my battery (~40KW max (product of volts and current)), and that is when it's warm. Cold (zero to 10 degrees) I am getting around 25KW max. Getting a powerful enough motor may not be the limiting factor.

Mazda says it is not going EV, Mitsubishi says it will never build a hybrid, just go straight to BEV. They both seem a bit odd to me. We have two cars.

DC-DC converters, how much power do we really need

Does the curtis make the contactor open every time you lift off the throttle? Weird... That is how their manual recommends configuring things and how I did it. They also recommend a resistor (several 100ohms from memory) to bypass the contactor to 'pre-charge' the input caps of the controller but n...

Hmm. I have my DC/DC converter hooked up after the main traction circuit breaker but before the contactor. Consequently the DC converter has power available all the time to supply lights or anything else when the car is not running and the battery would not charge or discharge unless the DC converte...
