Re: Odometer tax?

There was another segment last night on the Drum on ABC on the same subject. (Adam Spencer)
It seemed more objective rather than beating the eV community into the ground.
But they went off topic a bit about autonomous vehicles.

Re: Odometer tax?

All irrelevant tho.
On the TV show last week "10 things.. about the future" - we are getting flying cars!
The irony was that they thought we needed some complex swarm algorithm to stop people crashing into each other.

Re: Odometer tax?

I did hear the ABC mention it on the radio around 6am. My guess is they want a scapegoat to blame for the bad state of affairs with our revenue in general. Not including the AEVA ppl I have only seen ONE(1) person with an ev in the past year. So I don't know where this suddenly flurry of ev's went t...

The next thing down from the fork/walkie motors are the electric pallet jacks these range from 1.5-2.5 kW.

Any idea what RPM those would do Richo?
Yeah crown don't publish their motor specs - not surprising.
Based on other similar function motors they are around 2,000RPM.
And that comes down to load and voltage.

Bills has crashed so I don't know - I'll check later. In any case not so close to NSW for Dellas to buy - there probably is a machinery scrap yard in NSW that would be better. eBay item 253352394091 is about 140km away and after $50 for a motor for $150 for the lot.

Re: Labelling of Battery Compartment ???

You can see that this one is held on with a screw at each end. When the label is heated by the sun it expands and bows up - slightly annoying at car shows. I'd recommend not using that method of fixing such labels. Ask them to put 3M MP467 or similar on it next time. They should have this already i...

What I’m wanting to know is what sort of stuff do I need to buy for her to achieve this? The motor needs to be able to spin fast enough to mow and slowly move the mower while mowing. Sounds like a realistic objective. The mower has a hydraulic drive gearbox running off a pully, the cutting deck has...

I saw the news report on this - very nice!
The aim was to do the Rotnest Island runs.
The other aim was to help reduce running costs for pilot training.

Re: BMS card warning

It is not a matter of 1 PCB. Its 4 with the exact same alignment error. As 'adverse Effects' rightly points out, if there are 14 channels then each one must be the same. And I keep telling you electrically they are the same - follow the tracks. It's not hard even a 5yo can solve those pencil in maz...

Re: BMS card warning

As I mentioned in some other thread the cheapest 18650 are like $1.30 and still have some capacity - 10% of what they claim but enough for testing purposes. The BMS is supposed to prevent over charge, over discharge and keep them "balanced". So it would be hard to explain user error for a fault. Fro...

Re: BMS card warning

1 of these things is not like the other You are correct it doesn't LOOK the same. Dont get hung up on that one resistor it's NOT the problem. Electrically it is the same as the rest. It's only in a different position due to the C- track. I think a lot of EE's and battery builder out there will be t...

Re: BMS card warning

He could - but the answer wont change. Electrically it is the same as the section above it. Even I can tell that from the blurry photo's above. The reason this particular resistor is different is because the C- track comes in past it. They could have turned it 180 and tracked it the same so it looks...

Re: BMS card warning

I doubt the part you have highlighted is an assembly problem. You'll notice the silkscreen is also different to allow for the odd placement. The tracking appears to go to the same place as the others. The only way it could be wrong is if the engineer didn't make the schematic correctly. Unlikely. It...

Re: Fonzarelli X1 - 13 kW motor!

Matt might have better info but the Vectrix had a similar top speed but had a peak of 20kW (50% more power).
I'd be surprised if the battery weight had that much difference.

Re: Fonzarelli X1 - 13 kW motor!

Sounds pretty good. Most of the generic brand hub motors are sub 5kW. There are no regs on power for an electric scooter it's only an imposed speed limit. So unless it's limited to 60kph (depending on state) it can't be classed as a scooter. So it would be registered as a motorbike and you would nee...

Nah I doubt it's a torque sensor.
Just a simple hall(position) sensor.
Even if it is a torque sensor the base electronics doesn't really change much.

Re: Drive an electric power steering motor from an European Opel Corsa C

The motor may likely be driven in following two ways: Reverse engineer the torque sensor. Input "fake" torque readings to the original ECU and let it drive the motor. This method may be easier but may not give precise control of the motor since the ECU will still behave like a black box and will tr...
