Re: Which Motor?

The car in question only had 34kW.
200V / 75kW would be plenty - no rewind and no gearbox.

How much does the motor weigh?

I have decided that a Leaf motor and differential is probably the best option for the CRX.
Wow I haven't seen one of these yet to buy.
That's how I ended up with the Hyundai motor.

Any clues how much the leaf motor+transmission costs?

The motors I have will do 260Nm at 5500 rpm from a 400v battery.
Well that would be enough for direct drive in this case - hills included.
400V maybe too high though for direct drive on something that only had 70kW.
200-300V would be ok.

For example on the right it says torque and power so not sure if 30 means 30kw or 30Nm.
Ah its both.
Only the colour of the line makes the distinction between kW and Nm.

Re: i3 and i8 drive ratio

The i3 says 9.665:1.
There is a nice graph of the power/torque graph.
Peak at 4775 RPM and max RPM 11,500.

I'd always trust info on a data sheet over a promo video.
The old Azure dynamics AT1200 was about 10:1 so nothing really outlandish from BMW.

If anyone has any more cheery news I would like to hear it!
Well if you got a 200kW AC motor and 3-4kWh of high performance batteries it would cost about the same.
It may not get to where you want to go bit it would be a crazy drive :twisted:

Re: Toyota Hiace poptop conversion

So that's $19k and you still need chargers, bms, fuses, wiring, lugs, battery boxes, adapter plates, motor mounts.
and lots of labour.

perhaps all up $25k + labour

Re: Toyota Hiace poptop conversion

If you just go all out for 150km range you'd need more like 27kWh.
So about $18,000 just for the batteries.
AND wait for it... 431kg.

So there is no way your pop top can handle another 431kg.

So LiFePO4 are out of the question.

12 x 12V60Ah -> 144V60Ah -> 8.6kWh $5,760 ~40km range I live in the city and most camping area's are way further than 40km. Given the car is loaded up already I'd be surprised if you could even put enough batteries in it to go anywhere useful before you get to the GVM. Any ideas how far you were hop...

Pedals...

It's the same with the pedelec scooters.
It looks like a scooter but they ride them on the foot path, no rego etc...
Only because it has pedals and a claimed power of 200W.

Put pedals on an esky and it becomes a bike and is perfectly legit.
