Re: Hot rod EV - looking for advice.

So cool and so green with NV for your EV.
Recipient looks very cool.
Can you just use it at the same track width (Wide track is always cool), I'd even say its easier to stretch a body than it is to narrow a drive train. (Worked many years agon with stretched and widened Range Rovers to UAE)

Super keen to hear how you go and will be interested in what you can come up with in terms of replacement/upgrade of the pack.

Re: minicab miev

For us we don't need it for freeway as yet, ours is just the city car, its gets used so much and the other car gets left in the garage a lot and only brought out of if I don't ride to work (raining) or we need to go to sydney. It can do freeway speeds but not the sort of car you'd use for those trip...

Just got myself a 2012 Minicab and on the NSW Central Coast.
Keen to hear any progress with delimiting motors or battery upgrades and keen to be involved.

Just got myself a Minicab and on the NSW Central Coast - Super interested in where this goes and keen to assist where I can (Not very electrical but am a Mech Eng willing to learn). A few of these coming into the country so would be a worthy market for battery upgrades as they already have no warran...

Sydney meetup 19-1-16

Hi there, I'm keen to come, I haven't started my EV project yet but getting closer and keen to meet and chat with people before I buy any components.
Have purchased a clean (but gutless) BMW E46 which will get the transplant if I solve a few other challenges first.

Weber and Coulomb's MX-5

.... hopefully getting the belt pulley from the ICE mounted there to drive the aircon and power steering. I am intrigued at this, being new to EV but not knew to modifying and driving/playing with cars this doesn't make a lot of sense to me. (doesn't mean I am not missing something) Power steering ...

ABB motor and VFD selection

Your right, for a street car, 160k/h is plenty. Based on typical wheel diameter this would give a desired rear diff ratio of 4.48 for 6000rpm@160 which puts it close to an available 4.44. What ratio are you aiming for in the Ev30 Richo? What sort of % nom. torque could be expected at 400% nom speed ...

Yeh my thoughts of the AWD is on the back burner and think I should keep it simpler for my first EV, thinking more along Richo's path but an E36, 250kW sounds close to what I want http://forums.aeva.asn.au/smileys/smiley15.gif but yes the controller is where all the grunt has to come from.

ABB motor and VFD selection

Check out red suzi in member's machines for more info. I don't use all the 6000RPM now (controller too small) but this rev range issue is my point with 2 vs 4 pole. Your even less likely to be able to use 12,000 RPM ! Aim to select the torque required of the motor. The kW is very flexible. Wow, so ...

Two motor direct to diff vs gearbox AWD

I too think AWD but wondering if its really necessary in my aim.
For your offroading aim I think it could be tops.
Subaru R160 (yours and mine) diff ratios range from 3.54:1 to 4.44:1 I am sure a 4.44:1 would give plenty top speed and a good low down response.

Yeh, works well so far but a mate and I are trying to make it better. Subaru had auto DCCD from 05 STI I think (maybe even earlier), 06 STI DCCD works quite well, it uses YAW rate, steering angle, ABS wheel speeds as well as Lateral G and TPS. The problem with teh OE one is its not programable, so a...

Two motor direct to diff vs gearbox AWD

I intend to take the car off road, so 4WD is a must. My main concern is having one wheel in the air - would that motor take all the power away from the other one? (like an open diff), or would it behave more like a limited slip diff? With two motor controllers you could easily divert power to the m...
