Hello, My name is Robert and I am new to this site and at the current moment I am trying to Learn as much as I can and as quickly as I can so that I can ask you all the correct questions without annoying you or being bothersome.

So far being on this board, it has been spectacular. The amount of Information is overwhelming and immensely enjoyable ( I just wish I had more time in the day to keep reading ).

I plan on converting a Scion tC (Toyota Avensis chassis to those in Europe) into an electric.

However I need help with the motor. I would like it to be a Daily Driver and I drive long distances, its not uncommon for me to drive 160 miles in a day. But I would also like to have performance with it. Ideally acceleration to cover a quarter mile in under 12.5 seconds preferably in the 11's.

Can it be done?

Also I am a little confused with the pro/cons of dc vs ac motors. Which will be better for my application?

I have been looking at the Raser P-200 motor... is it any good or are there better options out there?

My budget is very open, I do not mind spending if I get quality parts, the job lasts, and is done right. I am also discussing sponsorships with some companies to fund this project, hence why I said I am very open to this.

Also is there such a thing as too much batteries? I happen to have a lot of room for batteries in this car and would like to use it up, preferably with lithium ion.

Thank you very much for your time and assistance, I greatly appreciate it.

Displacement: 2362 cc

Power: 160 hp (119 kW) @ 6000 rpm

Torque: 163 ft·lbf (120 N·m)@ 4,000 rpm

Transmission: Standard 5-speed manual transmission

Hi pol,

I'm afraid you'll have to stick with motors which are actually available. Raser is not. AC is nice if you can afford it.

Thank you for the quick response, what motors are available that would/could offer the goals that I am looking to accomplish? Or at least which ones would you recommend for me to look into/start researching?

Hi pol,

I stay away from recommendations. Too many unknowns. Suggest you nose around the EValbum and DIYgarage. See what others have. And see what the vendors offer. You may find this interesting. http://en.wikipedia.org/wiki/AC_Propulsion_eBox

As far as AC, you might check the thread just under yours, on Calmotors. Someone there claims to have gotten a quote from them. I don't know of anyone who has actually purchased one though. Metric Mind in the U.S. carries some higher power AC motors, EV Propulsion would do the job, but they don't seem to sell to individuals, only OEMs. You might find a used Ford/Siemens motor like Etisher used in his VW Passat (see his build thread), but you will then need a controller for it. Those are the only sources I know for higher power AC motors, I expect you may need to use DC for the amount of power you want, due to the difficulty in obtaining a higher power AC motor/controller. If you want to drive 160 miles, and I'm guessing at freeway speeds, you will need a very large pack of LiFePO4 cells. I would guess around 50 kWh, depending on final weight and drag force of your vehicle.

Tom,
Thats AC propulsion that has AC drive systems, we at EV-propulsion do sell to individuals, but are DC system vendors and converters, although we would do AC systems if a suitable and cost effective solution was out there....

 75kW Peak, 42 cont. power
 100-360VDC Input Range
 754.79 Nm peak torque
 99% efficiency
 Microprocessor-controlled inverter
 Friendly Graphical user interface
 Regenerative Braking
 Small, lightweight inverter/controller
 Fully functional as HEV, or EV system
 Water cooled AC induction motor
 Dual CAN 2.0B for heavily automated vehicles
 Boot Loader for field upgradable firmware
 Industry standard sensor interfaces to monitor the vehicle
 Extensive analog and digital I/O
 Induction and Synchronous motor options

Mike,
which siemens/ford motor is it?

[EV-propulsion.com]

It is the 5133ws20, used in the ford ranger pickup. I am not sure of the difference between 5133 and 5134, I will try to do some research...unless somone here knows...
