You can find the electric motor controller schematics and bill of materials there. A special thank you goes to Ecomodder and all those that has helped us put this wiki together.




EV Motor Controller (rev 2C) Specs.

1. High Pedal Lockout (the controller won't start if the accelerator is pressed down)

2. Cycle by cycle hardware overcurrent protection

3. Low voltage controller disable (if the control section power supply drops too low, the mosfet driver is disabled)

4. Controller accepts any pack voltage in the range of 0v up to 144v nominal. 0v won't have a very high top speed. :)

5. Throttle is proportional to current. No jerky starts. Very smooth operation at any speed.

6. It's not yet known how long the controller can run at a given current before the thermal cutback starts to kick in. There is a video of the controller running at around 200 amps for about 20 minutes in Phoenix during July, where the ambient temperature was around 108 degF.

7. There is temperature cutback, starting at around 75 degC.

8. More features coming in the next few days. Lots of software improvements. Reprogrammability.
