Homemade 100 HP Motor Controller for an Electric Car


 by 

This instructable explains how to build your own 100 HP (peak) motor controller for use in an electric car or 
motorcycle conversion.  It can take any voltage up to 144v, and the peak current is 500 amps.  The cost of
 the components is a few hundred dollars, which means you can save over $1000 by putting one together 
yourself.   At 144v, you can expect a top speed of around 75 MPH in a car.

if you want to read about the whole story!

Experience in soldering is important.  If you want to really keep costs down, a mill is helpful, but that work
 can be outsourced to a local metal shop.


You are going to need a control board and etched power board.  The power board needs to be at least 3 ounce copper.   Ebay is a good place to look for heavy cheap copper clad PCB.  For example:

You could print the picture from this link and somehow transfer it onto a piece of heavy blank PCB, and etch it with a dremel if you have a ver y steady hand.  The dimensions are 8"x6".  This link also has the G-code that you can use to etch with a CNC mill or you could give the G-code to a machine shop.

Picture 2 and 3 below is an example of an early power board I made with a Dremel.

You can get a control board from me or you can make the control board in your favorite PCB layout software using the schematic here::

And here are some pictures of the PCB layers:

    Projects

    I really enjoy working on projects. Much of what I do is software oriented, but I also enjoy electronics and other hands-on opportunities.
  • Software projects
  • Hardware projects
  • Other projects - such as hybrid hardware & software projects, or even completely non-technological projects

To-Do List

Here is a list of projects that I want to do, some are partially implemented as proof-of-concept, while others are mere ideas:
Repository management system. Needs to handle: git, hg, svn, cvs, fossil, etc... Provide simple mirroring and update features, etc...
Plant pot water level sensor. Raises an alarm when the plat needs watering - perhaps even one day turn on a tap too??
Pulse Oximeter. I've always liked the idea of developing medical equipment, this sounds easy, and I'd like to have one!
Smart PC Power Control/Monitor. I've got a basic power control and monitor setup for my PCs, but I'd like to develop this to a less prototype-esque state. Key features are remote power state monitor and control, and remote reset. The module acts like physical switches and runs on it's own... sort of like HP's iLO and Dell's DRAC, but as a retro-fit accessory.

Atmels ATmega48 (or ATmega88 for smarter ones) that does all the work. For some weird reason Chinese manufacturers LOVE ATmega48, it is in every design. Like always it is clocked at 16MHz with resonator. AVR in this design is in QFN package, in most of the cases TQFP is more common.5V voltage regulator in D-pack and some ceramic capacitors.Maxim MAX662 12V 30mA charge pump for high side gate driving. The output of the charge pump is stored on the ceramic capacitor on the right.
International Rectifier IR2101S high and low side mosfet driver. One for every channel. On the right of every driver there is a diode and a capacitor. This is probably bootstrap circuit that collects higher voltage for gate driving from inductance spikes of outputs.
In between of gate drivers are resistors for feedback.
The top part is for BEC. It looks identical to very common switching regulator block used in ebay products. Texas Instruments LM2575, originally a 1A step-down but now apparently a 5A one.
