I have a BS in Electronic Technology with equipment and get the theary and concepts. I do not have your valuable experience. Your huge threads are difficult to process easily. I have converted 8 cars cheaply and my 20A chargers cost about $10 by using just a full wave bridge.

Your 500A to 800A controller is to complex to troubleshoot readily. If I had measurements (V) of the micro processor inputs and outputs under success and different failures, then I could troubleshoot the simple circuits left.

I have built a 1000A controller using your power driver and fets with diodes. I have bought a cheap PWM control to drive it. I will use smaller wire resistance to current limit at first. I still have to find a simple current limit cricuit to connect to the driver chip. I have upgraded your fets and diodes and mounted them on big heat fins with a fan for supperior cooling. This contoller costs under $200 in parts. I do understand the dire need for your additional complexities and computer. I know I will be blowing some stuff up but hope that you can reduce the failures.
