Whatever 3A or 5A diode will do. I am just using it to be foolproof against idiots like me who want to connect power in reverse :). Added benefit is diode drops the voltage a bit so arduino regulator doesnt see too high voltage. Very helpful thanks! I've populated your shield programmed the Due and...

Yes i designed the board to use any CAN or PWM control charger. Diode is there for the time a moron(me) connects 12V in reverse. And it is just a power diode. Its voltage drop keeps the DUE 5V regulator safe, since a car battery is more than 12V. I included a regulator in case i needed it... Hi, tr...

Testing success! I couldnt let it rest and i connected charger AC lines via some fastons. I connected HV to my test battery and LV control connector to 12V and my PWM pulse generator. I got good steady 9A of charging at 366Vdc! Control is really simple 100Hz with duty 25% to 90% varying current at ...

Diode is there for the time a moron(me) connects 12V in reverse. Ha it happens for everyone sometimes so better to safeguard against such incidents of course! Do the specs of that schottky matter or any does the job? And it is just a power diode. Its voltage drop keeps the DUE 5V regulator safe, si...

What i use in my car is Arduino DUE module and my own shield with inputs and outputs suitable to CAN bus, relay and PWM connection. DUE uses PWM pins which you can drive using analogwrite() function and make it variable :). Here is my DUE shield with history: https://github.com/arber333/Arduino-Due...
