Im an automotive engeering student and i have a project to make a EVSE for the school, that charges with 3-phase and uses type-2 Mennekes plug.
Im suppose to use these parts with the Arduino Uno:
Contactor: GE 666151, 4P, 40A, 415V~, Uc:230V
RCD: GE 693467, 4P, 40A, 240/415V~, 30mA
RCM (for 6 mA DC fault current detection): Phoenix Contact EV-RCM-C1-AC30-DC6
Type-2 Plug from Phoenix Contact
I was wondering can i build the arduino shield with these instructions:
and still use 3-phase charging and type-2 Mennekes plug.
If i can, what firmware you would suggest to be used, since i dont use LCD screen only LED. What kind of changes would i have to do to the program code that there would not be LCD screen, GFCI and it would use the electric lock of the type-2 socket to the plug?
What would be the differences with the wiring?
We do not recommend or support using the Arduino Shield. It does not have any of the required safety features and was intended for basic software development only.
A setup with the arduino shield should NEVER be used for actual charging of an EV. It was intended to see a maximum of 5v via a USB connection, for development of firmware only.
We would highly recommend starting your project from a much newer controller design with the appropriate safety features.
