Arduino code for a super simple EVSE, intended for development use only.
- Generates the Control Pilot signal and responds to EV connection
- Very Very simple code
- Very Very simple hardware
- Use at own risk
- No GFI
Based on https://www.instructables.com/Arduino-EV-J1772-Charging-Station/
Uses a cheap +-12v DCDC module and an OPAMP.
Control Pilot Signal Components

- P6KE16CA bidirectional TVS diode
- 1% 1k ohm resistor
- 100k ohm resistor * 3
- 56k ohm resistor
- 200k ohm resistor
- +12 & -12v power supply module
