OpenEVSE

OpenEVSE (Electric Vehicle Supply Equipment) is an Arduino-based charging station created by Christopher Howell and Sam C. Lin.^[1] The charger is composed of open-source software^[2] and hardware that can be made by individuals.^[3]

The project started in February 2011,^[4][1] with an experiment aimed at generating the SAE J1772 pilot signal^[5] on an Arduino-compatible ATmega328 8-Bit AVR MCU. Subsequent experiments continued until a prototype J1772-compatible controller was created. As of now, OpenEVSE powers charging stations all over the world.^[6]
