OpenEVSE

OpenEVSE is an Arduino-based electric vehicle charger created by Christopher Howell and Sam C. Lin.[1] The charger is composed of open-source software[2] and hardware which can be made DIY.[3]

History

The project started in February 2011[4][1] with a simple experiment to try to generate the SAE J1772 pilot signal[5] on an Arduino-compatible ATmega328 8-Bit AVR MCU.[6] One experiment led to another until a prototype J1772-compatible controller was born. What started as six boards built in the first batch turned into many thousands. Today, OpenEVSE powers charging stations from many manufacturers all over the world.[7]
