OpenEVSE (Electric Vehicle Supply Equipment) is an Arduino-based charging station created by Christopher Howell and Sam C. Lin.[https://store.openevse.com/pages/about-us OpenEVSE About page] The charger is composed of open-source software[https://github.com/OpenEVSE OpenEVSE at github] and hardware that can be made by individuals.[http://openevse.dozuki.com/Guide/OpenEVSE+50A+Charging+Station/8 Software and hardware needed to build the OpenEVSE charger]

The project started in February 2011,{{Cite web|url=http://www.mynissanleaf.com/viewtopic.php?t=2736|title=Weekend(s) Project - DIY EVSE|date=15 February 2011|website=My Nissan Leaf Forum|access-date=2019-09-09}} with an experiment aimed at generating the SAE J1772 pilot signal{{Cite web|url=https://openalia.wordpress.com/tag/openevse/|title=openEVSE - openalia|language=en|access-date=2019-05-01}} 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.{{Cite web|url=https://www.macrofab.com/podcasts/electric-vehicle-charging-and-cat-safety/|title=MEP EP #162: Electric Vehicle Charging And Cat Safety MacroFab Engineering podcast|date=2019-03-06|website=player.fm|language=en|access-date= 11 Jun 2024}}
