S44, an e-mobility, automotive and energy software solution company, announced an open-source project CitrineOS, now available on GitHub. CitrineOS delivers back-end software required to quickly stand up EV charge management compliant with Open Charge Point Protocol (OCPP) 2.0.1 and National Electric Vehicle Infrastructure (NEVI) standards, S44 said. Based on real-world EV charging use cases and the need to improve reliability, S44 said the modular software enables widespread interoperability between charging equipment, vehicles and networks and is available worldwide.

S44 said everyone from enthusiasts to the largest global charge point operators, fleet managers and car manufacturers can use CitrineOS to:

• Provision of new charging equipment;
• Complete charging transactions;
• Remotely control charging equipment;
• Monitor charger equipment uptime, power levels and degradation;
• Manage energy consumption and throughput.

“Reliable, standardized and open back-end communication is key for commercial, fleet, public and autonomous electric vehicle charging infrastructure,” Cliff Fietzek, board member of CharIN North America, said. “CitrineOS is a game changer for this communication, built natively on the latest charge point protocol standard, OCPP 2.0.1. Now anyone can leverage the open source libraries to get to work quickly — to bring even legacy networks to OCPP 2.0.1 compliance.”
