S44, custom EV software solutions company, announced the open-source project CitrineOS.

CitrineOS delivers critical 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.

Based on real-world EV charging use cases and the need to improve reliability, the modular software enables widespread interoperability between charging equipment, vehicles, and networks and is available worldwide.

‍Complying With OCPP 2.0.1 Standards

The Biden administration's goal for 2030 includes establishing 500,000 public EV chargers and achieving a 50% market share for electric vehicles.

However, the inconsistent and unreliable charging experiences deter consumers from fully embracing this vision.

Even in cities with high levels of EV adoption, the operational rate of fast charging stations stands at just 72%, falling short of the 97-99% uptime needed to secure federal funding.

Under the Bipartisan Infrastructure Law, President Biden has allocated $7.5 billion for EV charging infrastructure, while the Charging and Fueling Infrastructure discretionary grant program offers an additional $2.5 billion in funding.

To be eligible for this financial support, EV charging management software must comply with OCPP 2.0.1 standards by February 28, 2024.

‍“Even with an experienced team, you’re looking at six to eight months to build NEVI-compliant EV charge management software from scratch,” said Julian Offermann, co-founder and CEO of S44. “With CitrineOS, you can do it in a month. Democratizing access to the software is the only way to be fast enough to hit the state and federal certification deadlines.”

CitrineOS is now available on GitHub

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

• Provision 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,” said Cliff Fietzek, board member of CharIN North America. “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.”

‍CitrineOS enables industry-wide collaboration on a single code base. The ability to build and apply fixes for broad use will make back-end communication more reliable across the board.
