Uniting EV CPOs and Enthusiasts
Unlike proprietary EV charge management software, our S44 CSMS gives everyone a common platform to build reliable and resilient EV charging networks.
Modular Software
Unlock the full potential of S44 CSMS, whether you choose to use it as a standalone solution or build upon its capabilities to effortlessly provision and remotely control chargers, facilitate seamless transactions, monitor uptime, power levels, and degradation, and efficiently manage consumption and throughput.
OCPP 2.0.1 + NEVI Compliant
By being Open Charge Point Protocol (OCPP) 2.0.1 compliant, National Electric Vehicle Infrastructure (NEVI) compliant, and offering the potential to qualify for $10B in funding, our solution not only meets industry standards but also future-proofs charging networks.
Open-Source Foundations
Building on top of the open-source project, CitrineOS - authored by S44 and adopted by the Linux Foundation Energy, not only reduces runtime and operational costs but also leverages a cloud micro-services architecture, enabling widespread interoperability and enhancing overall system reliability.
