A guide to planning EV charging infrastructure including CSMS selection, build vs buy decisions, RFP requirements, NEVI compliance, and long-term cost and scalability planning.

Learn how EV charging networks are architected, including the role of CSMS platforms, OCPP communication, payment systems, and roaming infrastructure.

Learn how open standards like OCPP, OCPI, and ISO 15118 enable interoperable EV charging networks and how platforms like CitrineOS and TopazEV support scalable infrastructure.

EV charging payments are more complex than traditional transactions. Learn how charging networks manage billing, pre-authorization holds, pricing models, and payment infrastructure.

EV charger downtime is rarely caused by hardware alone. Most failures stem from communication issues, software limitations, power constraints, or device firmware conflicts. This article explains the most common causes of charging network downtime and how operators diagnose and improve reliability across large EV charging deployments.

Electric vehicle charging infrastructure depends on more than hardware. Behind every charging network is a software platform responsible for managing devices, coordinating charging sessions, processing payments, and ensuring network reliability. This software layer is commonly referred to as a Charging Station Management System (CSMS). As EV adoption grows globally, CSMS platforms have become one of the most critical components of charging infrastructure. This guide explains how EV charging software platforms work, the technologies they depend on, and the factors operators consider when choosing a platform.

EV charging sessions involve authentication, pricing, and settlement across multiple parties, making them closer to financial transactions than utility services. This article explores why payments and identity are becoming central to charging infrastructure, how Plug & Charge and programmable payments change backend responsibilities, and why open charging platforms give operators greater operational and economic control.

As EV adoption accelerates, car dealerships are discovering a powerful new profit center: EV charging. In this commentary featured in Motor Trade News, S44 Energy CEO Olga Haygood shares how smart software strategies and open infrastructure can help dealerships turn charging into a scalable, customer-focused revenue stream.

Explore how dynamic pricing strategies could revolutionize electric vehicle charging networks by balancing operator margins, grid load and user satisfaction. In this guest commentary, CEO of S44 Energy, Olga Haygood breaks down the case for smart, real-time pricing models that adapt to demand, energy costs and station utilization—enabling scalable, reliable charging infrastructure.

Discover how open-source EV charging software like CitrineOS and TopazEV is transforming Charge Station Management Systems (CSMS). Learn why flexibility, transparency, and interoperability are key to scaling global EV infrastructure.

S44 Energy has launched TopazEV, the industry’s first Open-as-a-Service (OaaS) charge station management software (CSMS). Designed for charge point operators, fleets, retailers, and utilities, TopazEV eliminates vendor lock-in and per-session fees, providing operators with scalable, protocol-compliant control over their EV charging networks. Supporting OCPP 1.6, 2.0.1, OCPI, and ISO 15118, TopazEV offers real-time dashboards, intuitive UI, and seamless API integrations. Available via hosted subscription or business source license, TopazEV helps democratize access to reliable, open EV charging infrastructure.

Olga Haygood is the CEO of S44 Energy, a software company that solves the real-world problems behind EV charging infrastructure. Her team created a widely adopted open-source project, now hosted by the Linux Foundation, as well as the industry’s first Open-as-a-Service charge station management software. She is deeply engaged in advancing democratization and standardization across the industry. In this Q&A, Olga explains what’s holding the EV industry back and what it will take to future-proof public charging networks worldwide.
