Practical Knowledge for Building and Operating EV Charging Networks
• Clear explanations of standards and workflows •
Proven charging network architectures
• Procurement insights for reliable deployments
Understand why chargers fail, how uptime is measured, and what affects real-world reliability.
- Charger offline causes
- Session failures
- Firmware compatibility
- Network monitoring
- Reliability metrics
EV charging is not a traditional retail transaction. Charging sessions require pre-authorization, time-based billing, and complex settlement workflows.
- Credit card failures
- Tap-to-pay terminals
- Pre-authorization holds
- Idle fees
- Payment gateways and settlement
Charging networks depend on communication protocols. Understanding them is critical for interoperability.
- OCPP 1.6 vs 2.0.1
- OCPI roaming
- Plug & Charge (ISO 15118)
- Security profiles
- Hardware interoperability
How backend software, chargers, and external systems integrate into a working ecosystem.
- CSMS architecture
- Hardware-agnostic networks
- Load management and smart charging
- Integrating new charger models
- Scaling networks
Guidance for organizations deploying or
expanding charging infrastructure.
- Selecting a CSMS platform
- Build vs buy decisions
- RFP requirements
- NEVI compliance considerations
- Cost and scalability planning
Built from real charging networks
The systems described in these guides reflect real architectures used in production charging networks built by S44 Energy.
Organizations planning deployments often use these resources when evaluating operational readiness and software strategy.
S44 Energy
S44 Energy develops EV charging software platforms based on open standards including OCPP, OCPI, and ISO 15118. Our solutions support public charging, fleet electrification, and utility infrastructure programs. We build both custom charging platforms and managed charging operations software designed for scalable deployments.
