A modular monolith architecture for high-availability electric vehicle charging station management software

The article presents the results of research and development of a highly available, fault-tolerant software system for managing electric vehicle charging stations. The proposed solution is based on a modular monolith architecture, which combines ease of implementation and maintenance with the ability to scale under increasing load. An analysis of the current state of charging infrastructure, architectural approaches, communication protocols (in particular, OCPP with WebSocket), and reliability-enhancing technologies such as containerization and message brokers is provided. The implemented functional modules of the system are described. The results of the experimental study confirm the system’s stability and efficiency under high load conditions and demonstrate its readiness for deployment in a real-world environment.
