the powerful foundational
EV charging platform
An important milestone
A game-changer for CPOs and
specialised software solutions
The HARMON-E platform offers a stable, future-proof foundation for Charge Point Operators to connect, control, and monitor their EV charging networks. It supports all major protocols, driving innovation and ensuring standardization across the e-mobility ecosystem
With an OCPP-based broker and vendor-independent architecture, HARMON-E enables seamless integration of charging stations, energy resources, and third-party applications—delivering real-time data exchange and the flexibility to scale without limitations or lock-in.
The challenges for CPOs
Overcoming the complexities
of scaling EV charging networks
Managing and scaling a diverse network of EV charging stations can be complex for Charge Point Operators. Operators often face difficulty integrating multiple Charge Point Management Systems (CPMS) and third-party applications, which limits their ability to access real-time data and creates operational inefficiencies.
Vendor lock-in presents another challenge, making it costly and disruptive to switch between CPMS providers. Additionally, as networks grow, integrating new hardware and software becomes more complicated, adding further complexity to scaling operations effectively.
The Solution
The HARMON-E Platform
and its key components
The platform is built around three core elements:
Data brokerage
HARMON-E provides set points accessible via API and MQTT, including OCPP data and DER data such as power meter readings, battery metrics, and solar panel information.
Intuitive UI
The platform centralizes data, configurations, and control into one intuitive panel, allowing you to manage all charging infrastructure, including batteries and solar energy.
System Health
Charging Analytics helps CPOs monitor site data and detect anomalies for maximum uptime. Alerts notify CPOs of critical events in real-time via HARMON-E, email, or API, ensuring control over operations.

Benefits
Benefits for CPOs
Built around an OCPP broker, HARMON-E seamlessly connects charging stations, distributed energy resources (DER), and third-party systems, providing real-time data exchange and streamlining operations.
Independence and Reliability
HARMON-E uses highly available OCPP endpoints that work independently of any CPMS, ensuring seamless integration and robust connections. Each charging station has a dedicated broker, offering superior reliability and performance through a distributed architecture.
Seamless integration with 3rd party services
HARMON-E simplifies integration of third-party SaaS solutions like predictive maintenance and scheduling. It supports flexible API strategies and is compatible with OCPP standards (1.6 to 2.0.1), ensuring future-proof flexibility.
Hardware flexibility and simplified management
HARMON-E’s broker enables smooth OCPP communication, streamlining operations with batch management of charging stations. A single Websocket URL simplifies configuration and ensures consistent performance across all chargers.
Centralised data storage and access
The platform includes a central data sink independent of the CPMS, ensuring high data quality. All data is consolidated for easy access, analysis, or integration with third-party software, providing a consistent source of truth for your operations.
Efficiency, flexibility, and cost savings
HARMON-E captures real-time data like connection statuses and errors, helping you resolve issues before they affect your business. Its open platform supports third-party solutions and simplifies CPMS switching by updating the Websocket URL. Optimized for energy use cases, HARMON-E reduces costs and complexity compared to full CPMS systems.
