As a manufacturer, you don’t just deliver hardware – you deliver reliability. And that reliability depends on the communication inside the charging station.
A stable and secure connection is essential: for manufacturers to enable efficient diagnostics and maintenance, for operators to ensure reliable billing processes, and for end users to experience uninterrupted charging.
Without this connection, faults remain undetected, service interventions increase, and in the worst case, billing data is lost. A robust communication layer, by contrast, creates transparency, security and long-term product quality.
Reliable, secure connectivity as the foundation of every charging point
Fewer service calls thanks to remote diagnostics
Scalable management for growing charging fleets
Challenges
- Invisible faults: Without a continuous connection to the backend, internal defects – such as in power electronics or sensors – remain undetected until complete failure occurs.
- High service costs: Every on-site intervention is time-consuming and costly. Poor planning and logistics reduce margins.
- Scaling complexity: As the number of deployed charging stations grows, managing routers across the fleet becomes increasingly complex.
- Reputational risk: Frequent failures reduce operator trust, damage brand reputation and negatively impact the end-user experience.
- Security in payment processes: Communication between charger, payment terminal and backend must be protected against manipulation and unauthorised access.
- Outdoor conditions: Routers inside charging cabinets are exposed to significant temperature fluctuations that can affect communication stability.
Solution
- Remote diagnostics & predictive maintenance: The router provides stable, secure connectivity and delivers system and communication data for analysing charger behaviour. This enables remote monitoring, early fault detection and proactive service planning.
- Targeted maintenance: Service interventions become predictable, as technicians can identify the root cause in advance and arrive with the right spare parts.
- Centralised and scalable router management: Firmware, configurations and feature updates can be deployed centrally over the air (OTA). Thousands of routers can be monitored and managed through a unified platform.
- Maximum availability through redundancy and self-monitoring: Hardware and software watchdogs detect faults automatically. Redundant communication paths (e.g. dual SIM or multi-WAN) ensure continuous connectivity.
- Secure payment communication: Encrypted communication (TLS/IPsec) and certificate-based authentication ensure secure transmission of billing and payment data and support compliance requirements.
- Temperature resilience for outdoor operation: Industrial-grade routers with extended temperature range (–40 °C to +75 °C) ensure stable operation inside charging cabinets – even under extreme conditions.
