Ensuring High-Availability Connectivity for Distributed EV Charging Infrastructure
Customer Profile:
A Global System Integrator of Smart Public EV Charging Networks
The Challenge: Network Volatility and High Maintenance Costs
As the global transition to electric mobility accelerates, charging network operators face the immense challenge of maintaining infrastructure across highly dispersed locations. From sun-baked highway rest stops to damp underground parking garages, charging pedestals must remain online 24/7. The integrator previously used commercial-grade networking equipment, which frequently suffered from thermal throttling in extreme weather. When a charging station loses its network connection, it cannot authorize user payments or report hardware faults. Sending technicians on-site to simply manually reboot frozen routers was driving up operational and maintenance (O&M) expenditures to unsustainable levels, severely impacting the operator's profitability.
The Solution: Deploying the MOFIU SG100-4G as the Resilient Communication Core
To overcome these critical bottlenecks, the integrator standardized their charging pedestal designs around the MOFIU SG100-4G Industrial Secure Gateway (Model: SG100-4A40), leveraging its standalone hardware robustness.
Intelligent Auto-Recovery Mechanisms: Operating independently of any external systems, the SG100 ensures maximum uptime through its built-in Hardware Watchdog and RTC (Real-Time Clock). If the 4G LTE connection experiences a carrier-level stall, the hardware automatically executes a localized soft or hard reboot sequence to restore the connection, completely eliminating the need for manual, on-site intervention.
Industrial-Grade Environmental Tolerance: The SG100 is engineered from the ground up for extreme conditions. Its compact footprint ($108mm \times 90mm \times 36mm$) easily integrates into tight charging cabinets. Powered by a highly stable 9-48 VDC power input, the gateway integrates seamlessly into the high-voltage electrical environment of the charging station, remaining completely immune to power sags and surges that typically destroy commercial routers.
Secure Payment Transmission: Utilizing the Stateful Firewall, MAC/IP Filtering, and robust OpenVPN tunneling protocols embedded in the firmware, the SG100 ensures that all user payment data is heavily encrypted before it leaves the physical charging cabinet, protecting against interception and ensuring data privacy compliance.
The Benefits: Maximized Uptime and Drastically Reduced O&M Costs
The SG100's self-healing connection mechanisms virtually eliminated connection-related station downtime. By relying on automated hardware watchdogs rather than manual resets, the network operator reduced physical maintenance dispatches by over 60%, drastically cutting associated labor and travel expenses while guaranteeing a seamless charging experience for EV drivers.
