Mofiu Unveils SG100 Industrial 4G Router to Power Always‑On Connectivity for EV Charging Stations
Guangzhou China — Mofiu, a leading manufacturer of industrial wireless communications equipment, today announced the SG100, a rugged 4G router engineered to deliver secure, reliable, and resilient connectivity for electric vehicle (EV) charging infrastructure. With dual‑SIM cellular, versatile I/O, and advanced security built in, the SG100 provides the robust communications backbone operators need to scale charging networks with confidence.
“EV charging networks demand carrier‑grade uptime and industrial‑grade security in some of the harshest deployment environments,” said a Mofiu product manager. “The SG100 was purpose‑built for that reality—combining dual‑SIM redundancy, flexible interfaces for charger and site controllers, and hardened security from boot to tunnel.”
Built for the Edge: Reliability, Redundancy, and Reach
Dual‑SIM 4G LTE with intelligent failover ensures continuous service across carriers and coverage conditions—crucial for payment authorization, session telemetry.
Two Ethernet ports allow flexible LAN/WAN topologies, including back‑to‑back edge segments for chargers, payment kiosks, and energy management systems.
RS232 and RS485 serial ports bridge legacy and modern equipment—ideal for interfacing with charger controllers, PLCs, meters, or site gateways.
One digital input and one digital output enable event‑driven automation and remote control (e.g., alarms, cabinet door sensors, relay triggers).
Wide 9–48 VDC input simplifies power integration with site supplies and DC systems; extended operating temperature of −40 to +75 °C supports outdoor enclosures and challenging climates.
Secure by Design, from Power‑On to Payload
Secure Boot at the hardware and software layers verifies firmware integrity before the system initializes—helping prevent tampering and unauthorized images.
Multi‑protocol VPN support (e.g., IPsec, OpenVPN, WireGuard) protects data in transit, enabling encrypted tunnels to cloud backends, payment processors, and central management.
Granular link and route management ensures deterministic failover, preferred‑path selection, and bandwidth utilization across cellular and Ethernet links—keeping chargers online when it matters most.
Optimized for EV Charging Station Operations
Uptime for Transactions and Telemetry: Dual‑SIM resilience maintains continuous connectivity for payment flows, session records, diagnostics, and software updates—supporting high service availability and customer satisfaction.
Flexible Integration: Ethernet plus RS232/RS485 connect to charger controllers, smart meters, and building energy systems, while DI/DO lines enable field automation and alerting.
Edge‑Ready Security: Encrypted tunnels and hardware‑verified boot sequences help safeguard sensitive payment and user data as well as operational control traffic.
Scalable Rollouts: Compact form factor, broad input voltage, and extreme‑temperature tolerance streamline deployment across curbside, depot, commercial, and highway charging sites.
