Explore our highly robust, commercial-grade DC & AC charging solutions, engineered for maximum uptime and seamless payment integration.
As the global automotive industry undergoes a paradigm shift toward electrification, Charge Point Operators (CPOs), fleet logistics networks, and real estate developers face critical scalability bottlenecks. Reliable cellular IoT communication acts as the nervous system of modern EV charging networks. 4G connected charging stations represent the golden standard for network resiliency, enabling zero-latency payment processing, real-time dynamic load management, and persistent OTA (Over-The-Air) telemetry.
Leveraging LTE Cat 1, Cat 4, and NB-IoT fallback configurations, our premium 4G connected charging solutions bypass the localized physical failures common to Wi-Fi networks and avoid the astronomical wiring expenses of Ethernet systems. Engineered in our state-of-the-art Chinese manufacturing facilities, these stations integrate seamless hardware-to-cloud security, guaranteeing unmatched service reliability in urban commercial centers, highway corridors, and complex sub-grade parking environments.
Greenvora adheres to the technical enterprise, scientific research, design, manufacturing, sales and service in one. We specialize in providing system energy solutions for customers.
How 4G telemetry mitigates grid peak demands and optimizes localized power allocation.
By connecting to smart meters via 4G cellular links, our stations adjust output power in real-time, preventing electrical overloads across commercial facilities without requiring expensive grid capacity upgrades.
Seamless connection to any generic backend management platform globally. Our native OCPP integration supports secure WebSockets over TLS, ensuring remote configurations, diagnostics, and firmware rollouts remain fully protected.
Future-ready bidirectional power transmission routing. Our charging units incorporate the control circuitry needed to feed power back to the grid or facilities during peak utilization times, yielding monetizable benefits.
With the independent development ability of charging master, Fonsencharge can provide customized core master control board for charging pile enterprises. At the same time, the company has formed cooperation with dozens of large charging pile related enterprises at home and abroad in the ODM field and achieved excellent results.
Our strength lies not only in structural assembly, but also in core technology development. Through our dedicated engineering division, Fonsencharge, we design and manufacture the highly advanced smart control boards that govern entire charging systems. This vertically integrated development paradigm guarantees that our 4G connected hardware features deep firmware optimization, direct diagnostic telemetry, and multi-network protocol configurations.
Through extensive strategic partnerships, we have delivered dozens of customized turnkey solutions to Tier-1 operators in North America, Europe, and Asia. Our deep OEM/ODM service suite includes customized hardware design, customized OCPP backend routing, integration of localized payment terminals, and comprehensive electrical safety engineering for compliance with domestic power grids.
Tailored hardware configurations designed to satisfy distinct operational environments.
Features embedded payment terminals, clear interactive LCD touchscreens, and dynamic advertising delivery. The robust 4G uplink guarantees instantaneous credit card, RFID, and Apple Pay payment validation, maximizing site revenue.
Configurable for continuous high-amperage output with liquid-cooled cables. Integrated software platforms coordinate with fleet logistics management software via 4G API hooks to prioritize charge distribution based on scheduled vehicle shifts.
Our floor-mounted and wallbox chargers provide smart power balancing, enabling multiple tenants to charge simultaneously. Fully automated billing splits energy costs precisely between tenants using encrypted RFID cards or mobile apps.
Entering international charging markets demands strict compliance with diverse safety and metrological standards. Our headquarters operates under strict ISO9001 quality system management and has obtained premium global certifications, including DEKRA CB, CE, and ISO9001 high-tech enterprise classifications. These credentials verify that our equipment meets the strictest international electrical safety and electromagnetic compatibility standards.
Additionally, we have earned 15 software copyrights and several utility and design patents. For European markets, we offer systems compliant with the Measuring Instruments Directive (MID) and German Eichrecht calibration requirements, ensuring transparent, legally compliant kWh-level billing transactions for public operators.

Detailed answers to complex questions regarding connectivity, electrical engineering, and customization.
A: Wi-Fi networks in public and semi-public environments are prone to interference, credential expirations, and range limitations, while Ethernet cabling demands expensive trenching and wiring. Integrated 4G (with NB-IoT fallback) offers dedicated cellular bandwidth directly from regional telecom towers, providing independent operational connectivity. This configuration is essential for processing secure transactions and ensuring continuous telemetry for remote management platforms.
A: No. Our custom-designed control boards feature built-in offline queue storage. If the 4G signal drops, transactions are authorized locally via encrypted RFID profiles, with transaction logs securely cached inside the charger's non-volatile memory. Once connection is restored, the cached data is automatically synchronized to the OCPP backend. This mechanism prevents service disruptions and protects operator revenue.
A: Yes, structural design and custom software optimization are core strengths of our manufacturing model. Through our Fonsencharge master control board development team, we can customize parameters such as OCPP custom fields, dynamic charging profiles, custom billing display fields, and unique diagnostic telemetry reporting intervals, guaranteeing seamless compatibility with your proprietary management system.
A: Absolutely. We manufacture chargers with all globally recognized charging interfaces, including CCS1 (North America), CCS2 (Europe), CHAdeMO, GB/T (China), and the recently standardized NACS (Tesla/SAE J3400). Our systems utilize universal communication protocols (DIN 70121, ISO 15118) to ensure smooth handshake processes with electric vehicles globally.
