Engineered to international standards with OCPP integration, high safety topologies, and scalable power capacities.
As the global transition to electric transportation accelerates, high-power DC fast charging has emerged as the cornerstone of utility-scale EV implementation. Among the dominant global interfaces—CCS1, CCS2, CHAdeMO, and GB/T—the GB/T (Guobiao) standard represents one of the most widely deployed charging architectures in the world. Originally defined to support the vast and rapid expansion of electric vehicles in mainland China, GBT DC Chargers are increasingly utilized in international corridors, special trade zones, and key regions including Central Asia, Southeast Asia, South America, and Eastern Europe.
Wholesale buyers and infrastructure developers require robust, highly efficient GBT DC chargers that offer seamless integration with localized grids. Modern GBT charging stations are engineered with multi-standard interoperability in mind, utilizing dual-nozzle designs (e.g., GBT + CCS2) and advanced software communication protocols to service diverse fleets.
Engineered for next-generation 800V and 1000V electric vehicle architectures, reducing heat loss while minimizing charge duration under peak conditions.
Allows continuous output rates up to 500A without thermal degradation, maintaining physical ease of use and flexibility for terminal operators.
Intelligently divides output power among active charging guns depending on real-time vehicle battery management system (BMS) queries.
A certified National High-Tech Enterprise pioneering smart charging solutions and sustainable power supply systems worldwide.
Tongxing integrates robust industrial infrastructure with modern manufacturing principles. Our 72,000 square meter production center houses state-of-the-art SMD lines, transformer winding stations, and climate-controlled assembly areas achieving a 95% production automation rate.
We maintain a dedicated workforce of over 200 specialists: 140+ certified technical operators, 20+ power electronics and embedded systems engineers, and a 40-member internal Quality Assurance team conducting rigorous audits under ISO 9001, ISO 14001, and ISO 45001 frameworks.
Analyzing supply-chain velocity, raw material access, and technological scaling advantages.
Chinese manufacturers operate at the epicentre of the global lithium battery and copper supply chain. From key raw materials to final semiconductor assembly, domestic factories eliminate long lead times and high import duties on components, translating directly into competitive pricing structures for international procurement agents.
With massive R&D resource pooling, Chinese factories can prototype, certify, and optimize new hardware iterations in weeks rather than months. Customizations for white-label requirements, cabinet paint finishes, custom OCPP endpoints, and specialized payment modules are completed with exceptional speed.
Elite export-oriented factories undergo independent TÜV Rheinland, CE, and RoHS audits. High-precision testing chambers simulate marine corrosion, extreme high/low temperatures, and dynamic seismic events, ensuring that final shipments arrive ready for long-term field installation under hostile climates.
The modern energy transition demands more than standalone chargers. Tongxing delivers full-scenario energy ecosystems combining high-efficiency photovoltaic power generation, modular lithium iron phosphate (LiFePO4) energy storage, and ultra-fast DC charging piles.
Solar panels mounted on carports and rooftops capture ambient sunlight, feeding clean energy directly to connected EVs. This onsite generation meets 30% to 50% of peak operational demand, slashing electricity costs to 1/3 of standard utility grid pricing.
High-voltage cascaded LiFePO4 batteries (from 100kWh to 10MWh) capture low-cost electricity during off-peak hours and release it during peak-tariff windows, reducing operational utility expenses by up to 40% and preventing localized grid overload.
An intelligent energy management system (EMS) tracks solar forecasting, battery state-of-health, and charger consumption in real-time, executing automated economic dispatch schedules to maximize ROI.

How dynamic fleet operators and municipal grids utilize high-performance GBT DC charging configurations.
Logistics fleets require ultra-fast turnaround times. Utilizing GBT DC chargers rated from 120kW up to 360kW, operators can charge delivery vehicles during driver break shifts. Modular power cabinets ensure that if one charging module requires service, the station remains operational at reduced capacity, preventing severe workflow disruptions.
Industrial estates leverage PV-ESS systems to offset high factory peak charges. Employees charge their personal vehicles at 50% of market rates using excess solar capacity, while the enterprise gains credit points toward national ESG goals, ISO 14064 certification, and local green factory awards.
In areas without stable grid connections, our integrated solar-battery-charging container pods operate in off-grid modes. With 72-hour continuous battery reserves and automated power-smoothing algorithms, isolated mining sites and national parks run robust charging services independent of traditional utility providers.
The EV charging market is migrating rapidly toward the OCPP 2.0.1 protocol. This upgrade supports ISO 15118 "Plug & Charge" features, encrypting customer data while allowing vehicles to serve as bidirectional power units (V2G/Vehicle-to-Grid).
At the same time, liquid-cooling is transitioning from a premium feature to an industry standard. High-current charging rates of 400A+ heat conventional copper wiring rapidly. Liquid-cooled systems circulate specialized dielectric coolant directly through the cable harness, maintaining lightweight, flexible handling for users while guaranteeing stable power curves.
Crucial considerations for B2B wholesale buyers, system architects, and fleet operators.
The GB/T standard, predominantly utilized in China and allied regions, features a distinct pin arrangement and communication protocol compared to CCS (Combined Charging System) standards. While CCS uses a unified connector combining AC and DC terminals, the GBT standard uses separate ports for AC and DC charging. Additionally, GBT communication relies on CAN bus protocol (under GB/T 27930), whereas CCS relies on Power Line Communication (PLC) under ISO 15118. We provide dual-head converters and native multi-standard charging cabinets to bridge these interface requirements seamlessly.
Our GBT DC chargers are engineered with military-grade components and carry IP55/IP65 ingress ratings. The electronic compartments are isolated inside double-wall structures to prevent humidity, dust, and corrosive sea-salt exposure from contacting critical circuit paths. Tested extensively in simulated environments ranging from -35°C to 75°C, they perform reliably in Arctic climates (such as Iceland) and desert conditions (such as Saudi Arabia).
Yes. All Tongxing commercial chargers are natively compatible with the OCPP (Open Charge Point Protocol) 1.6J and OCPP 2.0.1 specifications. This ensures hassle-free integration with remote charging station management networks, commercial payment gateways, local utility billing systems, and dynamic grid-balancing systems worldwide.
For typical commercial parks with moderate EV traffic, the ROI payback period ranges between 3.5 to 5 years. This timeline is accelerated by leveraging off-peak energy storage arbitrage, receiving municipal PV grid subsidies, and generating retail electricity profit margins. Our high-voltage cascaded LiFePO4 batteries feature an extended lifespan of ≥6,000 cycles (at 80% Depth of Discharge), ensuring continuous profitability for over a decade.
We offer full-service OEM and ODM branding options. This includes customized metal enclosure finishes, corporate logo vinyl applications, bespoke graphical user interface (GUI) skins on touchscreens, localized billing software, custom cable lengths, and site-specific power ratings tailored to local utility transformer limits.
