As the global automotive industry undergoes a tectonic shift toward electrification, the demand for robust, high-efficiency DC Fast Charger kWh solutions has never been more critical. TONGXING NEW ENERGY TECHNOLOGY CO., LTD., a national high-tech enterprise, stands at the intersection of power electronics and smart energy management. With over 23 years of specialized experience, we are redefining what it means to be a premier China DC fast charger kWh supplier.
The "Information Gain" we provide isn't just in raw power output; it's in the Total Cost of Ownership (TCO) reduction, Grid Stability through V2X (Vehicle-to-Everything) technology, and the seamless integration of Renewable Energy Sources. Our mission is to transform charging piles from simple utilities into intelligent energy nodes.
Pushing the boundaries of charging speed with liquid-cooled technology for next-gen 800V EV platforms.
A legacy of power electronic innovation ensuring 99.9% uptime for global charging networks.
Global presence with certifications including CE, UL, and TUV to meet local grid requirements.
Traditional air cooling reaches its limits at 250A. Our liquid-cooled DC fast chargers support up to 600A, significantly reducing cable weight while managing thermal stress during ultra-fast kWh delivery.
Moving beyond standard connectivity, our firmware supports advanced smart charging profiles, enabling dynamic load balancing and complex tariff structures for CPOs (Charge Point Operators).
Utilizing machine learning to predict component failure and optimize power module rotation, extending the lifespan of DC chargers by up to 35%.
Our chargers aren't just consumers. We are engineering bidirectional systems that allow EVs to serve as mobile batteries, feeding kWh back to the grid during peak demand.
The future of charging is not just about the charger; it's about the source. We provide a macro solution for Urban Commercial Districts and Industrial Parks:
| Performance Indicator | Standard Charging Station | Tongxing Integrated Solution | Efficiency Gain |
|---|---|---|---|
| PV Self-Consumption Rate | ~45% | 85%+ | ↑ 88% |
| Operational Cost per kWh | Standard Tariff | Reduced by ~27% | ↓ 27% |
| Grid Stress Contribution | High | Buffered / Stabilized | Optimized |
Our 72,000m² intelligent production base is more than just a factory—it is a vertically integrated ecosystem designed for supply chain resilience.

As a leading China DC fast charger factory, we control the entire lifecycle of the product. From the initial circuit topology design to the final burn-in tests in high-temperature chambers, every kilowatt-hour of capacity is verified. Our IoT-enabled quality control system tracks every component, ensuring that if a module fails in a station in Iceland or Saudi Arabia, we can trace the exact batch and root cause within hours.
This "Smart Manufacturing" approach allows us to maintain competitive pricing while delivering military-grade resilience. We utilize SiC (Silicon Carbide) semiconductors in our power modules to achieve efficiency ratings exceeding 96.5%, significantly higher than the industry average of 93-94%.
We handle the heavy lifting of regional standards. Whether it's CCS1 for North America, CCS2 for Europe, or CHAdeMO for Japan, our systems are pre-certified and grid-ready.
For fleet operators and energy brands, we offer full customization—from hardware branding to customized cloud management interfaces.
Our IP55/IP65 units are tested from -35°C to +75°C, ensuring performance in arctic conditions or desert heat without derating.
Quality is determined by the stability of the power modules and the efficiency of the thermal management system. High-quality chargers use SiC modules for better heat dissipation and lower conversion loss, ensuring that the kWh delivered to the battery is clean and stable.
By maintaining a 90% vertical integration rate and strategic reserves of core semiconductors. Our "China Factory 4.0" model allows us to switch between alternative components without compromising on the final output specifications, thanks to our robust R&D engineering team.
Yes. Our chargers utilize Dynamic Power Allocation. While a current EV might only draw 50-150KW, our systems can split the 960KW across multiple "guns" (plugs) to charge up to 8 or 12 vehicles simultaneously at their maximum rated speeds.
With our integrated PV-Storage solutions, the payback period is typically reduced to 3.8 - 5 years, depending on local electricity rates and government subsidies. Our high reliability (98.6% field uptime) ensures consistent revenue stream.
