23 Years of Expertise in Power Electronics and Renewable Infrastructure
As a certified National High-Tech Enterprise, Tongxing has dedicated over two decades to redefining energy landscapes. We specialize in the R&D, production, and global distribution of advanced EV charging ecosystems. Our portfolio is exhaustive, ranging from 3.5KW residential units to 960KW ultra-fast Level 3 charging stations.
Level 3 charging, also known as DC Fast Charging (DCFC), is the backbone of the electric vehicle revolution. Unlike Level 1 or Level 2 AC charging, our Level 3 systems convert AC power to DC within the station, delivering high-voltage electricity directly to the vehicle's battery. This enables charge times as fast as 10-15 minutes for a 200km range, making it essential for commercial fleets, highway corridors, and urban hubs.
Years Industry Experience
Intelligent Production Base
Certified Technical Engineers
The core of our "Made in China" competitive advantage
18 automated assembly lines and IoT-enabled quality control achieving a 95% automation rate.
Expertise in circuit topology optimization, OCPP 1.6J/2.0.1 protocol development, and thermal management.
12+ utility model patents and a dual-core redundancy protection system for maximum uptime.
40-member ISO-9001 audit team ensuring every unit passes rigorous electromagnetic and safety tests.
For global enterprises, sourcing Level 3 EV chargers from Chinese manufacturers is no longer just about cost—it’s about speed to market and technical maturity. The Chinese supply chain provides unprecedented vertical integration. From high-purity copper for charging cables to the rare-earth magnets in cooling fans, we have immediate access to raw materials.
Information Gain: Unlike many western assemblers, Tongxing controls the Power Module manufacturing process. The power module is the most critical component of a Level 3 charger, accounting for roughly 50% of the cost. By designing our own resonant converter topologies, we achieve energy efficiency ratings of ≥96%, significantly higher than the industry average of 92%. This translates to thousands of dollars in energy savings over the station’s lifecycle.
Furthermore, our location in China’s tech hubs allows for rapid prototyping. We can take a client's custom requirement—such as specialized payment gateways or localized grid balancing algorithms—and move from design to functional prototype within 21 days.
Integrated Photovoltaic-Energy Storage-EV Charging (VPP Ready)
Our "Solar-Storage-Charging" system stores low-cost power during off-peak hours and releases it during peak hours. This alleviates grid load stress and reduces grid electricity costs by up to 40%.
| Indicator | Traditional Solution | Integrated Solution | Improvement |
|---|---|---|---|
| PV Self-Consumption | 50% | 85%+ | ↑70% |
| Electricity Cost | 0.85 USD/kWh | 0.62 USD/kWh | ↓27% |
| Carbon Reduction | - | 40%-60% | ↑↑↑ |
Ensuring your infrastructure meets every regional standard
Fully compliant with CE (Europe), UL (North America), TUV, and GBT (China). We handle the regulatory burden so you don't have to.
Our stations support OCPP 1.6J and 2.0.1, ensuring seamless integration with third-party backend management systems and mobile apps.
IP55/IP65 rated hardware tested from -35°C in Iceland to 75°C in Saudi Arabia. Reinforced waterproof and dustproof seals for longevity.
Ready-to-use integration for credit card terminals (Nayax, Ingenico), QR codes, and RFID swipe systems to meet local consumer habits.
