As the global electric vehicle (EV) market shifts toward 800V architectures and ultra-fast charging, the role of Wholesale DC DC EV Charger Manufacturers has evolved from simple hardware assembly to complex energy ecosystem integration. At TONGXING NEW ENERGY TECHNOLOGY CO., LTD., we provide the "Information Gain" required for B2B stakeholders to navigate the transition from traditional grid charging to decentralized, smart-energy-coupled infrastructures.
DC-DC charging technology, particularly in the context of solar-to-vehicle (S2V) and battery-to-vehicle (B2V) applications, represents the peak of efficiency by eliminating the multiple conversion losses inherent in AC-to-DC rectification. Our systems are engineered to maximize throughput while minimizing heat signature, ensuring a lower Total Cost of Ownership (TCO) for commercial operators.
Equipped with 18 automated assembly lines and IoT-enabled quality control systems, achieving a 95% production automation rate. Our 72,000m² facility is designed for high-capacity wholesale fulfillment.
Over 20+ specialists focused on power electronics and embedded systems. We hold 12 utility model patents and have achieved a 78% reduction in standby power consumption (2021-2023).
From circuit topology optimization to OCPP 2.0 protocol development, our team manages the entire hardware and software lifecycle in-house to ensure reliability.
Transitioning from traditional IGBT modules to SiC MOSFETs. This allows for higher switching frequencies, reducing the physical size of the charger by 30% while increasing conversion efficiency to over 97.5%.
Our upcoming DC charger series will support Vehicle-to-Grid (V2G) capabilities, allowing EV fleets to act as mobile battery storage, providing grid stabilization and new revenue streams for owners.
For ultra-fast charging stations (360kW-960kW), we are implementing liquid-cooled charging cables and modules to maintain 500A continuous output without thermal throttling.
Integration with ISO 15118 (Plug & Charge) and OCPP 1.6J/2.0.1. Compliant with CE and local grid regulations across Germany, Norway, and the UK. Built to withstand Arctic conditions down to -35°C.
CCS1 and NACS compatible solutions. Our DC fast chargers support high-duty cycle operations for electric logistics trucks and transit buses, featuring dynamic load balancing to prevent grid overloads.
Designed for high-density environments. Our compact 120kW units are ideal for shopping mall parking and public transport interchanges in Southeast Asia and Australia, with IP65 dust and moisture protection.
As a leading China-based manufacturer, Tongxing leverages the world's most mature EV ecosystem. Our "Efficiency Advantage" isn't just about cost—it's about the speed of innovation and supply chain security.
| Performance Indicator | Traditional Grid Charging | Tongxing Integrated Solution | Improvement Gain |
|---|---|---|---|
| PV Self-Consumption Rate | 50% | 85%+ | ↑70% |
| Comprehensive Electricity Cost | 0.85 USD/kWh | 0.62 USD/kWh | ↓27% |
| Annual Carbon Reduction | Base | 40% - 60% Reduction | Certified Green |
6-12 solar panels generating 8-15 kWh daily. Our 7kW/11kW chargers schedule charging for off-peak hours, saving $3,000-$5,000 annually on electricity bills.
Modular storage systems (100kWh-10MWh) release power during peak hours, reducing enterprise grid load stress and arbitrage benefits by 30%.
Containerized deployment for remote sites. 72-hour continuous power supply even with minimal sunlight, perfect for mining and campsites.
Q: What is the primary advantage of a DC-DC charging architecture over AC-DC?
A: DC-DC charging directly interfaces with battery storage or solar arrays. By bypassing the traditional AC rectification stage, we eliminate a conversion step that usually loses 5-8% of energy. This means faster charging with significantly less heat generation.
Q: How does Tongxing ensure global interoperability with different EV brands?
A: Our chargers undergo rigorous testing with the "Golden Test" suite for OCPP 1.6J/2.0.1 and are compatible with Tesla, BYD, Volkswagen, and Hyundai. We support CCS1, CCS2, CHAdeMO, and GB/T standards out of the box.
Q: What localized support do you offer for international distributors?
A: We provide white-label (OEM/ODM) branding, remote diagnostic cloud platforms, and a 24-month comprehensive warranty. Our engineers provide 24/7 technical support and certification documentation for local grid approvals.
