An in-depth guide for global distributors, commercial fleet operators, and infrastructure developers.
A National High-Tech Enterprise Pioneering Smart Charging Solutions.
As a certified national high-tech enterprise with 23 years of expertise in the energy sector, Tongxing specializes in R&D, production, and global distribution of innovative EV charging systems. Our comprehensive product portfolio spans from 3.5KW residential chargers to industrial-grade 960KW ultra-fast charging stations, complemented by integrated photovoltaic (PV) and energy storage solutions.
The global demand for "Dual Port" DC fast chargers has increased by 145% YoY. Enterprises are shifting from single-gun installations to dual-port configurations to maximize ROI per parking space and reduce user waiting times at public stations.
Modern Dual Port chargers utilizing SiC (Silicon Carbide) technology offer up to 96.5% efficiency, reducing thermal loss and operational electricity costs by approximately $1,200 per year compared to traditional IGBT models.
Full support for OCPP 1.6J and 2.0 protocols. Our manufacturing lines are ISO 9001 certified, ensuring every unit meets CE (European), UL (American), and GB/T (Chinese) standards for safety and interoperability.

| Indicator | Traditional Solution | Tongxing Integrated Solution | Net Improvement |
|---|---|---|---|
| PV Self-Consumption Rate | 50% | 85%+ | ↑ 70% |
| Comprehensive Electricity Cost | 0.85 USD/kWh | 0.62 USD/kWh | ↓ 27% |
| Annual Carbon Emission Reduction | - | 40%-60% | Significant ESG Gain |
Make Homes Energy Centers: 7kW/11kW AC chargers support APP scheduling, reducing home energy costs by 30% through off-peak optimization.
Applicable for factories, office buildings, and logistics parks. Modular energy storage systems (100kWh-10MWh) provide 72-hour emergency power backup.
Electrify remote areas without stable grid connection. Containerized deployment allows station setup within 72 hours with solar + battery interaction.
1. The Rise of 800V Architecture: Our next-gen dual-port chargers are designed for 800V platforms, enabling a 300km range replenishment in just 10 minutes.
2. V2G (Vehicle-to-Grid) Integration: Future dual-port systems will act as bidirectional energy nodes, allowing EVs to sell excess power back to the grid during peak demand.
3. AI-Driven Load Balancing: Dynamic power allocation between two ports ensures that a single vehicle can draw maximum power if the other port is idle, or split it 50/50 when both are in use.

Dual port chargers provide a much higher "User-to-Charger" ratio. In a commercial setting, this means twice the revenue potential from a single electrical installation. It also provides redundancy; if one connector is damaged, the station remains operational.
We provide full white-label and localization support, including CE/TÜV/UL certifications. Our software team works directly with European grid operators to ensure seamless OCPP 1.6J/2.0J integration with existing backend management systems.
Depending on local electricity rates and usage density, most commercial partners report a full payback (ROI) within 24 to 36 months, especially when combined with our PV-Energy Storage solutions to reduce input costs.
Yes. We offer comprehensive OEM/ODM services, including customized enclosure colors, logo printing, and bespoke UI/UX designs for the 7" or 12" touch screens.
• Economic Mode: Prioritizes PV/storage power, automatically supplementing with low-cost grid power during off-peak hours.
• Low-Carbon Mode: 100% renewable energy use, achieving zero carbon emissions.
