Traditional 7kW AC chargers are no longer sufficient for modern long-range EVs. The industry is pivoting toward compact, high-efficiency 20kW-40kW DC wallboxes that can provide 100km of range in under 30 minutes right in your garage.
V2H (Vehicle-to-Home) technology is transforming EVs into mobile energy storage units. Our latest systems support bidirectional power flow, allowing homeowners to power their houses during grid outages.
Smart algorithms now predict electricity price fluctuations, scheduling charging sessions during off-peak hours to reduce costs by up to 60% while balancing home load to prevent circuit overloads.
A National High-Tech Enterprise Pioneering Smart Charging Solutions. With over 23 years of specialized expertise in the power electronics sector, Tongxing has evolved from a component manufacturer to a global leader in integrated energy ecosystems. Our 72,000m² intelligent production base is a testament to our commitment to scale and precision.
Customized DC fast charging hubs for logistics and corporate fleets, integrating OCPP 1.6J/2.0 for seamless billing and remote management across multiple locations.
Direct coupling of rooftop solar panels with high-capacity LiFePO4 energy storage and EV chargers. This holistic approach reduces grid dependence by up to 85%.
Every unit is engineered to meet regional standards: CE for Europe, UL for North America, and IEC for international markets. We provide localized technical support and 24-month warranties.
| Indicator | Traditional AC Charging | Integrated DC+Solar Solution | Improvement Gain |
|---|---|---|---|
| PV Self-Consumption | 50% | 85%+ | ↑ 70% |
| Comprehensive Cost/kWh | 0.85 USD | 0.62 USD | ↓ 27% |
| Charging Speed (100km) | ~4 Hours | ~30 Minutes | 8x Faster |
| Carbon Footprint | Standard Grid Mix | 40%-60% Reduction | Eco-Certified |
Miniaturization of 40kW DC modules using GaN (Gallium Nitride) technology, allowing home chargers to fit in standard AC wallbox dimensions.
Standardization of bidirectional protocols across all major EV brands, enabling "Charging-as-a-Service" where homeowners can sell energy back to the grid.
Development of resonance-based wireless charging pads for residential garages, removing the need for physical cables and connectors.
While AC is standard, DC chargers bypass the car's limited onboard converter, allowing for significantly higher speeds (up to 40kW) which is essential for large-battery SUVs and commercial vehicles used residentially.
Our units are IP55/IP65 certified and tested from -35°C to 75°C. We use military-grade thermal management and dual-core redundancy protection to ensure 99.9% uptime.
Yes, we offer full OEM/ODM services, including custom enclosure designs, UI/UX for the touch screens, and branded APP integration for our B2B partners.
