Industry-leading DC and AC charging technology for residential and commercial applications.
While traditional "Level 3" charging has been synonymous with industrial DC fast charging stations, a new era of Compact Residential DC Fast Chargers is emerging. TONGXING NEW ENERGY TECHNOLOGY CO., LTD. is at the forefront of this transition, bridging the gap between slow overnight AC charging and instantaneous commercial power delivery.
Global demand for "At-Home Level 3" solutions is driven by the rise of 800V vehicle architectures and high-capacity battery packs (100kWh+), where standard 7kW AC chargers require over 14 hours for a full charge. Our 20kW-40kW DC residential units reduce this time by 75%, providing a full charge in less than 3 hours.
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.
Scaling Innovation Through Automated Intelligence
Equipped with 18 automated assembly lines and IoT-enabled quality control systems, achieving a 95% production automation rate. Every unit undergoes rigorous 48-hour burn-in testing.
Our 20+ R&D specialists master power electronics and embedded systems, focusing on circuit topology optimization and thermal management for high-density DC modules.
Holding 12 utility model patents and achieving a 78% reduction in standby power consumption (2021-2023). Our dual-core redundancy protection ensures fail-safe operation.
Meeting the Demands of Large-Scale Infrastructure Developers
The Full-Scenario Energy Ecosystem Solution
Rooftop solar panels provide real-time power, meeting 30%-50% of charging demand at as low as 1/3 of peak grid prices.
Store low-cost power during off-peak hours and release it during peak hours, reducing grid costs by 40% per station.
Supports 120kW-960kW ultra-fast charging, adding 200km range in 10 minutes via AI power distribution.
| Indicator | Traditional Solution | Integrated Solution (Tongxing) | 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 |
Beyond the Plug: The Future of Residential Energy Hubs
Future Level 3 home chargers will act as bi-directional inverters, allowing your EV battery to power your home during blackouts or sell energy back to the grid (Virtual Power Plants).
Transitioning to SiC MOSFETs to achieve 98%+ efficiency, reducing heat dissipation and allowing for smaller, fanless home DC chargers.
Eliminating the need for apps or cards. Authenticate and start charging simply by plugging in, with encrypted secure communication.
Our solutions are engineered for Extreme Environment Resilience. IP55/IP65-certified stations perform from -35°C to 75°C. With partnerships across 45+ countries, we ensure:
Expert Insights into Residential Level 3 Charging
Yes, but with caveats. Standard Level 3 commercial chargers (100kW+) exceed residential grid capacity. However, our "Home Level 3" units are compact 20kW-30kW DC chargers that can operate on 3-phase residential power, offering significantly faster speeds than AC wallboxes.
Ensure the manufacturer provides CE (for Europe), UL (for North America), and IEC 61851 compliance. All Tongxing products meet these international safety standards.
Through an EMS (Energy Management System), the charger prioritizes surplus solar energy during the day. Our "Economic Mode" automatically switches between PV, battery storage, and grid power to minimize costs.
