The 7kW AC EV charger, often referred to as the "Goldilocks" of the EV infrastructure, represents the most critical segment of the electric vehicle transition. Providing a standard 32A single-phase output, it balances cost-efficiency with sufficient charging speed (approximately 35-45km of range per hour). As global EV adoption moves from early adopters to the mass market, the demand for high-quality, wholesale 7kW chargers has surged by 140% year-on-year. For manufacturers and suppliers, the challenge is no longer just "power delivery"—it is about smart grid integration, data security, and multi-protocol compatibility.
TONGXING NEW ENERGY TECHNOLOGY CO., LTD. is a certified national high-tech enterprise pioneering smart charging solutions. Our comprehensive product portfolio spans from 3.5KW residential chargers to industrial-grade 960KW ultra-fast charging stations.
Equipped with 18 automated assembly lines and IoT-enabled quality control systems, achieving 95% production automation rate.
IP55/IP65-certified stations deliver unmatched performance from -35°C to 75°C, with military-grade materials.
We redefine the charging experience through our Photovoltaic-Energy Storage-Charging (PV-ES-C) hub solution. By integrating solar energy and battery storage with our 7kW-960kW charging units, we enable "Zero Carbon" transportation hubs.
Rooftop solar panels provide real-time power, meeting 30%-50% of demand at 1/3 grid electricity prices.
Store low-cost off-peak power and release it during peak hours, reducing costs by 40% per station.
AI power allocation improves multi-unit charging efficiency by 25%, crucial for commercial 7kW deployments.

Deploying 7kW chargers in industrial parks and commercial complexes is the most effective way to reduce ESG footprints while creating a sustainable revenue stream. Our data shows a significant improvement in efficiency compared to traditional grid-only solutions.
| Indicator | Traditional Grid Charger | Tongxing Integrated Solution | Net Improvement |
|---|---|---|---|
| PV Self-Consumption Rate | 50% (Avg) | 85%+ | ↑ 70% Gain |
| Electricity Cost (USD/kWh) | 0.85 | 0.62 | ↓ 27% Reduction |
| Cycle Life (Storage) | 3,000 Cycles | 6,000+ Cycles | ↑ 100% Longevity |
| Annual Carbon Reduction | N/A | 40% - 60% | Sustainable Target |
All our 7kW units are certified to IEC 61851 and 62196 standards. For the North American market, we provide UL-listed 32A/40A units ensuring total safety and grid compatibility.
Essential for residential blocks, our DLB technology prevents local grid overload by communicating with the home's main breaker, adjusting charger output in real-time.
Integrated 4G/Ethernet/Wi-Fi support with OCPP 1.6J/2.0.1 allows for white-labeled management platforms, localized payment gateways, and remote firmware updates (OTA).
7kW Wallboxes are ideal for overnight charging. Using our "Economic Mode," homeowners can prioritize solar power, reducing charging costs to near zero.
Charging employees' EVs during the day using rooftop solar. Integrated carbon tracking assists in obtaining ISO 14064 certification for green factories.
Solution: Solar Array + Storage + 7kW AC. Grid-free operation ensures 72-hour continuous power supply even with only 4 hours of daily sunlight.
Our R&D team is currently focusing on three key pillars for the next generation of 7kW and 22kW charging hardware:
