TONGXING operates at the heart of the global electronics hub, leveraging a vertically integrated supply chain. This ensures 7kW EV charger production benefits from immediate access to high-grade semiconductors, copper windings, and advanced polymers, reducing lead times by 30% compared to Western manufacturers.
With 23 years of expertise and a 72,000m² intelligent production base, we don't just assemble; we innovate. Our 20+ specialized engineers focus on "Power Electronics Optimization," resulting in a 78% reduction in standby power consumption across our 7kW-22kW AC range.
Our 7kW units are engineered for local markets. From CE (EN 61851) for Europe to UL certification for North America, we navigate complex regulatory landscapes including UK CA and French "Ze Ready" standards, ensuring zero-friction market entry for our B2B partners.
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.
18 automated assembly lines and IoT-enabled quality control systems, achieving 95% production automation rate.
140+ certified engineers and a 40-member ISO-9001 audit team ensure every 7kw charger meets rigorous safety protocols.
Hardware Mastery: Circuit topology optimization. Software Expertise: OCPP 1.6J/2.0 protocol development.
The 7kW AC Wallbox is the gold standard for home use. Our units support Dynamic Load Balancing (DLB), protecting household grids from overloading when heavy appliances are active. Integration with mobile APPs allows users to schedule charging during off-peak hours, saving up to 60% on energy bills.
For logistics and ride-sharing fleets, our 7kW chargers offer a cost-effective overnight charging solution. Equipped with RFID and OCPP 1.6J, fleet managers can monitor energy consumption and billing per vehicle with 99.9% accuracy.
Hotels and shopping malls utilize our 7kW pedestals for "Destination Charging." Our IP65-rated units withstand extreme weather (-35°C to 75°C), providing reliability in diverse climates from Iceland to Saudi Arabia.

Prioritizes PV/storage power, automatically supplementing with low-cost grid power during off-peak hours.
100% renewable energy use, achieving zero carbon emissions for sustainable enterprises.
Automatically switches to backup power during grid outages, ensuring 72-hour supply for essential electronics.
As a leading China 7kw EV charger manufacturer, we recognize the shift toward Vehicle-to-Grid (V2G) technology. Future 7kW AC units will not just charge the car; they will allow the vehicle to act as a mobile power bank, selling electricity back to the grid during peak demand. This bi-directional capability is the cornerstone of the next-generation smart city.
Furthermore, AI-driven energy dispatching is becoming mandatory. By analyzing user behavior and grid stability in real-time, our chargers optimize the charging curve to extend battery life by up to 15%. This "Information Gain" is why global enterprises choose Tongxing as their long-term infrastructure partner.
A: 7kW (32A single-phase) provides the perfect balance between charging speed and home electrical capacity. It can fully charge a standard 60kWh EV battery overnight (approx. 8-9 hours) without requiring expensive grid upgrades typical of 11kW or 22kW three-phase systems.
A: Our reliability stems from our 98.6% field success rate. Every unit undergoes 24-hour full-load aging tests and is equipped with dual-core redundancy protection systems for over-voltage, under-voltage, and leakage protection (Type A + 6mA DC).
A: Yes. Via OCPP 1.6J or 2.0.1 protocols and our open API, our 7kW chargers seamlessly integrate with commercial BMS, allowing for unified energy management and automated billing.
