As a National High-Tech Enterprise with over 23 years of specialized experience in power electronics and energy systems, Tongxing is not merely a manufacturer but a pioneer in the global electric vehicle supply equipment (EVSE) sector. Our operations are anchored in a mission to bridge the gap between advanced Chinese manufacturing efficiency and the stringent quality demands of the international market.
Our comprehensive R&D ecosystem supports the entire lifecycle of EV charging—from initial circuit design and firmware development (OCPP 1.6J/2.0.1) to high-volume automated production. We provide scalable solutions for residential wall boxes, commercial rapid chargers, and ultra-fast DC stations up to 960KW.

Our 18 automated assembly lines achieve a 95% automation rate, ensuring microscopic precision in PCB SMT and cabinet assembly. This translates to a 98.6% field reliability rate, audited by TUV.
By controlling the supply chain from raw sheet metal to proprietary BMS and OCPP software, we reduce lead times by 30% compared to European competitors, offering unmatched cost-to-performance ratios.
Every Wall Box EV charger undergoes a 4-hour full-load aging test and 12 strict safety checks, including leakage protection, over-voltage, and thermal runaway simulations.
Modern EV charging requires more than just power; it requires contextual intelligence. Tongxing chargers are engineered for diverse global environments.
Our 7-22kW AC Wallboxes integrate with home energy management systems (HEMS). Using Dynamic Load Balancing (DLB), the charger monitors household consumption in real-time, preventing circuit breakers from tripping while ensuring the EV is fully charged by morning.
For logistics hubs and office complexes, we provide multi-gun DC systems (60kW-240kW) with OCPP 1.6J/2.0 compliance. This allows seamless integration with third-party billing platforms and fleet management software.
Reliability is built into our DNA. Our products meet the most rigorous international certifications to ensure safe operation in any climate.
| Region | Certification | Technical Focus |
|---|---|---|
| Europe | CE (LVD/EMC), TUV, UKCA | IEC 61851-1, Type 2 Connectivity |
| North America | UL Listed, Energy Star | SAE J1772, NEMA 4 Enclosures |
| Global | ISO 9001, ISO 14001 | Environmental Management & Manufacturing Quality |
The next decade of EV infrastructure will be defined by energy interaction. Tongxing is currently developing:
Turning EVs into mobile batteries to stabilize the grid during peak demand, creating a new revenue stream for vehicle owners.
Enabling ultra-fast charging up to 600A without cable overheating, reducing 10%-80% charge time to under 10 minutes.
Using machine learning to predict component failure before it happens, reducing station downtime by 45%.
