Key Product Advantages

 

1. Wide Voltage Compatibility for All Mainstream EVs

 

With an output voltage range of 200-750V (1000V optional), the charger works with both 400V platform passenger cars and 800V high-voltage models. It supports three mainstream interface standards - CCS, CHAdeMO and GB/T - covering almost all EV models on the market and eliminating "vehicle-pile mismatch" for public charging scenarios.

 

2. High Efficiency for Lower Operating Costs

 

With a peak efficiency of up to 95% and power factor higher than 0.99, the charger minimizes energy loss during power conversion, effectively reducing electricity costs for operators. It is especially suitable for high-frequency commercial charging scenarios, delivering long-term operational savings.

 

3. Reliable Performance for Outdoor Deployment

 

With an IP54 ingress protection rating, the wallbox operates stably in outdoor environments exposed to wind, rain and dust. Its -20℃ to +50℃ operating temperature range adapts to most climate regions worldwide, maintaining consistent charging performance even in extreme summer heat or cold winter conditions.

 

4. Smart Operation & Remote Management

 

Fully compliant with the OCPP 1.6 protocol, the charger can be seamlessly connected to mainstream charging operation platforms, supporting remote start/stop, charging data monitoring and fault alarms. It is also equipped with a 5-inch display for on-site status viewing, convenient for both operators and end users.

 

 

Typical Application Scenarios

 

Commercial parking lots & shopping malls: fast charging services for customer vehicles

Hotels & office buildings: charging support for guests and employees
