China Factory Suppliers Type1 Type2 7-22KW EV Charging Station Wallbox 32A OCPP 4G AC Electric Car Charger

Dynamic Load Balancing Function for EV Chargers
Our advanced EV charger, designed by leading China suppliers and manufactured in our state-of-the-art factory, features a Dynamic Load Balancing (DLB) function. This innovative technology ensures that when the EV charger operates simultaneously with other household appliances, the total household current remains within safe limits. By setting the maximum current value on the DLB box, our charger intelligently reads and adjusts the charging current (ranging from 6A to 32A) based on the available idle load. This prevents home overload and allows efficient use of the existing power supply without the need for additional power sources or costly home line upgrades. Experience the perfect balance of safety and efficiency with our DLB-enabled EV chargers, produced by trusted manufacturers in China.

    Advantages

    Fast Charging

    DLB charging stations support fast charging, significantly reducing charging time and enhancing the convenience of electric vehicles.

    Intelligent Management
