which can ensure that the vehicle is fully charged in about one hour. The charging pile adopts flexible charging technology,

and the power is automatically distributed according to demand (maximum 120KW for a single gun,

The two guns share 60KW equally, and the two guns are charged at the same time and automatically allocated according to the vehicle battery demand),

which can greatly improve the power utilization of the charging pile.

  • The 120KW DC double-gun charging pile adopts a modular design, and the product capacity covers each power segment between 20kW-120kW;

the “modular” design is adopted inside the whole machine, which not only ensures the compact layout but also increases the reliability of the whole machine.

The electric vehicle charger adopts a 7-inch touch screen, LCD design, and menu structure so that all operations are clear at a glance.

The electric vehicle charger has functions such as electricity billing, data statistics storage, collection, and transmission.

2) Charging method
  • Scan code charging: It has a wide range of application scenarios, and can directly use the mobile phone APP to operate and charge.
  • Swipe card charging: suitable for unified management of operating vehicles, special car cards,

statistics of the form of the vehicle, and the charging amount can be counted through the charging card.

  • Bank card/credit card charging: Most countries still mainly use bank cards or credit cards for payment. The E V charger is equipped with a POS machine,

and the user can directly swipe the card to charge.

3)Technical Features
  • The system adopts active protection, flexible charging, and other technologies, which can effectively improve charging safety and prolong battery life;
  • According to the needs of users, you can choose to use scanning charging or swiping card charging to meet the unattended conditions ;
