EVD non-vehicle charger laboratory test device

EVD non-vehicle charger laboratory test device



The integrated test device for non-vehicle DC chargers, together with a three-phase programmable AC power supply and a load box, form a DC charger test system. Among them, the three-phase programmable AC power supply provides power to the charger, which can simulate voltage overvoltage and undervoltage And other characteristics, the load box is used to simulate the load of electric vehicles.

The integrated test device for DC chargers is composed of:

◆ Industrial computer mainframe        

◆ Display       

◆ Programmable AC power supply       

◆ System control unit        

◆ Power analyzer                              

Interface simulator        

◆ DC load components                       

◆ Oscilloscope (optional)
