Field Inspection Technology and Application of AC Charging Pile Based on Industrial Computer

In this paper, a portable field inspection device based on industrial control computer is developed, which is used to carry out electrical performance test, charging interoperability test and electric energy metering test of singlephase or three-phase AC charging pile. The paper describes the field inspection principle, system structure test process and technical parameters of the device, and finally verify the performance of the device through the practical application, which can meet the needs of field inspection
