1.Visual inspection: check whether the overall structure of the charging pile is complete, and whether there are undesirable phenomena such as damage, oil leakage, and leakage on the surface. At the same time, check whether the indicator light of the charging pile is normal, whether the touch button and switch operation are smooth, whether the display screen is displayed normally, and whether the sound and buzzer prompt functions of the device are normal.
2.Installation structure inspection: check whether the installation structure such as the foundation and bracket of the charging pile meets the requirements of the specification, whether there are lightning protection and grounding measures, and whether the grounding resistance meets the national standard.
3.Charging performance testing: test the DC and AC output power, conversion efficiency, safety protection function, etc. of the charging pile. The charging pile is required to be able to provide a power supply that meets the specified requirements within the specified time, and can adjust itself according to external conditions (such as temperature, humidity, grid voltage, etc.) to ensure the stability of the output voltage and current.
4.Safety performance testing: Charging piles need to comply with relevant national safety regulations, including electrical safety, mechanical safety, environmental adaptability and electromagnetic compatibility. In terms of electrical safety, it is necessary to test the insulation resistance, working grounding resistance, overcurrent protection, etc. of the charging pileIn terms of mechanical safety, it is necessary to check the structure, fixation and connection, installation dimensions of the charging pile, etc.;In terms of environmental adaptability, it is necessary to test the working stability of the charging pile in different environments such as high temperature, low temperature, humidity, and vibrationIn terms of electromagnetic compatibility, it is necessary to test the electromagnetic interference performance of charging piles.
5.Charging protocol compatibility testing: Different brands of charging piles may have different charging protocols, so it is necessary to test the protocol compatibility of charging piles to ensure that they can effectively communicate and charge with various brands and models of electric vehicles.
In short, the testing standards of charging piles are to ensure that their quality and safety performance meet the relevant national standards and user needs, so as to ensure the safety, stability and efficiency of electric vehicle charging.
