What should be tested in AC charging pile testing?

What should be tested in AC charging pile testing? Taking XL-943S AC charging pile detection equipment as an example, the items of AC charging pile field detection include:

1. Metrological verification

Reference standard: JJG 1 148-2022 Verification regulation of AC charging piles for electric vehicles.

XL-943S AC charging pile detection equipment can complete all relevant metrological verification detection items with load, as follows:

2. Interoperability test:

Reference standard: conducted charging interoperability test item in GB/T 34657. 1-20 17.

XL-943S AC charging pile testing equipment can complete all interoperability testing items with loads, specifically as follows: check charging mode and connection mode, confirm connection, test charging readiness, test start and charging stage, test normal charging end, test charging connection control timing, test CC disconnection, test CP disconnection, test CP grounding, test protection grounding conductor continuity loss, test output overcurrent, test disconnection switch S2 and test CP loop voltage limit.

3. Inspection items in the acceptance stage and operation stage of State Grid:

Reference standard: Intelligent Marketing Pilot [2065438+08] No.45 Notice of State Grid Marketing Department on Printing and Distributing the Work Plan for Further Strengthening the Quality Evaluation of Electric Vehicle Charging Equipment.
