In order to ensure the safe and reliable operation of charging piles, a multi-channel automated charging facility test platform is developed and established in accordance with relevant national technical standards. This test platform improves the single-threaded, manual test efficiency of the original test platform, and solves the problem that the problem that the quality cannot be guaranteed such that it can guarantee that the fast-developing charging facilities can remain safe and reliable on the market. This paper introduces the automated testing platform of charging piles from the aspects of requirement analysis, system architecture, hardware selection and software design. Through experimental verification, the test platform has achieved four-channel parallel automated testing of indicators such as basic functions, electrical performance, communication protocols and interoperability of charging facilities.
