电动汽车直流充电桩自动化测试平台的设计与应用

Development and application of automated test platform for DC charging piles of electric vehicles

为了保障充电桩的安全、可靠运行,依据国家相关技术标准,研发并建立了一个多通道的自动化充电设施测试平台。该测试平台改善原来测试平台单线程、人工测试效率低,质量不能保障的问题,以保障快速发展的充电设施能够安全、可靠地投放市场。从需求分析、系统架构、硬件选型、软件设计等方面对充电桩自动化测试平台做了介绍。通过实验验证,测试平台实现了对充电设施基本功能、电气性能、通信规约、互操作性等指标的四通道并行自动化测试。

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.
