摘　　要：为了检测和诊断电动汽车交流充电桩可能出现的故障,结合充电桩内电气元器件的特性,分析了交流充电桩的主要故障类型,通过提取交流充电桩内主回路的相关电特征量,并运用故障字典法对故障进行检测。随后建立实验平台,模拟各类故障发生,验证故障字典法对于交流充电桩故障检测的有效性。结果表明,故障字典法对于检测交流充电桩内可能发生的典型故障具有很好的诊断能力。In this paper, according to the characteristics of the electrical components in the AC charging piles, the main fault types in AC charging piles are analyzed in order to diagnose and detect the possible faults. Extracting the relevant electrical characteris-tics of the main circuit and using the fault dictionary method, it detects and diagnoses the faults of AC charging piles. An experimental platform is built to simulate the various fault states and verify the effectiveness of the fault dictionary method for AC charg-ing pile fault detection. The results show that the fault dictionary method has the good capability to detect the typical faults that may occur in AC charging piles.
