电动汽车充电会引起一系列的电能质量问题，主要包括谐波、三相电压不平衡及电压偏差。以国内已投运的出租车充电站电能质量的现场测试为基础，对不同充电站内充电机的谐波电流及充电站谐波电压进行分析；然后研究充电站内的三相电压不平衡以及电压偏差现象；最后针对此问题，给出谐波治理的相关建议并就相关标准进行探讨。

Charging of electric vehicles (EVs) may lead to power quality problems which mainly contain harmonic emission, three-phase voltage unbalance and voltage deviation. Based on the test results of power qualities in several taxi charging stations under operation in China, the harmonic emission of different chargers in different stations as well as the harmonic voltage of the charging stations were analyzed. Then three-phase voltage unbalance and voltage deviation phenomenon in charging station were discussed. At last, against such problems, some recommendations for harmonic suppression were put forward, and discussions were made on relative standards concerning harmonic suppression.
