Abstract

This paper presents electric vehicles chargers power quality characterization. The difference between domestic charge for small urban electric vehicle and industrial charge for forklift is addressed. Full charges of lead-acid and NiMH batteries are monitored by recent power analyser, allowing the study of power demands and the voltage and current waveform distortion of the considered charger. The data of the voltage and current waveforms is then used to study and analyse the best solution to mitigate the principal power quality problems. For this, a set of methods and techniques to attenuate the harmonics amplitude by network structural alteration is presented and discussed. The load levelling control concept has been introduced as an alternative option to structural alteration. This comprehensive and effective EV charging control system will respond to the undesirable increases in peak energy demand and power quality degradation, and avoid that the electrical energy network might not be prepared to respond to these requests.

电动汽车充电器特性:负载需求和谐波畸变

本文介绍了电动汽车充电器的电能质量特性。论述了城市小型电动汽车国内收费与叉车工业收费的区别。铅酸电池和镍氢电池的完全充电由最新的功率分析仪监测，允许研究电源需求以及所考虑的充电器的电压和电流波形失真。然后使用电压和电流波形的数据来研究和分析缓解主要电能质量问题的最佳解决方案。为此，提出并讨论了一套通过网络结构变化来减弱谐波幅度的方法和技术。荷载水平控制概念已被引入作为结构改造的替代方案。这一全面有效的电动汽车充电控制系统将对峰值能源需求的增加和电能质量的下降做出响应，并避免电力网络无法应对这些需求。
