基于层次分析的电动汽车非车载充电机技术发展趋势分析

Analysis on the Trend of off-board Charger Technology Based on AHP Model

提出了新能源汽车传统非车载充电机的短板滞后问题,探讨了新兴非车载充电机的创新优点及仍待突破的局限,在此基础上结合来自会议的专家数据建立层次分析模型,根据3个评价非车载充电机性能的最主要准则,得出传统交流充电桩和传统直流充电桩亟待改建、柔性充电堆对人们需求及社会发展的适用性最强的结论;同时肯定了碳化硅充电桩和移动式充电桩对完善充电桩市场边角部分的良好补充作用,从而对中国新能源汽车非车载充电机市场的发展趋势前景进行展望,对未来主要流行使用的非车载充电机类型进行了合理预测。

This paper presents the shortcoming of lagging problem in the traditional off-board charger of the new energy vehicle, and discusses the innovative advantages and limitations in the newly emerged off-board chargers. On this basis, a hierarchy analysis model has been established by combining the data from the conference for evaluating the performance of off-board chargers in accordance with three main criteria. The results turn out to be： the traditional AC charging pile and DC charging pile need to be rebuilt, while the flexible charging pile is most applicable to people＇s needs and social development. Meanwhile, it is affirmed that the silicon carbide charging pile and the mobile charging pile could be supplementary in the marginal electric pile marl, et. In such a manner, the prospect of the development trend in the off-board charger market of China new energy vehicles is analyzed; the most popular type of off-board chargers in the future is reasonably predicted.
