摘要
为总结国内外无线充电道路技术进展,对比分析电磁谐振式、电容式和辐射式等电能传输方法的优缺点,重点分析提高电磁谐振式工作性能的方法,并结合城市出租车、城市公交系统和公路交通系统的充电需求阐释道路无线充电设施部署方法。分析表明:当前无线充电效率相对偏低,需进一步提高充电效率,但其影响因素众多,需进一步加强对电容式和辐射式功率传输的研究及三种方式之间的经济效益对比,并考虑将无线充电道路设施的部署优化模型进行试点运行和测试,从而更快推进出租车、城市公交系统以及公路交通系统无线充电的应用化。
In order to summarize the progress of wireless charging road technology at home and abroad,the advantages and disadvantages of electric energy transmission methods are compared and analyzed,such as electromagnetic resonant type,capacitive type and radiant type,and the methods to improve the working performance of electromagnetic resonance are especially analyzed.Additionally,the deployment methods of road wireless charging facilities are explained in combination with the charging requirements of urban taxi,urban bus system and highway traffic system.The analysis shows that the efficiency of wireless charging is relatively low at present,which needs to be further improved.However,there are various influential factors,so it is necessary to further enhance the research on capacitive and radiant power transmission and the comparison of economic benefits among the three types,and consider the pilot operation and test of the deployment optimization model of road wireless charging facilities,so as to accelerate the application of wireless charging in urban taxi,urban public transportation system and highway traffic system.
