摘要
在新能源汽车市场高速发展下,其续航里程却提升缓慢。为了降低冬季PTC(Positive Temperature Coefficient正温度系数)加热下对续航里程的影响,热泵系统是目前效率最高的方案。本文首先对于新能源汽车不同的热泵模式进行优缺点分析和比较。其次,结合国内外学者的研究,分析了在新能源汽车热泵设计中所要面对的部分难点,并给出了解决方案。最后,为热泵系统未来的发展方向提出了建议。
In the rapid development of the new energy vehicle market,its cruising range has grown slowly.In order to reduce the impact of PTC heating on cruising range in winter,the heat pump system is currently the most efficient solution.This paper first analyzes and compares the advantages and disadvantages of different heat pump modes of new energy vehicles.Secondly,combined with the research of scholars at home and abroad,it analyzes some difficulties in the design of new energy vehicle heat pump and gives solutions.Finally,recommendations are made for the future direction of the heat pump system.
