摘要
为精准量化动力电池全生命周期真实使用成本从而为消费者提供透明的长期用车成本参考并为社会评估电动汽车普及的经济效益与可持续性提供科学依据,以装配磷酸铁锂电池的电动汽车为研究案例,构建了快充和慢充模式下动力电池消费者全成本模型,探究了2种模式下动力电池消费者全成本的影响因素以及该成本与影响因素之间的关系,并且考虑了动力电池单体循环次数和电动汽车行驶里程之间的转化等问题,从而将动力电池的容量衰减纳入模型中。为了验证模型的有效性,分别对2种模式下消费者全成本进行实例分析,并揭示了动力电池实际容量保持率是消费者全成本最关键的影响因素。
To accurately quantify the real-life usage cost of power batteries over their entire lifecycle,provide consumers with transparent long-term vehicle cost references,and offer a scientific basis for society to assess the economic benefits and sustainability of electric vehicle adoption,this paper,taking electric vehicles equipped with lithium iron phosphate batteries as a case study,constructs consumer total cost models of power batteries in fast and slow charging modes.The influencing factors on consumer total costs of power batteries in these two charging modes and the relationships between total costs and these factors are investigated.Taking the conversion between the number of the individual cycles of power batteries and the driving distance of electric vehicles into account,it incorporates the capacity degradation of power batteries into the model.To validate the effectiveness of the model,it conducts an instance analysis of the total cost.The findings show that the actual capacity retention rate of power batteries is the most critical factor affecting total consumer cost.
