中国超快充电站全生命周期经济性分析

摘 要：超快充电技术通过大幅度提升充电设备的充电功率，可以有效改善电动汽车用户的充电体验，但其运营经济性的分析是其投资推广的前提条件。文章针对超快充电站的经济性展开理论研究。基于全生命周期理论，对充电基础设施的成本收益结构进行分析，建立充电基础设施经济性评估模型，并提出相应的评价指标。以6.6 kW常见慢充充电桩和350 kW超快充电站为对象，完成二者全生命周期成本收益的计算，并进行对比分析。研究成果将为我国超快充电站的建设和推广，以及相关政策的制定提供有价值的参考。

Life-cycle Economic Assessment of Ultra-fast Charging Station in China

Ultra-fast charging technology improves customers experience effectively by boosting the charging power of charging equipment. Operating economy of charging infrastructure should be chosen as a precondition for its promotion. Theoretical research on operating economy of ultra-fast charging infrastructure is carried out in this paper. The analysis on the costs and revenues structure of operating charging infrastructures is conducted and the economic model is constructed based on the theory of life cycle cost. Then the economic indexes are used to assess the operating economy. The life-cycle economic assessments of the 6.6 kW AC charging piles and the 350 kW ultra-fast charging station are calculated, compared and discussed. The research results can provide an important reference for promoting ultra-fast charging station and making relevant policies.
