目的 以可持续设计的有关理论作为指导，以木马设计集团的新能源充电桩产品设计为样例，降低产品使用过程中的人为损耗，为共享汽车的充电问题提出智慧化解决方案。方法 首先，以“DfS”(Design for Sustainability)方法为指导，通过用户访谈构建动态用户画像，挖掘传统充电桩各阶段存在的痛点，并从可持续设计的视角建立新能源充电产品服务系统的理论框架;其次，通过定性及定量的方法挖掘用户显性与隐性需求，总结新能源充电系统的设计策略;最后，利用该策略指导设计新能源充电系统，并利用可持续性晴雨表进行设计验证。结果 提出可持续设计视角下新能源充电系统的设计原则;基于用户需求设计出自动化新能源充电系统，解决传统手动充电带来的过程繁琐的问题。结论 新能源充电系统设计策略的构建能够推动自动化、智能化、网联化和共享化深度融合，实现城市交通体系智慧化发展。

The work aims to take the relevant theories of sustainable design as guidance and the product design of new energy charging pile of Moma Design Group as an example, to effectively reduce the artificial loss during the use of products, and propose intelligent solutions for the charging problem of shared cars. Firstly, the "DfS" (Design for Sustainability) method was used as a guide to build a dynamic user portrait through user interviews, excavate the pain points of traditional charging piles at each stage, and establish the framework of the new energy charging product and service system from the perspective of sustainable design. The design strategy of the new energy charging system was summarized through qualitative and quantitative methods, which guided the design of the new energy charging system, and the design verification was carried out by the sustainability barometer. The design principles of the new energy charging system from the perspective of sustainable design were proposed and an automated new energy charging system was designed based on user requirements to solve the problem of cumbersome process brought by traditional manual charging. The construction of the new energy charging system can promote the deep integration of automation, intelligence, networking and sharing, and realize the intelligent development of urban transportation system.
